Testalamin: The Male Longevity Peptide You’ve Never Heard Of

Testalamin is a testis-derived peptide bioregulator designed to support testicular function, hormone balance, and male reproductive health. Originally developed in Russia as part of the “Cytamin” peptide line, it’s now gaining popularity among life-extension researchers and biohackers interested in natural organ-specific rejuvenation.

What is Testalamin?

Testalamin belongs to the class of peptide bioregulators, short peptide–nucleoprotein complexes derived from the testes of young animals. Unlike synthetic hormone analogues or testosterone boosters, Testalamin works by normalizing the gene expression of testicular tissue, helping restore proper hormonal rhythms without overstimulation.

• Category: Peptide Bioregulator (Cytamin class)
• Primary Use: Male hormone optimization, fertility support, testicular rejuvenation
• Legal Status: Sold as a dietary supplement in some regions; available for research use

How Does It Work?

Testalamin acts directly on the testicular cells to regulate protein synthesis and restore gene expression patterns associated with healthy male reproductive function. It does not act like a hormone or secretagogue—instead, it supports the testis in functioning more youthfully and efficiently.

Potential Benefits

• May support testosterone regulation naturally
• Improves testicular tissue regeneration
• Supports sperm production and motility
• No suppression of the HPG axis like exogenous testosterone

Research & Clinical Notes

Testalamin was originally studied at the St. Petersburg Institute of Bioregulation and Gerontology. Clinical research showed positive results in men with decreased fertility, age-related hormone decline, and testicular dysfunction.

“Testalamin has been shown to increase functional activity of the testes in elderly patients without adverse effects on systemic hormone levels.”

Suggested Use (Educational)

⚠️ Disclaimer: This section is for research education only. Not medical advice.

• Typical Dose: 10–20 mg per day
• Cycle: 10-day course, repeated every 3–6 months
• Form: Capsules (oral) or lyophilized peptide (research only)

Most users report best results when taken on an empty stomach in the morning. Often combined with other bioregulators for systemic rejuvenation.

Stack Suggestions

To maximize the benefits of Testalamin, it’s often stacked with:

• Epithalamin (Epitalon): Pineal peptide for circadian rhythm and lifespan extension
• Vasopressin (Vasolamin): Vascular support peptide for circulation and blood pressure
• Zinc + L-Carnitine: Supports spermatogenesis and mitochondrial function
