Ok as of right now im natty but i plan to use gear sometime in the future,Anyway i was at the Dr's today and got a little taste of what pinning must feel like and to be honest not sure if i can handle it

I used to have fear of needles but not anymore.So i had bad strep past few weeks so the Dr decided to give me a shot of antibiotics into my quad intramuscular,and from my knowledge same way people that use pin and damm that shit hurt nothing like i expected.Afterwords i felt like shit a good 15mins and even 6 hours later i still have pain in my quad.

Does injecting gear hurt this bad???
