i jabbed 3.3ml ed for a while
i had always used high concentration gear before and it always left me crippled ... test at 350mg, npp at 200mg, tren ace at 133... pip was HARSH
then i diluted all my stuff, actually shooting high volumes was ZERO problem from that point on... test e at 250mg, npp at 133mg or so and tren ace at 90mg/ml. i could shoot a mix of these three with 3,3ml a day and pip was pretty much nonexistant, except if i jabbed my lats and worked them later that day, then there was a slight discomfort
when i blast again my go to sites are delts, quads, glutes, ventroglutes, and lats (in my preferred order)
i often miss my ventros though, but if i hit them correctly theyre always completely pip free. can completely cripple you if you miss though lol
