What is the half-life of GHRP-2?

GHRP-2 has a half-life of Unknown, which is why it's typically administered As needed for optimal therapeutic effect.

How do I reconstitute GHRP-2?

Add bacteriostatic water to the peptide vial slowly down the side. Typical reconstitution uses 2-3ml of water for a 5mg vial. Gently swirl, do not shake.

GHRP-2

Also known as: Pralmorelin, KP-102, D-Ala-D-beta-Nal-Ala-Trp-D-Phe-Lys-NH2

Overview

Key Facts

Primary Goal: Research and therapeutic applications of GHRP-2

Potently agonizes the GHS-R1a receptor, producing the largest GH pulse among GHRPs. Stimulates hypothalamic GHRH neurons to amplify GH release.

8-16 weeks

Administration Routes:

subcutaneousintravenous

Benefits

Strongest GH release among GHRPs
Improved lean body mass and muscle recovery
Moderate appetite stimulation
Enhanced sleep quality
Potential neuroprotective effects

Side Effects

Moderate appetite increaseuncommonmild

Elevated cortisol and prolactin (less than GHRP-6)uncommonmild

Water retentionuncommonmild

Possible drowsinessuncommonmild

Tingling at injection siteuncommonmild

Mechanism of Action

Potently agonizes the GHS-R1a receptor, producing the largest GH pulse among GHRPs

Stimulates hypothalamic GHRH neurons to amplify GH release

Moderate ghrelin-like signaling increases appetite through NPY/AgRP pathway activation

Contraindications

Do not use this peptide if any of the following apply:

Active cancer or tumours
Pregnancy or breastfeeding
Conditions aggravated by elevated cortisol
Uncontrolled diabetes

Duration2-4 weeks

Note: Protect from light. Do not freeze reconstituted solution.

Research Summary

Preclinical

GHRP-2 (Pralmorelin) has been approved in Japan as a diagnostic agent for GH deficiency and extensively studied in clinical settings. Research demonstrates it produces the highest peak GH levels among GHRPs, approximately 20-40% greater than GHRP-6. Studies also suggest neuroprotective effects in models of neurodegeneration.
