So im 3 shots into my cycle (first one test cyp 500mg a week so 1.25cc twice a week) and im just curious about injection sites. first 2 where in my quads which were easy, used a 1.5" 22G which the length seemed really big. im a pretty small guy. today i did one in my shoulder (deltoid) and it was very awkward since i could only use 1 hand. i used a 5/8" 25G which some sites say is too short but i feel like that is plenty long for my shoulder (any input would be appreciated on this). my question is that i am thinking about doing it in my chest (pectoral) come monday and wasnt sure if that was as safe or not. r there a lot of veins or is it just as easy as the quad n deltoid? same question about calfs n traps coz those r possible injection spots i have been contemplating. for my shoulder, the shot i did today, am i going to know if the test didnt actually get into the muscle if i didnt go deep enough or will it just not work and me never find out? i have both 1/2" needles and 1" needles so i wasnt sure what would be appropriate for the muscles i am lookin to do.
