What causes injection pain?

[chris06749]

The BA content?
BB?
Or the Ester?

For example, alot of people suggest 2%BA and 20%BB for most conversions, now with prop this kills but with other hormones it's pain free? So i am right in saying it's the ester and not the ba/bb that cause the pain?

Thanks!

its the hormone most of the time. solvents rarely cause pain unless you are sensitive to a particular one. esters do not cause pain. in fact esters help to alleviate pain. thats why longer esters can go pain free at higher concentrations.

It comes from....
Shaking the needle, tearing muscle fibers
Swelling due to having a few cc's of oil where it doesnt (normally) belong
Hormone specific pain (prop, high dose anything, etc)
BA/BB? Maybe, but never in my experience has either hurt, even at 100% concentration

ya BA doesn't hurt for most.....I was shooting almost staright BA when I ran LR3-IGF 1 and it didn't hurt at all.
