I do fine with 500 test/350 nandrolone ratio
Like Big Paul said 2x is a good rule of thumb also. I would bet you get the same affects with your 300/250 ratio
I run nandrolone all the time at some dose blast or cruise. Have run both Deca and NPP many times. Now I run both. I keep 105 Deca for my cruise and add NPP for my blasts (usually 250)and combine the total for 355. That way I can drop the NPP at the end of the blast and I don’t have to worry about the long ester Deca in my cruise, other than the 105 Deca I always run.
Some people claim less sides with NPP, I haven’t noticed this at all. It’s both Nandrolone just different esters. A lot of people say less water weight with NPP, maybe that’s the case but imo it’s negligible. I think the sides just hit different when they last for weeks instead of a couple days lol and that’s why people say less sides with NPP
As far as your sides go if you had a problem with Deca you’re going to have the same problems with NPP until you get your Test/Nandrolone ratio correct for you. NPP will clear much faster if you get it wrong again.
Add 200mg P5P for the prolactin control
100mg in the morning 100mg at night
Controlling your E2 will also help
