Storage & reconstitution

Before opening

Lyophilised powder is stable at ambient temperature in transit. On arrival, keep sealed vials refrigerated at 2–8 °C, dry and dark. For storage beyond three months, keep at −20 °C.

Reconstitution

Follow your laboratory's own protocol.

After reconstitution

Refrigerate at 2–8 °C and protect from light. Use within 30 days. Discard if the solution becomes cloudy or discoloured.

For laboratory research use only. Not for human or veterinary consumption. Not a drug or dietary supplement.

Research record

Three characterised lines of work

Ipamorelin is a pentapeptide growth hormone secretagogue. In animal studies it stimulates the pituitary gland to release growth hormone, and it has been observed to reduce somatostatin, a secretion that inhibits growth hormone release. Work on the growth hormone axis also describes changes in IGF-1 (insulin-like growth factor 1) downstream of that release.

01

Secretagogue receptor route

The original characterisation describes a pentapeptide identified within a series of compounds lacking the central Ala-Trp dipeptide of GHRP-1. In primary rat pituitary cells it released growth hormone with potency and efficacy reported as similar to GHRP-6, at an EC50 of 1.3 nmol/l against 2.2 nmol/l. Profiling with GHRP and GHRH antagonists indicated that release proceeds through a GHRP-like receptor rather than the GHRH receptor, which is the basis on which the compound is separated from the GHRH analogues sold alongside it.

02

Potency across species

The same report describes dose-response work in two animal models: in pentobarbital-anaesthetised rats an ED50 of 80 nmol/kg with a maximum of 1545 ng growth hormone per ml, and in conscious swine an ED50 of 2.3 nmol/kg with a maximum of 65 ng/ml plasma. Both are given against GHRP-6 measured in parallel, and both are reported as comparable to it.

03

Later receptor-level work

A 2024 study examined two growth hormone secretagogue receptor 1a agonists in ferrets given cisplatin, reporting that both anamorelin and ipamorelin inhibited the weight loss and reduced feeding seen in acute and delayed phases. The anti-emetic effect described in that work is attributed to anamorelin alone and to a central mechanism, with the two compounds also compared on electrically stimulated contractions of isolated ileum.

The characterisation this record rests on is preclinical and dates to 1998, in rat pituitary cells and in two animal species. A 2020 review of growth hormone secretagogues in the management of body composition states that clinical efficacy data for this class largely remain lacking, and a 2026 review of peptides used in sports medicine catalogues the compound among those marketed to patients without regulatory approval. The compound holds no FDA approval.

Common questions

Ordering, handling and compliance. Anything not covered here, write to support@pureforgelabs.com.

What does research use only actually mean?

Every compound we sell is supplied for laboratory research and development only. It is not a drug, not a supplement, and not intended to diagnose, treat, cure or prevent any condition in humans or animals. Buying from this site means you are acquiring it for in vitro or other controlled research work.

Who is allowed to order?

Purchasers must be 21 or older and are responsible for compliance with the law where they take delivery. We ship to research institutions, laboratories and qualified individual researchers in the United States only. We do not ship to jurisdictions where these compounds are restricted.

How do I read the certificate of analysis?

Check three things in order. First, the lot code on the certificate matches the lot listed on the product page and in your order. Second, where the report gives an HPLC purity, its chromatogram shows a single dominant peak at the stated figure; a blend's report shows a peak for each compound. Third, where the lab ran mass spectrometry, the measured mass matches the expected molecular weight of the compound. Anything that does not line up, send us the lot code.

How should it be stored?

Unopened vials keep at ambient temperature short term, as in transit; on arrival, refrigerate them at 2–8 °C, and keep them at −20 °C beyond three months. Reconstitute following your laboratory's own protocol; once in solution, refrigerate at 2–8 °C, protect from light and use within 30 days.

When does it ship and how?

Orders are normally prepared for shipment within 1–3 business days and ship to street addresses in the United States only — not to P.O. boxes or APO/FPO/DPO military addresses. Shipping is free on orders over $150 and a flat $14.95 below that.

What payment methods do you take?

We take credit and debit cards, paid securely at checkout. Bank transfers and purchase orders are not available at the moment.

What if a vial arrives damaged?

Keep the vial and all the packaging, photograph the damage and email support@pureforgelabs.com within 48 hours of delivery with your order number. Once the claim is verified, we replace the vial or refund what you paid for it. Please do not send anything back unless we ask you to — apart from damaged or incorrect items, all sales are final.

Do you handle bulk and wholesale orders?

Yes, by quote. The volume tiers on the product pages go up to five vials; for larger research quantities email support@pureforgelabs.com with the compounds and amounts, and we will quote per gram.
