I bought a bottle of 1,4 andro from BAC about 8 weeks ago or so. It comes with a little spoon in it and gives info on how much to take. I trippled that. I got pretty solid from it and I definitely liked it. I would definitely buy it again. I also bought the other dht product, damn I can't remember the name of it. I liked that too. As far as whether it's as effective in a powder as in a capsule, I have no doubt that it is. As far as stacking with 1-AD, yes! I had good results with 1-AD. I also tried Mag-10 and I also liked that. I think a nice stack would be the combination of Mag-10 (or 1-test but I like the addition of 4-AD to Mag-10), 1,4 andro and 1-AD. But I'd bump all of the dosages up to triple what's on the bottle, keep the cycle no longer than 6 weeks and also get some HCG for when you're done as well as Arimidex for during. Like 1/4mg eod. I know some of you don't like hearing that but you have to face the facts, this stuff will act on your body just like the real thing will. You WILL get shut down if you don't protect yourself. Anyway, I hope that helps. But I'm now waiting on Molecular Nutrition's new product which is coming out in the coming weeks. Supposed to be ass-kickin'!!!
