Thymalin

Calf-thymus-derived polypeptide complex (distinct from both Thymulin and Thymosin Alpha-1) used in some countries for age-related immune decline.

CategoryImmune Support
Typical routeIntramuscular
Half-lifeNot well characterized (mixture of polypeptides)
Common dose range5-10 mg/day for 5-10 days per published protocols
Typical cycle lengthShort courses, a few times per year

BioHack Track models Thymalin at a half-life of 1 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.

Reconstitution

Reconstitute with provided diluent or saline immediately before injecting.

Storage

Refrigerate; use reconstituted solution promptly.

Cautions

Not FDA-approved; sourced from animal thymus tissue, so origin/purity verification matters.

Track Thymalin in BioHack Track. Half-life, dose range and route come pre-filled from this library — log a dose and the app counts your vial down, models what is in your system, and puts it on the same chart as your labs and body composition.
