An FDA-approved product containing this compound exists, and its label is linked under Primary sources below. That label is the authority on dosing; the range on this page describes what people commonly track, including off-label use, and does not replace it.
Supplied pre-mixed in oil; no reconstitution needed, but warm/roll vial before drawing.

Primary sources for Testosterone Enanthate
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.
