Ipamorelin
Highly selective pentapeptide GH secretagogue — triggers a clean GH pulse with minimal cortisol or prolactin co-stimulation.
01 · What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide and one of the most selective growth hormone secretagogues studied. It triggers GH release via the ghrelin receptor (GHSR-1a) with minimal co-stimulation of ACTH, cortisol, or prolactin — a cleaner profile than older GHRP-class peptides. Originally developed by Novo Nordisk, it reached Phase II clinical trials (as ulimorelin/TZP-101) for gastrointestinal motility. It is commonly sold alone and in the CJC-1295 + Ipamorelin blend.
Sizes currently sold by tracked vendors: 100mg, 10MG, 10mg, 11.76mg, 12mg, 200mg, 20mg, 2mg, 50mg, 5mg.

04 · Frequently asked questions
What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide and one of the most selective growth hormone secretagogues studied. It triggers GH release via the ghrelin receptor (GHSR-1a) with minimal co-stimulation of ACTH, cortisol, or prolactin — a cleaner profile than older GHRP-class peptides.
Is Ipamorelin FDA approved?
No. Ipamorelin is not FDA-approved. It completed Phase II trials for GI motility (as ulimorelin) but was never approved, and research-grade material is a laboratory reagent.
Sources: ClinicalTrials.gov — ulimorelin ↗ · checked Sep 24, 2026
Has Ipamorelin been tested in humans?
Yes — under the name ulimorelin (TZP-101) it reached Phase II human trials for postoperative ileus and diabetic gastroparesis, where it showed prokinetic activity but was never approved for any indication. Those trials studied the ghrelin-receptor pathway, not growth-hormone endpoints.
Sources: Phase 2b colectomy trial (PubMed) ↗ · checked Sep 24, 2026
Why is Ipamorelin paired with CJC-1295?
They stimulate GH release through two different receptor pathways — CJC-1295 via GHRH receptors, Ipamorelin via the ghrelin/GHSR-1a receptor — so the combination produces a larger GH response than either alone. This is why the CJC + Ipa blend is one of the most common stack products.
How much does Ipamorelin cost?
Across 39 vendors tracked by PepVendors, Ipamorelin currently runs $0.65–$22.59 per mg at each vendor's best price tier (39 showing in stock). Vial prices and size tiers vary — the live comparison table on this page lists current pricing.
