Do you have a history of depression at all? NPP is amazing for keeping you looking full, but the couple times I’ve used it, I’ve noticed a pretty big increase in depressive feelings. Nothing else has done that, tren makes me happier and trest doesn’t have much of an effect on my mood, but both are 19-Nors. I don’t know why that’s the case with NPP, but I have definitely noticed a correlation. Could be completely coincidental, but it’s happened both times I’ve ran NPP. Just some food for thought if you run it and start feeling more down than usual and have no idea why… it could be the nandrolone. Other than that, stacking NPP with tren is god-mode. I regularly eat 800-900g of carbs when using both of them for bulking and my body fat levels stay low. I really have no idea why people say not to run two 19-nors together, but in my experience… it’s bro science bullshit and no more harmful than stacking two other similar hormones together.
