hi guys, first of all i have to say that erase is great stuff, strength gains on it are amazing and it's helping me to stay lean while bulking. However i'm a little worried about a possible rebound of estrogens when the cycle will come off. There is a way to avoid it? Tapering down?Finally i have an other question. I'm running erase at 2 caps/day and have no problems, except when i do cardio (i do a lot of cardio, run about 10 miles 4 x week) which is the only moment that i feel joint pain, specially in my knees. There is any suggestion to avoid that?
