Lean Muscle & Strength

Clean GH pulse — widely used for sleep, recovery, and lean composition.

Pre-clinical myostatin inhibitor — outsized muscle growth in animal models.

GHRH partner to Ipamorelin — together they amplify the GH pulse.

Long-acting IGF-1 analog — anabolic but raises systemic IGF-1 markedly.

The default 'GH stack' in a single vial — convenient, slightly less flexible.

Strongest GH-releasing peptide in the GHRP family.

Strong GH release with modest cortisol elevation — older but effective.

Clinical-grade myostatin pathway inhibitor — terminated in muscle dystrophy trials.

Pulsatile GHRH analog — pair with a GHRP for a clean GH pulse.

Hybrid SARM/myostatin inhibitor — strong anecdotal hypertrophy.

Long-acting GHRH analog dosed weekly, distinct from the no-DAC version.

Oral GH secretagogue with robust human data on GH and IGF-1 elevation.

Splice variant of IGF-1 that drives local muscle repair and growth.

Pegylated, longer-acting MGF for systemic muscle-repair signaling.

Ultra-potent short-acting IGF-1 variant for localized hypertrophy.

Oral GH secretagogue approved as an adult GH-deficiency diagnostic.

Early GHRP-family secretagogue, less common than GHRP-2 and 6.

Recombinant human growth hormone itself, the molecule the secretagogues chase.

Orally active GH secretagogue from early clinical research.

Antibody that builds muscle while cutting fat, a recomposition play.

Mimics LH to maintain testicular function, common in TRT protocols.

Selective estrogen modulator that raises natural testosterone.

Gut metabolite that triggers mitophagy, with human muscle-function data.

Locally acting follistatin-based agent for targeted muscle growth.

Circulating follistatin isoform variant of the 344 form.

GHRP with strong appetite stimulation — niche tool for hard-gainers.

The original clinical GHRH analog — gentle, well-tolerated GH support.

The visceral-fat peptide — FDA-approved for HIV-associated lipodystrophy.

Mild SARM — sometimes grouped with peptides in research catalogs.
