Proviron 50 mg by Stealth Labs features Mesterolone, an oral androgen known for its ability to support testosterone function, enhance libido, and manage estrogenic side effects. This version contains a high-dose 50 mg per tablet and comes in a discreet, unlabeled pack of 100 tablets.
Mesterolone doesn't convert to estrogen and doesn't suppress natural testosterone, making it a versatile tool in both on-cycle and post-cycle strategies. It's especially useful for enhancing muscle hardness, improving mood, and increasing androgen levels during a steroid cycle or recovery phase.
A typical dosage ranges from 25 to 75 mg daily, depending on the cycle and goal. It can be run during a cycle to boost androgen levels or post-cycle to help with libido and natural test support. Because Mesterolone does not suppress the HPTA, it can be safely used longer than most steroids.
Many users stack Proviron with aromatizable compounds or run it alongside Clomid during PCT. Check out our androgen support section for more related options.
