People swear by the winny/deca stack and it seemed to work for me personally.
Having said that, I've read that true winstrol "joint pain" is in the connective tissues -- ligaments and tendons and such since it dehydrates them. Deca creates a layer of water in the joint itself, which really isn't tendon/ligament related.
That's a long-winded way of saying "yes, it worked for me but others say otherwise"
