Ipamorelin

CAS: 170851-70-4

Ipamorelin is a research peptide in the growth hormone / gh secretagogues category. Ipamorelin is a highly selective growth hormone secretagogue that acts on the ghrelin/GHS receptor (GHSR) in the pituitary to stimulate pulsatile GH release. MiPeptidos offers Ipamorelin in 3 sizes with 99.7% verified purity and full analytical documentation.

How Ipamorelin Works

Ipamorelin is a highly selective growth hormone secretagogue that acts on the ghrelin/GHS receptor (GHSR) in the pituitary to stimulate pulsatile GH release. Unlike other GHRPs, ipamorelin does not significantly affect cortisol, ACTH, or prolactin levels at GH-releasing doses, making it the most selective GHS available. It works synergistically with GHRH analogs (like CJC-1295) to amplify GH pulses while maintaining the natural pulsatile release pattern.

Research Applications

Reconstitution Calculator

Add this much bacteriostatic water:
2.0 mL
2 mg Ipamorelin + 2.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Frequently Asked Questions

Ipamorelin (CAS: 170851-70-4) is a research compound, with a molecular weight of 711.85 Da in the Growth Hormone / GH Secretagogues category. Ipamorelin is a highly selective growth hormone secretagogue that acts on the ghrelin/GHS receptor (GHSR) in the pituitary to stimulate pulsatile GH release. Unlike other GHRPs, ipamorelin does not significantly affect cortisol, ACTH, or prolactin levels at GH-releasing doses, making it the most selective GHS available. Researchers commonly investigate Ipamorelin for Selective GH secretion without cortisol elevation, Synergistic combination with GHRH analogs, Bone density and growth studies. Every vial from MiPeptidos includes batch-specific analytical documentation.
Ipamorelin is available in 3 sizes (2mg, 5mg, 10mg), so reconstitution volume depends on which vial you have. For the 2mg size, add 1mL of bacteriostatic water; for the 10mg size, use 2-3mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted Ipamorelin at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
Ipamorelin is the most selective ghrelin receptor (GHSR-1a) agonist available — it stimulates GH release without elevating cortisol, prolactin, or appetite, unlike GHRP-2 (which raises cortisol and prolactin) and GHRP-6 (which strongly stimulates appetite via ghrelin mimicry). At just 711.85 Da, Ipamorelin is a pentapeptide with clean, targeted GH pulsatility. This selectivity makes it the preferred GHRP for researchers wanting to isolate GH effects from hormonal side-pathways. MiPeptidos carries all three GHRPs for comparison studies.
Store lyophilized Ipamorelin at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Ipamorelin has a reported half-life of ~2 hours, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Ipamorelin order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-PMRL-2600215, tested February 27, 2026) shows 99.7% purity by HPLC, mass spectrometry confirmation at 711.85 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
