Proviron-lab has the active substance Mesterolone and is one of the oldest steroids manufactured for medical use.
We cant consider it a steroid and actually in medical literature it was emphasized as a fertility aid. Some users say it is was effective for depression, anxiety and to boost lack of sex drive.
Those that compete will appreciate proviron’s hardening properties. Since proviron is 5-alpha reduced and not capable of forming estrogen, it will help give a drier look.
So basically this product can be used as a helper or ancillary compound in next cases: hardening look, or making other steroid you already take working better because Proviron has a strong binding affinity to SHBG which means more free testosterone circulating and more sex-drive 🙂
Some studies say it surpress LG (luteinizing hormone) which means it better not be used during PCT also if user is prone to baldness Proviron will increase it.
