Hi there! I am a former powerlifter and tennis player with nearly twenty years experience in weight training, body composition, and men's and women's health & nutrition. I am not a medical doctor but my knowledge of nutrition, kinesiology and a wide range of supplements is likely more extensive than your local health practitioner. Using my iHerb code MAV445 at checkout will save you $10 off your first iHerb purchase of $40 or more, and $5 off on smaller orders. I have used iHerb for many years now and find that it always provides excellent value for money and an outstanding range of products. Cheers!
