Body Protection Compound-157
The body's master repair peptide
BPC-157 is a synthetic peptide derived from a protein found in human gastric juice. It has become one of the most researched peptides in the biohacking community due to its remarkable regenerative and healing properties across multiple tissue types.
Dosage
200–500 mcg per day
Thymosin Beta-4 (synthetic fragment)
Systemic healing and tissue regeneration
TB-500 is a synthetic version of a naturally occurring peptide called Thymosin Beta-4, which is present in virtually all human and animal cells. It plays a critical role in building new blood vessels, muscle tissue, and skin.
Dosage
2–2.5 mg twice weekly (loading), then 2 mg monthly (maintenance)
Sermorelin Acetate (GHRH 1-29)
Natural growth hormone optimization
Sermorelin is a growth hormone-releasing hormone (GHRH) analogue that stimulates the pituitary gland to produce and secrete natural growth hormone. Unlike synthetic HGH, it works with your body's own feedback mechanisms.
Dosage
200–500 mcg before bed
Ipamorelin (Growth Hormone Secretagogue)
Clean GH release with minimal side effects
Ipamorelin is a selective growth hormone secretagogue and ghrelin mimetic. It is widely regarded as one of the cleanest GH-releasing peptides available due to its high selectivity — it stimulates GH release without significantly increasing cortisol or prolactin.
Dosage
200–300 mcg, 2–3x daily or before bed
CJC-1295 (with or without DAC)
Sustained GH elevation for body recomposition
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH). The DAC (Drug Affinity Complex) version has an extended half-life of up to two weeks, making it highly convenient for GH optimization protocols.
Dosage
1–2 mg per week (DAC version) or 100–200 mcg daily (no DAC)
Bremelanotide (PT-141)
Central nervous system sexual enhancement
PT-141 (Bremelanotide) is a melanocortin receptor agonist that works directly on the central nervous system to enhance sexual desire and arousal. Unlike PDE5 inhibitors, it acts on the brain rather than the vascular system.
Dosage
0.5–2 mg, 45–60 minutes before sexual activity
Melanotan II (MT-2)
Tan, libido, and appetite control
Melanotan II is a synthetic analogue of the naturally occurring alpha-melanocyte-stimulating hormone (α-MSH). It is widely used for its ability to stimulate melanin production, producing a deep, natural-looking tan without UV exposure.
Dosage
0.5–1 mg per day (loading), then 0.5 mg maintenance
Copper Peptide GHK-Cu
Skin regeneration and anti-aging at the cellular level
GHK-Cu is a naturally occurring copper peptide found in human plasma, saliva, and urine. It is one of the most studied peptides for skin health and anti-aging, with a remarkable ability to stimulate collagen synthesis and skin regeneration.
Dosage
Topical: 1–5% concentration. Injectable: 1–2 mg/day
Epithalamin / Epitalon
Telomere extension and cellular longevity
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide based on the natural peptide Epithalamin, extracted from the pineal gland. It is one of the most researched longevity peptides, with studies showing it can extend telomere length and lifespan in animal models.
Dosage
5–10 mg per day for 10–20 day cycles, 1–2x per year
Selank (Tuftsin analogue)
Anxiolytic nootropic for calm, focused performance
Selank is a synthetic analogue of the immunomodulatory peptide Tuftsin. Developed in Russia, it is used clinically as an anxiolytic (anti-anxiety) agent and nootropic, offering the calming effects of benzodiazepines without the addiction potential.
Dosage
250–3000 mcg per day
Semax (ACTH 4-7 Pro8Gly9Pro10)
Cognitive enhancement and neuroprotection
Semax is a synthetic peptide analogue of ACTH (adrenocorticotropic hormone) developed in Russia. It is one of the most potent nootropic peptides available, with strong effects on cognition, focus, and neuroprotection.
Dosage
200–900 mcg per day
Kisspeptin-10 (KP-10)
Testosterone and LH pulse optimization
Kisspeptin-10 is a fragment of the kisspeptin protein that plays a critical role in regulating the hypothalamic-pituitary-gonadal (HPG) axis. It is a potent stimulator of LH and FSH release, making it valuable for testosterone optimization.
Dosage
50–100 mcg, 1–2x daily
