4 AD is a weight-building supplement that has a 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, the 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 prohormone, which contributes to the increase in the rate of lean muscle mass increase, as well as to increase strength and endurance. 4-DHEA is a steroid 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 with sterane carbon. 4 androstene-3b-ol, 17-one works indirectly and directly through its derivatives.

4-AD in the presence of 3β-hydroxysteroid dehydrogenases (3b-HSD) and 17β-hydroxysteroid (17b-HSD) is transformed to androstenedione and androstenediol, and finally to testosterone. The compound does not aromatize to estrogens and, as compared to 5-DHEA, has a lower ability to activate estrogen receptors. The preparation is ideal for mass cycle, building dense and specific muscle mass. It promotes the production of testosterone, supports the renewal of muscle tissue and effectively increases strength and endurance.

4-AD 90 caps
I've just finished my second bottle of 4-AD. This is a great supplement to fight lethargy when on a SARMS cycle. For this 3 caps did the trick but 6 caps a day (3 in the morning, 3 in the evening) works better. I recommend this as an add-on to any SARM cycle.
