A three-amino-acid peptide made in Russia to slow age-related decline. Laboratory work — most from the institute that profits from selling it — shows the molecule entering cells, binding genetic material, and reducing damage in stressed nerve cells. Human evidence is thin: small studies without placebo groups, one finding pointing the other way, and no regulator has approved it. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Complete blood count with differential | Haemoglobin 13.5–15.0 g/dL (men), 12.5–14.5 g/dL (women); white cells 4.5–7.5 ×10⁹/L; platelets 200–350 ×10⁹/L | Detects the suppression of blood cell production reported in the one human study that looked |
| Homocysteine | 5–7 µmol/L | Identifies the metabolic state in which the strongest animal benefit was shown |
| High-sensitivity C-reactive protein | Below 0.5 mg/L | Tracks low-grade inflammation as a general marker of physiological stress load |
| Urinary 8-hydroxy-2'-deoxyguanosine | Lowest quartile for the assay's reference population | Directly tests the antioxidant claim against the conflicting pro-oxidant finding |
| Comprehensive metabolic panel including estimated filtration rate | Filtration rate above 90 mL/min/1.73 m²; alanine aminotransferase below 25 U/L (men) and below 20 U/L (women) | Establishes clearance capacity for peptide fragments and any contaminants before exposure |
| Urinary 6-sulfatoxymelatonin, overnight | Age-appropriate nocturnal rise present, with a clear day-night difference | Tests whether any pineal effect is occurring, and detects melatonin adulteration of the product |
| Morning cortisol and DHEA-S | Cortisol 10–15 µg/dL at 8 a.m.; DHEA-S in the upper third of the age-adjusted range | Quantifies the stress-adaptation axis targeted by the occupational studies |
| Fasting glucose and fasting insulin | Glucose 75–85 mg/dL; insulin below 5 µIU/mL | Provides a general metabolic baseline against which any unexpected change can be judged |
Cadence: Full baseline panel before the first dose, ideally within two weeks of starting; complete blood count and the oxidative damage marker repeated four weeks after the end of each course; full panel at six months, then every 6 to 12 months where courses are repeated.
