Im in rugby season again and the training is insane. Tons of plyometrics running and core strength plus weights. So i decided to buy a helping hand. Im taking cissus to prevent injury and hopefully combat the prostan's effects on the joints. A question I have was has Prostan ever affected people who do cardio. We run a mile every other day and probobly around 5 miles 3 days a week. I also wanted to take this to hold onto some muscle. Thanks and I'll try to keep updated on how its workin.
