Ouch!!! I have a good size knot on my left glute (ass cheek). Guess I'll have to wait this one out. How long till the knot goes away you think? When I pin I have a foam roller I use to massage it in. Well it seems to have made it worse this time lol. I switch my glutes everyday when I pin. Maybe its time to move to a new location? Im running tren-A and prop loaded into one syringe 75mg/50mg Tren/Prop. 25g 1.5" needle. Curious to when I pin in my quad. I should put about 1" of the needle into my quad right? That 1.5" seems to long to stick into my leg lol.
