Is it a transdermal ? If it is than I'd rather go with T-1 which has 10 grams of 4-AD, and 5 grams of 1-Test. I'm sure the T-1 is probably cheaper and it works great, check it out at the member store. If you want to save even more money, than just homebrew your own 12 grams of 4-AD. Check out Cur2Go's recipe. I hope that helped
