Some people do and some don't. That is probably the worst side effect on Superdrol, with the exception of not taking proper liver care. Superdrol is very powerful and will get you BIG!! I would not worry about Beastdrol, just drink plenty of water and food with it and yes, there is not much you can do about it but stretch and relax them muscles. You could take some glutamine for back. Correct me if I am wrong anyone cause its either that one or Taurine.
