Shorter-acting injectable testosterone ester requiring more frequent dosing than cypionate/enanthate, sometimes preferred for more stable blood levels.

Typical routeIntramuscular
Half-life~0.8 days (~19 hours)
Common dose range25-50 mg every other day (TRT range)
Typical cycle lengthOngoing under medical supervision (TRT) or defined cycles

BioHack Track models Testosterone Propionate at a half-life of 19 hours, so every dose you log is decayed against that curve and the app shows estimated active levels — not just what you typed.

No approved product cited

No FDA-approved product for this compound is cited on this page, and no approved human dose is quoted. Treat the range below as research and community practice rather than a prescribed dose.

Reconstitution

Supplied pre-mixed in oil; no reconstitution needed, but warm/roll vial before drawing.

Storage

Store at room temperature, away from light.

Cautions

More frequent injections than longer esters; same prescription/monitoring requirements as other testosterone esters.

Track Testosterone Propionate 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.

What the evidence says

Evidence Check asks 10 questions about every compound. For Testosterone Propionate it can answer 1 of them, from the papers we hold — graded by how strong the study design is, not by whether the findings are flattering. These are the same verdicts the app gives.

Work it out

Selected published studies

6 papers naming Testosterone Propionate in the title, drawn from PubMed and limited to reviews, meta-analyses and trials. Each was checked against PubMed’s own record for its title, journal and year. This is a starting point, not an evidence review — nothing here is offered as support for the dose range above, and the list is not exhaustive. See the editorial policy.

Where these figures come from

The half-life, route and dose range on this page are compiled from published pharmacokinetic literature, manufacturer and product monographs where one exists, and the ranges commonly reported in clinical and research use. They are kept as a range rather than a single figure because that is what the sources actually support — a half-life varies with route, formulation and the person.

These are not citations, and this page is not a review of the evidence. Where a number matters to you, follow the database links above and read the source. We say so plainly rather than dressing a compiled reference up as one.

Nothing on this page has been reviewed by a named clinician. It is a reference for people already tracking a protocol, not a recommendation to start one.
