How Permeable is Muscle with IM Injects?

[onefm]

Now I know the muscle has blood flow through capillaries that take in medications faster than SubQ, but how permeable of a tissue is it? I was having issues with knots after getting some thicker oil based gear. I tried warming it up, and that didn't solve the problem. Yesterday I did my inject of testosterone enanthate, and decided to push the syringe extremally slow. About 20 seconds for .5 mil. Today, I have no major knot and just mild soreness. I never thought oil could seep through the muscle like that.

Huh?

you're on the right path (I think), inject oils slow, try not to let bozo nurses disrespect you by injecting rapidly. your experience with soreness should improve as your body adjusts to solvents and technique gets better, gl.
