The only steroid I know of that has been said to give gains even while restricting calories is primo. However, that statement was made WAY before superdrol came out. On top of that superdrol is in a category that will most likely garuantee that it never gets researched like primo, test, anavar, deca and other AAS that where intended and still are intended for human use.
In other words there's no money to back the studies because the greedy cocksucker insurance companies who are hand in hand with the pharmaceutical companies have no interest in that sort of thing. Which I honestly can't blame them for entirely, they've got more important jobs to do...poorly.
Still bro, your staking slin and a VERY strong AAS. Here's a question? What's the most you've ever weighed? Becasue if you've been over 203 say 210-215 and lean then you're just experiancing some muscle memory, assisted by the compounds you're taking. Get me?
