What is the difference between GHRP-6 and Hexarelin?

GHRP-6 (Growth Hormone Releasing Peptide 6) is graded B and is Not FDA-approved — research compound. Hexarelin (Hexarelin (HEX)) is graded B and is Not FDA-approved — research compound (cardioprotective signals investigated). They are commonly compared because they share the categories: growth-hormone.

Which has stronger clinical evidence — GHRP-6 or Hexarelin?

On our internal evidence scale, GHRP-6 is B and Hexarelin is B. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of GHRP-6 vs Hexarelin?

GHRP-6: 100–300 mcg, 1–3 times daily (subcutaneous). Hexarelin: 100 mcg, 1–2 times daily (subcutaneous). Always work with a licensed clinician — peptide dosing should be individualized.

GHRP-6 vs Hexarelin

Both GHRP-6 and Hexarelin are used for growth-hormone. Here's how their evidence, dosing, and regulatory status actually compare.

GHRP-6

Evidence B

Growth Hormone Releasing Peptide 6

An older GHS that produces strong appetite stimulation in addition to GH release. Largely supplanted by Ipamorelin and GHRP-2 for clinical use but still common in research stacks.

Hexarelin

Evidence B

Hexarelin (HEX)

The strongest GH-releasing hexapeptide and one of the few peptides with documented direct cardiac benefits in animal models. Tachyphylaxis (diminished response over time) limits long-term use.
