Proviron is one of the oldest anabolic oral steroids on the market. It is one of the most commonly prescribed steroids in modern medicine as it has a number of unique benefits. In the performance-enhancing world, Proviron shares qualities similar to Anavar, Winstrol, and Masteron, so is commonly used during the cutting phase of a steroid cycle. It is also a sexual enhancement drug for men and can function as a mild anti-estrogen while on cycle.



Proviron (25mg x50)

Proviron (Provigen), also known as Mesterolone is a popular and unique oral steroid like no other. It is commonly used during the cutting phase of a steroid cycle as it shares qualities with Masteron, Anavar, and Winstrol. It is an oral dihydrotestosterone (DHT) derivative that is not C 17-alpha alkylated which makes it not liver toxic. Chemically it has been altered to have a methyl group added to the carbon one position. This allows the compound to survive hepatic breakdown once ingested, but decreases its total bioavailability compared to other C17-aa oral steroids. Proviron has relatively low androgenic and anabolic ratings but has other attributes that can be quite beneficial for users. It has a strong binding affinity to Sex-Hormone-Binding-Globulin (SHBG), which in turn helps increase circulating free testosterone. This along with its strong binding affinity to androgen receptors allows the user to get more out of the other anabolic steroids used during a cycle. Provigen also works as a mild aromatase inhibitor as it binds to the aromatase enzyme, decreasing estrogenic side effects. It is also prescribed as a fertility medication, as it is quite androgenic yet does not suppress gonadotropins like most other steroids do. It actually enhances sperm production and quality, so it is a popular sexual enhancement drug as well as a mild performance-enhancing drug.
