I have been on test p 50mg/tren a 50mg for 4 weeks so I have been rotating sites, quads, hips, glutes, and delts,
My question is everytime I inject in delts (25g 1"), i get severe PIP so that I can't even raise my arms. I thought PIP would be less as I inject a few times. Any ideas or suggestions?

Also if I decided not to inject delts, quads, hips, and glutes would be enough daily injections, so I will pinning the same site every 7 days.
