My 2ml deca only gives me 1.7ml in reality, so i am looking at spliting a 2ml vial with my partner thus giving us both 2.5 ml give or take a ml. We inject twice a week mon and wed, which would give us 5 ml a week, is this alright as i have read a few posts where it is said not to shoot more that 2 ml in any single injection. This is our first cycle, and we are a week into the cycle.
