Filter by category, search by name. Each profile is graded on a five-tier evidence scale.
GHRH(1-29) / Geref
The original FDA-approved GHRH analogue. Stimulates natural GH production through your own pituitary gland. Most natural approach to growth hormone optimization available.
Egrifta / Stabilized GHRH / GHRH analogue
The most clinically validated GHRH analogue available. FDA-approved for visceral fat reduction. Emerging data for cognitive protection in early Alzheimer's and MCI. Widely prescribed off-label for body composition and longevity.
Growth Hormone Secretagogue (selective)
The most selective GH secretagogue available. Stimulates strong growth hormone release with minimal cortisol or prolactin side effects. Considered the gold standard secretagogue.
CJC-Ipa / GH Stack / Secretagogue Combination
The most commonly prescribed GH secretagogue combination in US longevity medicine. CJC-1295 provides GHRH stimulation while Ipamorelin provides ghrelin receptor stimulation — two complementary pathways for natural GH optimization.
Growth Hormone Secretagogue (selective) / GHS
The most selective growth hormone secretagogue available. Stimulates strong GH release with minimal cortisol or prolactin side effects. Gold standard for GH axis optimization.
Growth Hormone Releasing Peptide-2 / Pralmorelin
Potent GH secretagogue with stronger GH pulse than Ipamorelin but significant cortisol and prolactin elevation. Largely replaced by Ipamorelin in clinical settings.
Growth Hormone Releasing Peptide-6
Early GH secretagogue notable for strong appetite stimulation via ghrelin pathway. Studied for cachexia and muscle wasting. Also has gastroprotective properties similar to BPC-157.
Insulin-like Growth Factor-1 Long R3
Modified IGF-1 with 3x longer half-life. Directly stimulates muscle protein synthesis and satellite cell activation independent of the GH axis. Significant cancer risk concern.
FST-344 / Myostatin Inhibitor
Myostatin inhibitor studied for exceptional muscle growth by blocking the body's natural muscle-growth limiter. Dramatic animal model results. Significant organ growth safety concerns.
GnRH / Luteinizing Hormone-Releasing Hormone / Lutrepulse
FDA-approved GnRH analogue. Maintains testicular function and fertility during testosterone replacement therapy. Standard component of TRT protocols to prevent testicular atrophy.
KP-10 / Metastin fragment
Hypothalamic peptide that drives GnRH pulsatility — the most upstream signal in the entire reproductive hormone cascade. Studied for libido fertility and hypogonadism research.
