British Dragon Mesterolone delivers 25 mg of high-purity Mesterolone per tablet—an oral androgen widely known as Proviron. Though originally developed as a treatment for male hypogonadism and infertility, it has gained significant traction in bodybuilding for its ability to enhance muscle density, boost libido, and support post-cycle hormone balance.
Mesterolone is a dihydrotestosterone (DHT) derivative that binds strongly to androgen receptors without converting to estrogen. It is not anabolic in the traditional muscle-building sense, but offers key benefits including increased free testosterone, sexual performance enhancement, and a harder, drier physique when dieting.
According to clinical research published by NCBI, Mesterolone has been effectively used for androgen replacement and male fertility, particularly due to its low hepatotoxicity and potent androgenic signaling.
British Dragon's 50-tablet count makes this ideal for 4–8 week durations. It pairs well with suppressive compounds or mild anabolic stacks like Stanabol 50 or Oxanabol.
Because of its mild nature and short active life, Mesterolone is often taken 1–2 times daily:
Most users cycle it for 6–8 weeks during cutting or as a bridging compound between AAS cycles. It is also a common addition to post-cycle therapy to help maintain mood, sexual function, and a lean appearance.
Mesterolone amplifies the effects of testosterone and enhances the free-testosterone ratio by binding to SHBG (sex hormone-binding globulin). It stacks synergistically with:
It can also be used during PCT alongside Clomiphene to offset libido crashes or estrogenic rebound effects.
While well-tolerated in moderate doses, potential side effects include:
Since it doesn't suppress LH or FSH, Mesterolone does not typically shut down natural testosterone when used alone.

Mesterolone increases free testosterone by lowering SHBG but does not raise total testosterone levels directly.
