Side Effects
Expected pharmacological effect. Occurs within 30-60 minutes of injection. May be beneficial for those seeking to increase caloric intake but problematic for those on caloric restriction.
Mild erythema, swelling, or discomfort at injection site. Usually resolves within hours. Minimize by rotating injection sites, using room-temperature solution, and ensuring proper injection technique.
Reported in some users, typically mild and transient. May be related to GH secretion or individual sensitivity.
Transient vasodilation reported in some users. Usually resolves within 15-30 minutes of injection.
Reported rarely. Sit or lie down if experienced. Ensure adequate hydration.
Uncommon but reported by some users. Usually mild and transient. May be minimized by injecting on a full stomach.
Localized fat loss or thickening at repeated injection sites. Preventable through systematic site rotation. Rotate sites with each injection and avoid injecting into the same location more than once per week.
GH secretagogues may transiently elevate cortisol. Clinically significant elevation is rare with alexamorelin. Monitor if using chronically.
Minor prolactin elevation reported in some studies. Typically not clinically significant with short-term use.
Anaphylaxis or severe allergic reaction is rare but possible. Seek immediate medical attention if experiencing difficulty breathing, severe swelling, or chest pain. Discontinue use immediately.

Reconstitution Guide
Do not use saline or bacteriostatic saline — use only bacteriostatic water for reconstitution
Do not shake the vial vigorously; gentle swirling prevents peptide degradation
Discard immediately if the solution appears cloudy, discolored, or contains visible particles
Use within 30 days of reconstitution when stored at 2–8°C
Do not freeze the reconstituted solution; freezing may denature the peptide
Use the PeptideVolt reconstitution calculator for your exact concentration
Molecular and Pharmacological Data
Alexamorelin is a synthetic ghrelin receptor agonist that binds to the growth hormone secretagogue receptor 1a (GHS-R1a) on anterior pituitary somatotroph cells. This binding stimulates the release of growth hormone in a dose-dependent manner. Additionally, alexamorelin activates ghrelin signaling pathways in the hypothalamus and gastrointestinal tract, leading to increased appetite and food intake, similar to endogenous ghrelin.
GHS-R1a Receptor Activation
Alexamorelin acts as a selective agonist at the growth hormone secretagogue receptor 1a (GHS-R1a) on somatotroph cells in the anterior pituitary. This activation stimulates GH secretion through intracellular calcium mobilization and depolarization of somatotroph cells.
Appetite Stimulation
Ghrelin receptor activation in the hypothalamic arcuate nucleus stimulates neuropeptide Y (NPY) and agouti-related peptide (AgRP) neurons, which promote feeding behavior and increase appetite.
Metabolic Effects
GH secretion induced by alexamorelin promotes lipolysis, increases protein synthesis, and enhances glucose metabolism, contributing to changes in body composition.
- Alexamorelin is a non-peptide ghrelin mimetic (small molecule) that selectively activates GHS-R1a
- GH secretion occurs in a dose-dependent manner with peak response typically 30-60 minutes post-injection
- The peptide does not suppress somatostatin, allowing for sustained GH release
- Appetite stimulation is mediated through central ghrelin signaling pathways independent of GH secretion
- Alexamorelin demonstrates minimal tachyphylaxis with repeated dosing over short-term protocols
