Hormone & Growth
Peptides studied for their influence on growth hormone secretion, gonadotropin signaling, and endocrine axis modulation in preclinical research models.
Amplifies your natural growth hormone pulses — builds lean muscle, burns fat, deepens sleep, and makes your skin look younger.
- Boosts natural growth hormone for muscle building and fat loss
- Improves deep sleep quality and recovery
The king of growth hormone stacks — packs on lean muscle, strips fat, deepens sleep, and tightens skin without the cortisol spike or hunger.
- The gold standard GH stack — maximum muscle growth and fat loss
- Deep, restorative sleep from the first use
Ipamorelin
10mgThe cleanest growth hormone booster — releases GH without the hunger, bloating, or cortisol crash of other peptides. Pure muscle-building, fat-burning signal.
- Clean growth hormone release without hunger spikes or cortisol
- Builds lean muscle and accelerates fat burning
GHRP-6
5mgThe mass-builder's GH peptide — triggers the strongest growth hormone release available, drives appetite for serious bulking, and protects joints under heavy loads.
- Strongest growth hormone release of any GH peptide
- Dramatically increases appetite — ideal for building mass
GLP-3 R
10mgNext-gen metabolic research beyond semaglutide — targets novel receptor pathways in the incretin system for advanced metabolic studies.
- Next-generation metabolic signaling beyond GLP-1
- Advanced incretin biology research compound
Kisspeptin
5mgThe master switch of your sex hormones — triggers the full cascade from brain to testosterone/estrogen production, boosting libido, arousal, and fertility in both sexes.
- Triggers the hormonal cascade that drives sex drive and arousal
- Boosts testosterone in men and estrogen in women naturally
PT-141
10mgThe sex drive peptide — works directly in your brain to ignite genuine sexual desire and arousal in both men and women. FDA-approved mechanism. This is the one everyone's talking about.
- Directly increases sexual desire and arousal in both men AND women
- Works through the brain — not blood flow — for genuine desire, not just mechanics
Testagen
20mgNatural testosterone support — regulates the pituitary signals that control T production, supporting healthy libido, energy, and masculine drive without shutdown.
- Supports natural testosterone production without shutdown
- Regulates the pituitary signals that control T levels
Sermorelin
5mgThe gentle GH booster — stimulates your pituitary to produce its own growth hormone naturally, improving muscle tone, fat loss, sleep quality, and recovery.
- Stimulates your body's own growth hormone production naturally
- Improves body composition — more muscle, less fat
Tesamorelin 10mg
10mgFDA-approved belly fat destroyer — the only growth hormone analog specifically approved to eliminate dangerous visceral fat while preserving lean muscle mass.
- FDA-approved to reduce visceral belly fat
- Specifically targets dangerous abdominal adipose tissue
About Hormone & Growth Research
The Hormone & Growth collection encompasses peptides under investigation for their roles in the somatotropic axis, hypothalamic-pituitary-gonadal axis, and broader endocrine signaling networks. This category includes growth hormone secretagogues such as CJC-1295, Ipamorelin, and GHRP-6, along with peptides like Kisspeptin and PT-141 studied for reproductive endocrinology and melanocortin receptor pathways. Testagen is included for its investigation in androgen-related gene expression. These peptides are essential tools for researchers studying hormonal regulation, growth factor biology, and neuroendocrine mechanisms.
