100–500 mcg · Once daily (30–60 min before bed)

Humanin is a mitochondria-derived peptide encoded in the 16S rRNA of mitochondrial DNA. It plays a protective role in aging, neurodegeneration, and metabolic disease — with levels shown to correlate with longevity in centenarian families.

100–500 mcg · 3–5x per week

Pinealon is a short tripeptide (Glu-Asp-Arg) developed in Russia alongside Epithalon. It penetrates the blood-brain barrier and acts as a DNA-targeting neuroprotective agent, shown to extend lifespan and protect neurons in aged animals.

500–2000 mcg · Once daily

Selank is a synthetic heptapeptide developed in Russia, approved there as an anxiolytic and nootropic. It reduces anxiety without sedation and enhances cognition — often described as a 'calm focus' compound without the downsides of benzodiazepines.

250–1500 mcg · 1–3x daily

A complementary nootropic blend pairing Selank's anxiolytic and GABA-modulating effects with Semax's BDNF-boosting cognitive enhancement. Together they create a balanced nootropic — Selank calms anxiety and stabilizes mood while Semax sharpens focus and drives neuroprotection. Popular in the Russian biohacking community as a daily cognitive stack.

250–500 mcg · Once to twice daily

Semax is a synthetic ACTH analog developed in Russia with powerful neuroprotective and cognitive enhancing effects. It significantly upregulates BDNF (brain-derived neurotrophic factor) — sometimes described as giving the effects of intense exercise on the brain.

200–900 mcg · 1–2x daily

SS-31 (Elamipretide) is a mitochondria-targeting peptide that concentrates in the inner mitochondrial membrane to protect cardiolipin and reduce reactive oxygen species. It's one of the most exciting longevity compounds showing reversal of mitochondrial aging.

1–5 mg · Daily to 3x weekly

VIP is a 28 amino acid neuropeptide with potent anti-inflammatory, immunomodulatory, and neuroprotective effects. It plays a key role in regulating immune response, gut motility, and pulmonary function. Most recognized in the context of Shoemaker Protocol for CIRS (Chronic Inflammatory Response Syndrome) and mast cell activation syndrome (MCAS), where VIP nasal spray is used as the final step in biotoxin illness recovery.

50–100 mcg · 4x daily (nasal) or once daily (SubQ)

A SERM that is FDA-approved for female infertility and used off-label in men to raise natural testosterone, and in performance circles for post-cycle recovery. It is a mix of the enclomiphene and zuclomiphene isomers.

25–50 mg · Daily or every other day

The trans-isomer of clomiphene, a selective estrogen receptor modulator (SERM) that raises natural testosterone by increasing LH and FSH without shutting down the testicular axis. Favored by men's-health clinics as an oral testosterone-support option that preserves fertility.

12.5–25 mg · Daily or every other day (oral)

Synthetic gonadotropin-releasing hormone (GnRH) that prompts the pituitary to release LH and FSH, stimulating the body's own testosterone and sperm production. A shorter-acting, more physiologic alternative to HCG that TRT clinics increasingly favor.

100–200 mcg · 2-3x per week or more

A glycoprotein hormone that mimics luteinizing hormone (LH), signaling the testes to produce testosterone and maintain their size and fertility. A staple of men's-health and TRT clinics, used alongside testosterone to preserve natural production.

250–1000 IU · 2-3x per week

Kisspeptin-10 is a naturally occurring neuropeptide that stimulates LH (luteinizing hormone) and FSH release from the pituitary — driving testosterone and estrogen production. It's the master regulator of reproductive axis, used for both fertility and libido optimization.

50–100 mcg · On-demand or 3–5x per week

Melanotan 1 (Afamelanotide) is a synthetic α-MSH (alpha-melanocyte stimulating hormone) analogue that stimulates melanogenesis — the production of melanin — providing significant photoprotection. Unlike Melanotan 2, MT-1 has minimal sexual side effects and does not cause spontaneous erections. It is FDA-approved under the trade name Scenesse for erythropoietic protoporphyria (EPP). Used off-label for skin tanning, photoprotection, and potentially skin cancer prevention.

500–1000 mcg · Once daily (loading) then 2–3x per week maintenance

Melanotan II is a synthetic melanocortin receptor agonist that causes skin tanning, appetite suppression, and enhanced sexual function. It's the predecessor to PT-141 (same molecule before the sexual side effect was isolated and developed into Bremelanotide). Used with caution due to mole/pigmentation effects.

250–500 mcg · Daily (loading) then as needed

Oxytocin is the naturally occurring 'bonding hormone' — released during sex, childbirth, and social bonding. Exogenous oxytocin via nasal spray is used to enhance emotional connection, intensify orgasm, reduce social anxiety, and improve sexual satisfaction.

20–40 IU · On-demand

PROSTAMAX is a peptide bioregulator from Khavinson's series specifically targeting prostatic epithelial cells. It is a tissue-specific tetrapeptide designed to normalize the functional activity of prostate cells, support healthy prostate tissue, and address benign prostatic hyperplasia (BPH). Long-term studies in Russia show reduced BPH symptoms and improved urinary flow.

100–500 mcg · Once daily

PT-141 (Bremelanotide) is an FDA-approved melanocortin receptor agonist for hypoactive sexual desire disorder in women — and widely used off-label by men for erectile dysfunction and libido enhancement. It works centrally on the brain rather than blood flow, making it unique among sexual dysfunction treatments.

Testagen is a tetrapeptide (Lys-Glu-Asp-Gly) bioregulator from Khavinson's series that targets testicular tissue — specifically Leydig cells responsible for testosterone production. By restoring gene expression in testicular cells, it can help normalize testosterone levels, improve sperm quality, and support male reproductive health without directly injecting exogenous hormones.
