i've been injecting 4 vials of sten a week for the last 5 weeks(2cc's a vial)alternating between quads. i want to try injecting into my bi's but 2cc's seems like alot. should i inject 1cc into each bicep on the same day? i also want to inject into the delt but i have rotator cuff problems. will injecting into the delt make it worse?
