Sermorelin & GHRP-2 & GHRP-6 vs Hexarelin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Sermorelin & GHRP-2 & GHRP-6

A powerful tri-blend combining Sermorelin (a GHRH analog) with two growth hormone releasing peptides. This combination produces significantly greater GH release than any single peptide, with studies showing up to 54-fold increases in pulsatile GH secretion.

Hexarelin

Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.

Side-by-Side Comparison

AspectSermorelin & GHRP-2 & GHRP-6Hexarelin
MechanismSermorelin stimulates the pituitary via GHRH receptors, while GHRP-2 and GHRP-6 act as ghrelin mimetics on different receptor subtypes. The combination creates synergistic GH release through multiple complementary pathways. GHRP-6 also strongly stimulates appetite.Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling.
Typical DosageTypical protocols: Sermorelin 100-300mcg, GHRP-2 100-300mcg, GHRP-6 100-300mcg. Often administered 2-3 times daily, 30 minutes before meals or at bedtime.Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization.
AdministrationSubcutaneous injection. Best administered fasted or before sleep to maximize natural GH cycle. The three peptides can be mixed together or administered separately.Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols.
Side EffectsIncreased hunger (especially from GHRP-6), water retention, facial flushing, nausea, tingling, potential increases in cortisol and prolactin levels.Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects.
