i still for the life of me can't figure out how someone would take all the time to draw oil into a regular sized pin,backload it into a slin pin the take an hour to get the plunger to move.i've tried it with HG,UGL,every type of oil base,EO base...nothing would go thru that pin.even the ugl susp i had,micronized and all,would get about 1/4 of the way down before i had to change pins.why not just do IM and alot of rotations? dlets and glutes you can hit once a week,that's 4 days right there.my bi's i can hit4 different spots on each one at least once a week up to 4cc's each.all this sub-q talk,idk,don't make sense.if it's an intramuscular drug then why are we trying to pin it sub-q...to lesses the scar tissue?if it's not going directly into the muscle then all you're gonna have is an oil knot that leakes,esp if you're pinning ed/eod.to each his own i guess.good luck with that one...
