GP Stan 50 is an injectable steroid which contains 50 mg per ml of Stanozolol suspended in water. Some bodybuilders claim that the injectable version of this steroid yields better results than does the oral version. The water base of this substance means that it gets into the system very quickly, therefore requiring frequent injections to keep blood levels stable and consistent. Winny, as it is most popular referred to, is one of the most popular steroids in use today. GP Stan 50 has very low androgenic properties and very high anabolic properties. GP Stan 50 does not have the ability to aromatize and therefore will not cause any water bloat. This has made this steroid very popular with bodybuilders in the cutting phase of their training.
