What is the difference between GHRP-2 and Sermorelin?

GHRP-2 (Growth Hormone Releasing Peptide 2) is graded B and is Not FDA-approved — research compound; previously studied as growth hormone deficiency diagnostic. Sermorelin (Sermorelin Acetate (GHRH 1-29)) is graded B+ and is FDA-approved (1990) for pediatric growth hormone deficiency; off-label adult use via compounding pharmacies. They are commonly compared because they share the categories: growth-hormone, anti-aging.

Which has stronger clinical evidence — GHRP-2 or Sermorelin?

On our internal evidence scale, GHRP-2 is B and Sermorelin is B+. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of GHRP-2 vs Sermorelin?

GHRP-2: 100–300 mcg, 1–3 times daily (subcutaneous). Sermorelin: 200–500 mcg before bed (subcutaneous). Always work with a licensed clinician — peptide dosing should be individualized.

GHRP-2 vs Sermorelin

Both GHRP-2 and Sermorelin are used for growth-hormone and anti-aging. Here's how their evidence, dosing, and regulatory status actually compare.

GHRP-2

Evidence B

Growth Hormone Releasing Peptide 2

A potent synthetic ghrelin-mimetic GH secretagogue. Drives strong GH spikes but raises cortisol and prolactin more than newer alternatives like Ipamorelin.

Sermorelin

Evidence B+

Sermorelin Acetate (GHRH 1-29)

The original synthetic GHRH(1–29) and the most accessible GH-stimulating peptide for age-related hormone decline. Stimulates the body's own pulsatile GH release rather than replacing it.
