RecoveryWell-Studied

BPC-157

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.

TB-500

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.

Systemic recoveryFlexibilityHair growth

Dosage

2–2.5 mg twice weekly (loading), then 2 mg monthly (maintenance)

Growth HormoneWell-Studied

Sermorelin

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.

Ipamorelin

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.

CJC-1295

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)

Sexual HealthWell-Studied

PT-141

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.

Libido enhancementErectile functionSexual confidence

Dosage

0.5–2 mg, 45–60 minutes before sexual activity

Melanotan II

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.

GHK-Cu

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.

LongevityEmerging

Epithalon

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.

LongevityAnti-agingSleep

Dosage

5–10 mg per day for 10–20 day cycles, 1–2x per year

CognitiveWell-Studied

Selank

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.

Semax

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.

Kisspeptin-10

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.
