I have used sns daa caps, a cheaper daa cap, test powder, and currently taking d pol. Initially had some issues with sns daa caps so split the dosage to 2 morning and 2 pre work out and was fine. The cheaper daa caps i bought didnt seem to work as well but i found out this was because it may have been a different kind of daa. I took test powder and had awful gi issues thar i couldnt tolerate so i tried d pol because kf he great reviews i saw it get plus the experience i had with nitrates in no3 black chrome and have tried either pre workout or with my first meal. The first time i took pre workout i ripped ass a few times and it was deadly so i switched to the first meal and so far has been good no gi issues at. Considering test powder sells itself as a month supply under the pretense of taking it only six days a week i would just buy sns agmatine and daa or dpol and the sns agmatine
