Well, if I've said it once, I've said it a million times: Cutting is done in the kitchen. You can get lean on Test and Deca if you are eating for it. That disclaimer having been made, S4 seems to have more thermogenic and strength properties than Osta. 50mg ed, split into 3 or four daily doses is best (only a 4 hour half-life), and probably plan for no more than 4 weeks, as the vision sides will probably eventually hit you in time. The 50mg dosage is on the lower side, but slows the onset of the vision sides, which dissipate within days of cessation.
