When people talk about injecting virgin muscle ,do they mean new to being injected as in being stuck with a needle or new to having the oil/water based product put into it. I ask this as i have injected delts many times with 25 g needles for igf but never put any steroid in to them. I have kick started my cycle with prop this time for the first 4 weeks along with sust eod and have had to use a ugl prop for the first time @1oomg/ml rather than the viromone @ 50mg/ml (2ml amp) i normally use.I have always done eod injections in glutes only with very little problems. This time my ass is very sore after 10 days (5 shots ) presume it is the ugl prop. I have another prop recieved today @50mg /ml and contemplating 3ml shot (1ml sust with 2 ml prop = 350mg shot) and put 1.5ml in each delt.Just wondering if i will be able to pick my arms up tomorrow or the igf needles may have softened the blow.Thoughts anyone.Thanks.
