Ipamorelin 10mg
Selective pentapeptide ghrelin receptor agonist investigated for targeted, pulsatile growth hormone secretion without significant cortisol spikes.
Mechanism
Ipamorelin selectively binds to and activates the pituitary ghrelin receptor (GHS-R1a), triggering intracellular signaling cascades that provoke transient, pulsatile endogenous growth hormone secretion with negligible influence on cortisol or prolactin.
Dosing
Common experimental protocols establish an introductory research dose of 100 mcg administered once daily, typically titrated upward across an 8- to 12-week study framework.
Reconstitution
Diluting the 10 mg lyophilized vial with 3.0 mL of bacteriostatic water yields an operational working concentration of approximately 3.33 mg/mL (3,333 mcg/mL).
Storage
Store the lyophilized peptide at 2–8 °C for short-term preservation or at -20 °C for extended stability; keep the reconstituted liquid refrigerated at 2–8 °C and protected from light, never allowing it to freeze.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–2 | 100 mcg (1× daily) | ~3 units (0.03 mL) |
| Weeks 3–4 | 150 mcg (1× daily) | ~4.5 units (0.045 mL) |
| Weeks 5–8 | 200 mcg (1× daily) | ~6 units (0.06 mL) |
| Weeks 9–12 | 300 mcg (1× daily) | ~9 units (0.09 mL) |
Reconstitution Steps
- 1
Aseptically withdraw 3.0 mL of bacteriostatic water using a sterile syringe.
- 2
Slowly introduce the diluent into the vial, directing the stream against the interior glass wall to minimize turbulent agitation and foaming.
- 3
Gently rotate or swirl the vial until the lyophilized cake fully dissolves, taking care not to shake vigorously.
- 4
Record the preparation date and resulting concentration (~3.33 mg/mL) on the vial label, and immediately store refrigerated at 2–8 °C away from light.

Overview
Ipamorelin is an engineered synthetic pentapeptide designed to act as an agonist at the growth hormone secretagogue receptor (GHS-R1a). It emerged as an advanced generation secretagogue intended to provoke somatotroph cells within the anterior pituitary to release native growth hormone. Unlike older secretagogues like GHRP-6 or GHRP-2, ipamorelin's primary scientific distinction is its high specificity, producing negligible elevations in adrenocorticotropic hormone (ACTH), cortisol, or prolactin levels. Preclinical investigations frequently focus on ipamorelin's pharmacokinetic profile, which features a rapid peak and a systemic half-life of roughly two hours, thereby preserving natural episodic endocrine pulsatility rather than causing continuous systemic exposure. Research often explores its interactions alongside growth hormone-releasing hormone (GHRH) analogs to examine potential additive or synergistic somatotropic signaling pathways. Although explored clinically in preliminary trials for indications like postoperative ileus, ipamorelin did not meet critical endpoints and holds no regulatory approval for human administration or therapeutic application. Consequently, it remains strictly a non-clinical laboratory tool restricted to in vitro and animal experimental research.
