If you’re working out where to buy Ipamorelin peptide for lab work, you can order from Kylo Peptides, Biotech Peptides, Bluum Peptides, American Peptides, or Thrive Peptides. All five sell lyophilized vials in 5mg or 10mg sizes and publish purity data. The smart way to choose is to compare what arrives with the vial: the lot COA, the identity test, the real quantity, and the price per milligram.

Kylo Peptides is a strong starting point if you want both sizes and a certificate that tests well beyond purity.

Where Can You Buy Ipamorelin Peptide for Research?

You can find research-grade Ipamorelin for sale at Kylo Peptides, Biotech Peptides, Bluum Peptides, American Peptides, and Thrive Peptides. Each lists Ipamorelin as a single compound, names a vial size, and publishes a batch-specific purity figure.

Quick Answer: Top 5 Ipamorelin Supplier 

Prices were checked on 30 September 2026. American Peptides’ 5mg vial showed as sold out that day, so the 10mg was the live option.

Before you buy Ipamorelin peptide from any of them, focus on identity testing and lot matching. A lab that confirms the molecule by mass spectrometry and ties the result to one lot gives you something you can check against your own vial. Price comes after that, once you know what each vial is backed by.

What You Are Actually Buying When You Order Ipamorelin

When you buy Ipamorelin peptide, you’re getting a tiny synthetic chain of five amino acids, freeze-dried into a white cake at the bottom of a glass vial. Every honest listing describes that same molecule the same way, with the same CAS number, formula, and sequence.

Ipamorelin at a glance

• Type: synthetic pentapeptide (five residues)
• CAS number: 170851-70-4
• Molecular formula: C38H49N9O5
• Molecular weight: about 711.86 g/mol (PubChem CID 9831659)
• Sequence: Aib-His-D-2-Nal-D-Phe-Lys-NH2
• Development code: NNC 26-0161
• Format: lyophilized powder

Two of those residues are unusual. Aib and D-2-Nal aren’t standard amino acids, and Kylo’s listing credits them with the compound’s stability and receptor selectivity.

Why Ipamorelin is used as a research compound

Ipamorelin binds to GHSR-1a, the ghrelin receptor, and prompts pituitary cells to release growth hormone. The 1998 paper that introduced it called it “the first selective growth hormone secretagogue” (Raun et al., Eur J Endocrinol 1998;139:552-561).

Selectivity is the whole appeal: it releases GH without the ACTH and cortisol rise seen with older secretagogues. So researchers use it as a clean probe for secretagogue pharmacology, receptor-selectivity work, and neuroendocrine signaling models.

Top Five Ipamorelin Suppliers Compared

Here are five places to buy Ipamorelin peptide, each with a stated vial size, a live price you can check today, and lab data behind it. All five publish a purity figure, and four link an Ipamorelin certificate you can open and read.

#1. Kylo Peptides: 5mg and 10mg Ipamorelin

Ten-test lot panel on Ipamorelin. Kylo Peptides is a strong place to buy Ipamorelin if you want a certificate that goes well past purity. Its latest 5mg Optiq report runs ten checks, from LC-MS identity and potency to sterility, endotoxin, and residual solvents.

• Sizes: 5mg and 10mg
• Listed price: $79.95 (5mg), $109.95 (10mg)
• Purity and identity testing: ≥99% HPLC target with LC-MS identity
• Latest COA on file: Optiq Health Labs, lot SD-260729-1, 99% purity, LC-MS identity, report dated 10 August 2026
• Shipping: 24-hour dispatch, free over $150, 30-day money-back policy

We pulled that certificate from Kylo’s public COA library, where heavy metals, yeast and mold, pH, and water activity also show as pass. The library includes reports from four independent labs: Janoshik, Freedom Diagnostics, Vanguard, and Optiq, and the CJC-1295 + Ipamorelin blend has its own Vanguard report there.

Kylo states that each certificate matches the lot number printed on the vial. The listing also names the molecule by CAS, development code, and sequence, and both sizes sit side by side.

#2. Biotech Peptides: 5mg Ipamorelin

Measured mass matches expected Ipamorelin. Biotech Peptides’ 5mg Ipamorelin comes with an MZ Biolabs certificate that prints the measured mass (711.42 Da) right beside the expected 711.38 Da. The vials are “Synthesized and Lyophilized in the USA,” per the listing.

• Sizes: 5mg only
• Listed price: $46 (was $53); $43.70 each at 5-9 units, $41.40 at 10+
• Purity and identity testing: HPLC purity with mass-spec identity on one sheet
• Latest COA on file: MZ Biolabs, lot 3141040, 99.42%, analysis dated 15 July 2026
• Shipping: free USPS Priority on orders over $200

The downloadable certificate names the lab and the analyst, and its purity figure comes from the same HPLC-UV-MS run.

The panel stops at purity and identity, so there’s no endotoxin or content figure on it. That’s fine for many projects and worth knowing up front. Check Biotech’s 5mg Ipamorelin.

#3. Bluum Peptides: 10mg Ipamorelin

Endotoxin report beside the Ipamorelin COA. Bluum puts its lab results block near the top of its Ipamorelin page. The current lot, IPA102607-122A, shows 99.38% purity with an endotoxin result of ≤0.05 EU/mL, and an earlier lot sits right below it.

• Sizes: 10mg only
• Listed price: $59; 5% off at five vials, 10% off at ten or more
• Purity and identity testing: UPLC-MS by Horizon Analytical, spec >98%
• Latest COA on file: report 1017787, lot IPA102607-122A, analyzed 12 July 2026
• Shipping: free 2-day shipping on orders over $200

The Horizon Analytical certificate matches the lot shown on the listing, which makes the paper trail easy to follow.

One small limit: there’s no 5mg option, so a smaller pilot run still means buying the full 10mg vial. View Bluum’s Ipamorelin page.

#4. American Peptides: 5mg and 10mg

Complete Ipamorelin spec sheet on-page. American Peptides puts almost everything a buyer checks on one screen: CAS, formula, weight, sequence, solubility, storage, a safety data sheet, and a COA for each size. Having it all in one place makes the paperwork quick to check.

• Sizes: 5mg and 10mg
• Listed price: $40 (5mg), $60 (10mg); volume pricing from 3 units
• Purity and identity testing: RP-HPLC purity with LC-MS/MS identity
• Latest COA on file: Bioviridian, lot IPA5-0803 (5mg), 99.78%, issued 17 August 2026
• Shipping: same-day before 12 pm CT, free over $300

The Bioviridian certificate adds endotoxin and heavy-metal results plus a web verification code.

The catch on our check date was stock: the 5mg showed as sold out, so smaller orders meant waiting or stepping up to 10mg. See American Peptides’ Ipamorelin.

#5. Thrive Peptides: 10mg

Batch-tested mg shown on listing. Thrive Peptides prints its batch data next to the buy button: batch TP-02-IPA, tested at 12.01 mg and 99.906% purity. That puts a measured quantity in front of you before you add the vial to your cart.

• Sizes: 10mg only
• Listed price: $34.99 sale ($44.99 regular)
• Purity and identity testing: batch purity and tested quantity shown on the listing
• Latest COA on file: batch TP-02-IPA results printed on the listing
• Shipping: ships same day, free 2-business-day shipping over $200; all sales final

One detail is worth confirming with support before you order: the spec line says 10mg, while the description calls it “supplied as a 5mg lyophilized peptide.” Asking for the TP-02-IPA certificate settles both the size and the batch in one reply. Browse Thrive’s Ipamorelin.

Why Ipamorelin Prices Differ Between Suppliers

Across these five listings, a vial of Ipamorelin runs from about $35 to $110. The gap comes mainly from vial size, testing depth, and shipping terms. Compare those three before you compare dollars, and the spread starts to make sense.

Vial size changes the apparent price

A 10mg vial costs more than a 5mg vial and usually less per milligram. Divide the price by the milligrams before you judge anything.

Member and promotional rates sit outside the per-mg column. Kylo, for example, sells a one-time membership that discounts its catalog.

Testing can change what is included in the listed price

Each step up the testing ladder costs the supplier more:

• Purity claimed: a sentence on a web page
• HPLC result: a number from a lab
• HPLC + MS: proof the main peak is Ipamorelin
• Lot-specific, third-party COA: all of it tied to your batch
• Extra panels: endotoxin, sterility, or heavy metals on top

Shipping and order thresholds affect the final cost

Free-shipping lines run from $150 (Kylo) to $300 (American Peptides), so a single $50 vial can cost more once shipping lands. Dispatch speed, quantity tiers, and coupon codes also move the final number. Price the whole cart.

The Ipamorelin COA Is More Important Than the Product Listing

Think of the certificate of analysis as the receipt for what sits inside the vial. A product listing can say almost anything. A certificate names a lab, a lot, a test date, and a result you can verify yourself, so it deserves more attention.

Match the COA to the vial

Line these up before you trust a certificate:

• Lot or batch number (same on vial and COA)
• Product name and vial size
• Test date
• Laboratory name
• Report or sample number

What should appear on an Ipamorelin COA?

A useful certificate shows identity (usually by mass spectrometry), Ipamorelin purity by HPLC, and appearance. Better ones also include measured quantity, such as the content figures on American Peptides and Kylo certificates. Add extra analytical tests, such as endotoxin or heavy metals, and full lab contact details to round it out.

Published COA vs. generic certificate

A generic certificate proves that some batch once tested well. A lot-specific document tells you about the batch you’re actually holding. Only the second one helps you judge a particular vial.

Kylo’s library, for example, lists each certificate by lot and sample number.

What if the COA cannot be verified?

Work through this checklist:

1. Ask support for the document that matches your lot.
2. Compare the product name and lot number on the vial and COA.
3. Check that the testing lab exists and can be contacted.
4. Read the actual numbers, including the chromatogram if shown.

Ipamorelin Product Differences That Matter Before Ordering

Settle these three product questions right away: which vial size fits the study, whether you need the single compound or a blend, and which partner compound sits inside a blend. Each answer changes what you’re buying and how you compare prices.

5mg vs. 10mg Ipamorelin

An Ipamorelin 5mg vial suits a small pilot study and costs less up front. An Ipamorelin 10mg vial keeps more material under one lot so that a longer study can run on a single certificate. Availability varies too: Kylo and American Peptides list both sizes, while Biotech sells 5mg only and Bluum and Thrive sell 10mg only.

Individual Ipamorelin vs. peptide blends

A single-compound vial lets you control one variable at a time. With a blend, you can’t change one ingredient without changing the other.

Ipamorelin vs. Ipamorelin-containing blends

A CJC-1295 Ipamorelin blend is a common example. CJC-1295 works at a different receptor, GHRH-R, so a blend mixes two mechanisms in one vial.

Kylo lists standalone Ipamorelin and a CJC-1295 + Ipamorelin blend separately, and Bluum lists a Tesamorelin/Ipamorelin blend at 10mg/2mg. Check which one you’re ordering.

How to Evaluate an Ipamorelin Supplier Before You Buy

To vet a research peptide source before checkout, use what we call the Paper-Trail Test. Every claim on the listing should lead to a document, and every document should lead back to your vial. If the trail breaks at any step, pause before you pay.

Start with product transparency.

The listing should state:

• Compound name and CAS number
• Molecular weight and sequence
• Vial size and physical form
• Research-use status

Follow the testing trail

Look for a named method, a named lab, a lot number, a test date, the actual results, and a COA you can open. Missing any one of these weakens the chain. Some labs, such as Bioviridian, also print code you can check on their own site.

Check whether the supplier distinguishes research products from human-use products

Clear research-only labeling is the baseline. A listing that slips into treatment language, dosing tips, or “benefits” is telling you how it expects the product to be used.

Check ordering information before comparing prices

Review shipping cost and speed, the return or refund policy, stock status, quantity discounts, contact details, and how you’ll get the COA. Weigh the refund terms and how quickly support answers alongside the sticker price.

What Should You Check Before Buying Ipamorelin Peptide?

Before placing an Ipamorelin order, run through the fourteen checks below. They cover identity, quantity, testing, paperwork, pricing, and the supplier itself. Tick each one against the listing and the COA, and you’ll catch most problems before they reach your bench.

If a listing fails two or more of these checks, ask the supplier for the missing document first. A good source answers with a PDF that matches the request.

Ipamorelin Storage and Product Handling Information

Lyophilized Ipamorelin keeps best cold, dark, dry, and sealed in its original vial until you need it. Kylo, Bluum, and American Peptides each publish storage temperatures on their own listings, and the figures below come straight from those three pages.

Lyophilized Ipamorelin storage

• Temperature: Kylo and American Peptides say −20 °C; Kylo prefers −80 °C for long-term storage
• Short term: Bluum lists 2- 8 °C, dry and dark, with −20 °C or below long term
• Light and moisture: Kylo says store cold, protect from light, and keep dry

Why the supplier’s documentation matters

Kylo and Bluum publish storage guidance for the same molecule, and their temperatures don’t line up exactly. Each maker knows its own fill, stopper, and cake. Follow the conditions supplied with your material over a one-size rule from a forum.

Research Context: What Scientists Study With Ipamorelin

In the lab, Ipamorelin works mostly as a receptor tool. Current studies cover GHSR-1a signaling, growth hormone release in rat pituitary cells, hormone selectivity in swine, and bone and gut models in rodents. More human trials are needed before we can conclude.

GHSR-1a receptor research

Labs use Ipamorelin to switch on GHSR-1a and trace what follows. Raun’s team showed it acts through a GHRP-like receptor, as GHRP-6 does.

Growth hormone secretagogue signaling

In rat pituitary cells, it released GH about as potently as GHRP-6 (EC50 1.3 vs 2.2 nmol/L).

Receptor selectivity studies

In swine, GHRP-6 and GHRP-2 raised ACTH and cortisol. Ipamorelin did not, even above 200 times its ED50, and none of the three moved FSH, LH, prolactin, or TSH.

Neuroendocrine signaling models

Ghrelin signaling reaches past the pituitary, so rodent work followed it into bone and gut: longitudinal bone growth in rats and a postoperative ileus model.

Comparative secretagogue research

Raun’s team also profiled GHRP-2, which showed higher potency but lower efficacy in swine.

Ipamorelin vs. Other Research Compounds in the Same Research Area

Ipamorelin shares the growth-hormone axis with CJC-1295, GHRP-6, and Sermorelin. CJC-1295 and Sermorelin act at the GHRH receptor, a separate route from Ipamorelin’s. GHRP-6 shares Ipamorelin’s receptor family with a broader hormone profile, so each compound answers a different research question.

That receptor split is also why CJC-1295 and Ipamorelin often appear together in blends, with each compound working its own receptor.

Common Problems to Watch for When Buying Research Ipamorelin

Sourcing mistakes usually come from trusting one line on a product page. A purity badge, a lab logo, or a low price can hide a missing lot number. These seven red flags show up again and again on supplier pages.

A “99% purity” claim with no supporting report

Ask which lab produced the figure and on what date. A number you can’t trace to a report says nothing about the lot in your cart.

COA that does not identify the tested lot

Ask for the lot-specific version before you pay. Without a lot line, one certificate can sit on a listing through several batches.

Product page missing basic chemical information

Without a CAS number or sequence, it’s hard to tell plain Ipamorelin from a blend or a different salt form.

Unclear testing laboratory

Look for a lab address or a verification page. Horizon Analytical, which tests Bluum’s lots, says its reports are searchable on its site.

Research product marketed with human-use claims

“Protocol” pages or before-and-after wording show which buyer the page is written for.

Confusing an individual peptide with a blend

A blend’s milligram figure can cover two compounds. A vial labeled 10mg/2mg holds 12mg of peptide, and only one part of that split is Ipamorelin, so read the label closely.

Comparing prices without comparing vial quantities

A $50 5mg vial and a $70 10mg vial look close on the page. Per milligram, one costs $10 and the other $7.

Understanding the Research-Only Status of Ipamorelin

Ipamorelin sold online is laboratory research material meant for in vitro and preclinical work. It isn’t an approved drug, and a research supplier isn’t a pharmacy or a clinic, so nothing on its product pages counts as medical guidance.

A clear listing says so plainly: it names the compound, states the research-only status, and avoids any talk of treatment.

The FDA lists Ipamorelin acetate among bulk drug substances that may pose safety risks in compounding. It cites immunogenicity concerns and a published report of serious adverse events, including death, after intravenous use in a gut-motility study. For some other injectable routes, it says it lacks enough information to judge safety.

Human-use, treatment, dosing, and administration questions sit outside research purchasing. Researchers remain responsible for following their institutional and legal requirements.

Frequently Asked Questions About Buying Ipamorelin

Is Ipamorelin the same as Ipamorelin acetate?

Yes. “Acetate” names the salt it’s supplied as, and Bluum lists both names. The salt adds weight without changing the sequence, so the COA should name the form it tested.

Why do Ipamorelin listings show different molecular weights?

Mostly rounding: 711.85, 711.86, and ~711.9 g/mol. Biotech’s MS report uses a monoisotopic mass of 711.38 Da, a different measure than the average weight on a shop page.

Does every Ipamorelin COA test the same things?

No. Biotech’s sheet covers purity and mass, and American Peptides’ report adds content, endotoxin, and heavy metals. Kylo’s Optiq report adds sterility, residual solvents, yeast and mold, pH, and water activity.

Why can two Ipamorelin products with similar purity have different prices?

Purity is one line of the cost. Every extra lab panel adds a fee, and sales, coupons, or member pricing move the sticker price. Two vials near 99% can come with very different paperwork.

Can an Ipamorelin COA from one batch be used to verify another batch?

No. A certificate describes only the sample the lab received, and Optiq’s Ipamorelin report says so in its fine print. Bluum lists its current lot beside a prior one (IPA102606-86A, 99.95%), so read the lot line before the headline figure.

Final Thoughts on Buying Ipamorelin Peptide

Several suppliers sell Ipamorelin in different vial sizes and at very different prices. Price alone won’t tell you much. Check identity, purity, testing, the lot number, and the COA, then weigh cost per milligram and confirm the listing names the single compound.

Run the checklist against each listing and its certificate, and the right fit for your study usually becomes clear. Choose the source whose documentation matches your research plan. If you want both sizes and a full lot panel, visit Kylo’s Ipamorelin page and compare its certificate first.
