I like a-bombs never feel bad when I take them. Yes they do bloat you up a little, espec if the diet is a little loose. 50 mg sould be good for the first time, of course 100mg would be better, but go easy at first, make sure you are using some a-dex or letro also cause the stuff can be sidey espec with test and deca. Ive used Syntex and nutri-vet both were good, of course the syntex is the best.
