I was just curious how much of a difference is it to take 400mg instead of 500mg. I was really hoping to find some test e. 250 but all i can find is test. cyp 200. I'll be getting 2 10 ml bottles and i'll be takin 2 cc's a week for 10 wks. I'd like to buy another bottle so i could do 2 and a half cc's a week to get 500 mgs a week but im payin way more than i should for this stuff so i don't have the funds. I'm still debating whether to pay the prices the guys asking for.
