I am presribed ANDRODERM 4mg patched for day. I am not necessarily trying to get huge, but heard that thses patched are good to help with weight loss/maintenance.

After using a patch, there is still a lot of "product" in the patch? Is there any usable testosterone still in there? or is it the chemical that helps woth absorption? If it is still potentially usable, what would be the best way to apply it? Cut it open and apply to shoulders like ANDROGEL?
