ey bro not to be alarmed d i loved test prop 100mg i use to get from a bladder and omg thinking back omg did it hurt 4 weeks and still had a third shoulder on both left and right shoulders where i had injected ran outta spots to inject in and had massive lumps but just rub them every now and again because prop causes alot of scar tissue if u inject in the same site over and over and sometimes to ease the next injection you do of prop if you are still using, try how ever much you use and draw it back take the
needle off the top and place in microwave for 5-7 secs max and then reapply
needle and inject takes the pain away all together i recon
