Prohormones were once steroids classified as supplements back before the banning of all prohormones in 2014. This high powered compounds were sold as supplements when they were really a methylated steroid. These were all compounds that were made up back in the 50s and 60s that were never brought to the market as steroids so they were never banned. Companies like Gaspari Nutrition and many others started producing these compounds as pro-hormones. Gaspari brought to the market a pro called Halodrol that was an amazing product that had this stuff flying off the shelves due to the effect it had on muscle growth. Many companies knocked off this product and before December 2014 you could find it anywhere.
Today’s prohormones are a different breed and are mostly made up of DHEA, they do work but you wont see the results you saw from products back before the 2014 ban. These products will need to be stacked in order to see really good results. If you are looking for size 4-andro is probably the best bulking compound on the market today. You will hold some water with this compound but nothing like the old superdrol. Stacking 4-andro with 1-andro will get you some pretty decent gains, some users report gains of 2 to 5 pounds in a 8 week cycle. Most people that are still in love with the old compounds are not amused with this number. But lets face it 2 to 5 pounds are pretty good numbers when you are talking muscle gains. Most pro bodybuilders struggle to put on 10lbs of muscle in a year with a ton of anabolics in their systems. So I will gladly take gains of 2 to 5 pounds.
