4-AD is a mass building supplement that has powerful potency!

4-AD from Brawn Nutrition will help you feel stronger than ever before. The 4-AD supplement is an active hormone: 4-androstene-3b-ol, 17-one. In muscle tissue, enzymes convert 4-androstene-3b-ol, 17-one into the target hormone testosterone to obtain muscle mass.

It is an anabolic androgenic substance classified as prohormones, which contributes to the increase in the rate of lean muscle mass building, as well as to the increase in strength and endurance. 4-DHEA is a steroid compound structurally similar to 5-DHEA, from which it is distinguished by the location of the double bond not between 5 and 6 carbon, only 4 and 5 sterane carbon. 4 androstene-3b-ol, 17-one acts directly and indirectly through its derivatives. 4-AD in the presence of 3β-hydroxysteroid (3b-HSD) and 17β-hydroxysteroid (17b-HSD) dehydrogenases is converted to androstenedione and androstenediol, and finally to testosterone.

2-3 capsules a day for 4-6 weeks.
