APF Pro is the most advanced adaptogenic herbal formula for use in equine athletes. APF Pro combines the proven nutritional technology of the original APF (Advanced Protection Formula) with the muscle-building power of 20-hydroxyecdysone (20E). 20E is a safe and natural plant extract found in Rhaponticum carthamoides. 20E is one of the most widely researched nutrients used by top athletes and body builders for its remarkable ability to safely increase lean muscle mass during strength training. None of the adverse effects of anabolic steriods are found with 20E. APF Pro is unequalled in its protection of both the immune system and cellular metabolism. APF Pro gives your horse all the stress protection unique to our original formula, plus the added ulcer-fighting benefit of Aralia mandschurica. Veterinary researchers have found Aralia can have important protective benefits against stomach ulcers caused by stress. APF Pro combines APF – the only adaptogenic formula backed by university-level research- with advanced muscle-building and ulcer protection to deliver the most effective nutritional formula to support your horse’s health and performance. *Price valid for online purchases ONLY!
