Works great for anyone, not just for professional and athletic enthusiasts!! Had 6 major surgeries in past 8 years (arms, hands, and back). Sometimes simple everyday tasks can cause me to pay dearly the next day. Sometimes the pain is so geat that OTC & Rx pain relievers can't touch. If I I know I've overdone it that day, I'll take 4 caps at bed & 4 caps when I get up in the morning,.... I FEEL LIKE A NEW PERSON!! I'm beyond impressed how well this product helps me! I'm on my 3rd bottle and pray I'll always have access to this phenomenal product! I am a huge skeptic of supplements, fearing I'm not going to get the results I hoped for then have wasted my money. This product has truly changed my opinion. Even my Pharmacist said he's never seen a product this good for tissue recovery. Thank you Hammer Nutrition!
