Ipamorelin is a synthetic pentapeptide. It has five amino acids. The sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH₂. So it’s a selective agonist at the ghrelin receptor (GHSR-1a).

It was originally developed by Novo Nordisk. First studied as a growth hormone secretagogue in the late 1990s. Researchers use Ipamorelin peptide because it stimulates GH release in a dose-dependent, pulsatile way. Also, it does not significantly increase ACTH, cortisol, or prolactin. That selectivity profile makes it a useful research compound.

However, this product is for laboratory research only. It is not approved for human use or therapeutic application.

Third-party testing is non-negotiable for credible research peptides. Therefore, we don’t just run in-house tests. Janoshik operates independently. Their report shows the purity percentage, identity confirmation, and lot number. Nothing is hidden.

Next, you can download the COA directly from the product page. No account required.

It ships as a white lyophilized (freeze-dried) powder. That form is stable and easy to handle in a lab. Also, it requires no special transport conditions short-term.

But storage matters a lot. Keep lyophilized Ipamorelin at −20°C in a sealed container. Moisture is the enemy  it degrades the peptide fast. So keep it dry. Stable for up to 4 years under proper conditions.

Once reconstituted in sterile water or bacteriostatic water, move it to 2–8°C. Use within 2–3 weeks. Finally, avoid repeated freeze-thaw cycles on the solution.

Good question. Several growth hormone releasing peptides exist. GHRP-2, GHRP-6, Hexarelin — all of them hit the same receptor. However, most also raise cortisol or prolactin at research doses.

Ipamorelin is different. It doesn’t significantly stimulate ACTH or cortisol. So researchers who want clean GH-related data often choose Ipamorelin. It also doesn’t spike hunger the way GHRP-6 tends to, which helps isolate variables.

Also, the ~2-hour plasma half-life is well-documented. That makes dosing windows in protocols predictable. Therefore, buy Ipamorelin when your study needs a selective, well-characterized GHSR-1a agonist with a clean side-effect profile in preclinical models.

First, purity. ≥99% confirmed by Janoshik, not claimed by us alone. The COA is public.

Next, consistency. Each batch is manufactured to the same spec  C₃₈H₄₉N₉O₅, 711.85 g/mol, lyophilized, no additives. You get the same product every time.

Also, speed. Orders dispatch fast. No long waits.

Finally, transparency. We show you the test results. We list the sequence, the CAS number, the storage conditions. No vague marketing. Just data.

So if you’re sourcing Ipamorelin for research, this is the straightforward option. No hype. Just verified peptide.
