What is GHRP-2?
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates the ghrelin receptor (GHS-R) to trigger pulsatile release of growth hormone from the anterior pituitary. It is one of the most potent and well-studied GHRPs available, producing significant GH spikes in research models. Unlike ipamorelin, GHRP-2 also modestly increases cortisol and prolactin, which is a relevant variable in comparative peptide research.
VELTRIDE supplies GHRP-2 5mg lyophilized powder verified at ≥98% purity by HPLC, with a Certificate of Analysis included. It ships discreetly across Canada from our West Kelowna, BC facility. GHRP-2 is widely used alongside GHRH peptides like CJC-1295 to produce synergistic GH pulse amplification in research protocols.
Research Highlights
- One of the most potent GHRPs — produces strong GH pulses in vivo models
- Acts on ghrelin receptor (GHS-R1a) to stimulate pituitary GH secretion
- Studied for lean mass support and recovery acceleration
- Mild appetite stimulation observed — relevant for cachexia and wasting research
- Modest cortisol and prolactin elevation compared to GHRP-6
- Synergistic GH amplification when combined with GHRH analogues
- Half-life approximately 15-60 minutes — allows flexible dosing protocols
GHRP-2 vs Ipamorelin
GHRP-2 produces stronger GH pulses than Ipamorelin but also causes modest cortisol and prolactin elevation. Researchers choosing selectivity prefer ipamorelin; those wanting maximum GH output may select GHRP-2. Both stack effectively with CJC-1295 for amplified GH research.
