Great Product, Excellent Mass builder. Need to include a test booseter (Trib) and liver support. Joint dryness, not pain was solved with Animal Flex. Will not show gains without increased protein intake and balanced diet plus hitting the weights hard. Dry mouth and increased sweating was annoying but not too terrible overall, just drink water and wear an undershirt! No acne, gyno and only mild mild agression, usually in weight room!
