4-Andro by LG Sciences delivers the most powerful legal prohormone and testosterone boosting supplement available to buy. 4-Androstenolone referred to as 4-Andro is a patented bodybuilding prohormone that brought back the lean muscle mass gains since the Designer Anabolic Steroid Control Act of 2014.

What makes 4-Andro better than any other prohormone is the Cyclosome Technology. The average orally ingested prohormone only converts 1.5-4% of the active compounds. Cyclosome Technology uses a double loading process that allows for an almost fully bioavailable anabolic compounds maximizing the prohormone effects.

What makes 4-Andro legal is the 4-androstenolone is a naturally occurring DHEA isomer. Though the compound looks very similar to DHEA the difference is in the double bond in the 4 position where it gets is 4-Andro name from. 4-androstenolone may be the most potent of the 4 series DHEA compounds.

The key to the increases in lean muscle mass gains with 4-Andro has to do with how 4-DHEA converts 3b-HSD and 17b-HSD into Androstenedione and Androstenediol to produce testosterone. 4-Androstenolone converts to 4-androstenediol instead of 5-androstenediol which offers a more potent anabolic effect. This difference allows for a higher conversion rate of testosterone over normal DHEA.

A key benefit to 4-Andro is that it makes a great bodybuilding stacker as it can be combined with different muscle building supplements.
