NPP is a good start to nandrolone. Short ester so if you have sides you don’t like you can drop it and it’ll clear quicker. Sets on quicker, comes off quicker.
For size, 500/500 test/nand is very common. With NPP, you need to inject it at least every other day. Need a good AI and something for prolactin. P5P works for me and others, which you can try, BUT you want caber or prami on hand just Incase that doesn’t work for you. Cycle length you can go anywhere from 12-20 weeks really
