my argument is that EOD pinning isn't really necessary, as the prop ester is 12% of sustanon, it's hardly significant enough to bother changing the dosing scheme over... I mean, i think it factors into how sustanon is supposed to work, WHY make a blend of steroids that has to be injected EOD when you can just inject test prop EOD? The point of sust as with other long-estered steroids is to decrease injection frequency... The way sustanon is supposed to work is first the prop releases, then the phenylprop, and the isocaproate and finally the decanoate in a kind of cascading fashion, of course the long esters are still constantly releasing but doing so very slowly and that's why there's higher ratios of them.
