They strenthen the tendons bud if used with correct training, i.e low reps, low sets, heavy weight. Also they build up fluid around the main tendons thus reducing pain, so 2 things to help!!

I know a 22yr old girl who has done her tendon in her shoulder. She is a stripper and has to go on the pole and all that stuff so needs to be able to move well. She is using Anavar at the mo' and its really helping. We did try Winstrol but it did not help due to it not having the fluid retention that a lot of other AAS have.
