I find that people do recovery from NPP much faster than Deca. I’m no sure what TPP is. Have never seen that one. Test Prop? If so, you could easily do 1cc along with 1cc NPP every other day. Or you could use long acting test, 1/2cc along with 1cc NPP. That would work just as well. You would just need more Ai than you’d use with the lower dose of prop which also wont build as high. If you can work glutes into your shot rotation, you’ll do your delts and quads a favor. The more often you inject into a muscle, the more likely you are to get scar tissue. So keep that rotation going and try to rest sites for as long as you can. After 10 wks a guy can feel pretty beat up with EOD shots.
