BioHack Track models Clenbuterol at a half-life of 37 hours, so every dose you log is decayed against that curve and the app shows estimated active levels — not just what you typed.
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.
Oral tablet; no reconstitution needed.
Store at room temperature.
Not FDA-approved for human use in the US (only for horses). Serious cardiovascular risks including tachycardia, arrhythmias, and hypertension. WADA-prohibited. Long half-life means side effects persist for days after stopping.
Track Clenbuterol 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.
Evidence Check asks 10 questions about every compound. For Clenbuterol it can answer 2 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.

Research references only. Not medical advice, and not a recommendation to take anything.
These open a search of each database for Clenbuterol — they are not citations, and nothing here is evidence for any particular dose. The same links are in the app.
11 papers naming Clenbuterol 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.
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.
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.
