Writting for my friend whos not by the comp now. He is using syds group Dec300mg and has horrrible pain in his a$$. He asked around to a few other people who are using the same product and they all are experiencing the same thing. Hes positive he did not hit a nerve or vein because each CC is 300 mg he knows there has to be a high Alcohol content. Currently right now he is doin half CC 2x wk. Do you think if he break his injections into 4wks with smaller dosages will there be less pain???
