I agree but some noob injectors seem to balk at IM injections, seem too invasive which is why they tried these other methods of admin. Most here wouldn't even do 4ml IM in the glute. It's like 3ml in the glute, 2ml in the shoulder max. Though I've known bodybuilders who have done 10ml in the glute at one time, I did a combo shot of 6.5ml in the glute every 10 days or whatever at some time, no problem at all and I'm far from big.
I don't seem to have much scar tissue in my glutes, not that I can "feel." No Synthol- like hypertrophy either lol.
