What is the difference between Ipamorelin and Hexarelin?

Ipamorelin (Ipamorelin Acetate) is graded B and is Not FDA-approved — Category 1 (compounding allowed). 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 — Ipamorelin or Hexarelin?

On our internal evidence scale, Ipamorelin 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 Ipamorelin vs Hexarelin?

Ipamorelin: 100–300 mcg before bed (subcutaneous). Hexarelin: 100 mcg, 1–2 times daily (subcutaneous). Always work with a licensed clinician — peptide dosing should be individualized.

Ipamorelin vs Hexarelin

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

Ipamorelin

Evidence B

Ipamorelin Acetate

A selective growth hormone secretagogue that triggers GH release from the pituitary without significantly raising cortisol or prolactin. The safest GH peptide with the fewest side effects.

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.
