No definitely not. Animal Pak does not have the correct aromataze inhibitors to prevent estrogenic side effects. Stick to AI's like A-dex & Aromasin on-cycle and standard PCT (Nolva, Clomid, HCG, "aromasin").
Just want to mention, that if your doses are relatively low and you are doing a simple test cycle, it is not essential to include an AI. Although it would be better to have one on-hand to be safe in case you encounter some estrogenic sides.
