... heres a "scientific" quote i found posted by HOSS
"Listen...site injections do not work!!! unless you have so much scar tissue in your glutes, quads, and delts that the pin will not penetrate, stick with those sites. The oil or water based compound simply seeps slowly into the bloodstream, no matter where you inject. That is where it works...not at the muscle directly...the blood then uses the extra test or whatever to increase protein synthesis, and increase red blood cell count.
The muscle itself just see's the oil as an obstruction and swells...but only temporaraly. If site injections worked I should have an ass so big I wouldn't need to sit...my ass would be touching the floor while I'm standing. And I shouldn't be able to wear ANY size pants without shredding the pant legs."
hrm ..
i'll just have to experiement more ..
