The Brits use raloxifene, which is a SERM. I use Nolvadex with it and it helps. The idea is that estrogen effects at joint tissue is distrupted in stanozolol use. Normal estrogen is not strong enough to push the signal through. Raloxiphen is a good osteoporosis drug by stimulating bone and joint tissue activity. The idea is that it will do the same thing in stanozolol use.
