Yes, they definetly did yield good results ... but all my friends are on steroids / anabolic steroids ... I didn't want to get into that so I tried a safe alternative ... I think I'm just going to stick with BSN products (NO Xlplode, Cell Mass, etc.) Yeah being only 18 can probably screw around with hormones so I may wait till I'm 21 to start experimenting again ... Although on the bottle of BAM or JW ( I cant remember which) one said take if your 18 or older (which I qualify for) while the other said take if your 21 or older (which obviously I don't qualify for) so yeah. I am now taking Hawthorn Berries (565 mg) and Milk Thistle (1000 mg) for liver support just in case it did any liver support.
