with a 3-4 day halflife at some point the injection frequency becomes overkill. For me re-injecting when half of the half-life has expired is the most you need to go.
The reason I ask... I have 200mg NPP and it is leaving awful swelling and pain at the injection site. I am shooting 1cc (200mg) and 1 cc test cyp EOD and even cutting it with cyp is doing nothing. I thought maybe using 1/2 a cc (100mg) ED would have less of the NPP in each inject area and hurt less.
It hurts because it is 200mg/ml. Who is making NPP at that high of a concentration? Is it S**ra?? Most human grade stuff is between 25-50mgs/ml. BM is the only one I know that goes as high as 100.
