BioHack Track models Testagen at a half-life of 0.5 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.
Reconstitute with bacteriostatic water; some formulations are oral capsules.
Refrigerate after reconstitution.
Not approved for human use in the US; nearly all data comes from Russian-language preclinical literature.
Track Testagen 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.
These open a search of each database for Testagen — they are not citations, and nothing here is evidence for any particular dose. The same links are in the app.
General reference compiled for use inside the app, not medical advice and not a recommendation to take anything. Dose ranges are what is commonly discussed, not a prescription. Talk to a qualified healthcare professional.
