The first job for any PED user is to (over time, not out of the gate) find out how much test they can tolerate without using an AI or a secondary anabolic that functions as an AI (primo, EQ). Then, and there’s debate on this, I’d say the next task is to try to obtain your short term goals using nothing but test (and an AI as needed). I think Kurt havens is right when he says that way too many guys are reaching for secondary compounds when they haven’t even ran 500 of test. Even less have run 750 or 1000 of test alone. Trust me, that is a lot of gear and if you can control your E2 and don’t have any other sides like hair loss etc, it’s the best way to go imo.
Now once that’s all established and / or if you run into a road block while running up the test dosage, NPP isn’t a terrible option. Nandrolone is fantastic if you can tolerate it. And the only way to know is to try. Biggest side effects are gyno from prolactin increase, sexual side effects, and mental issues. If none of those come around, it might be a good choice. There’s lots of literature about nandrolone and cardiac toxicity, different topic and area under the curve matters. That is, you’re prob not gonna run 600+ of NPP for half the year for years on end.
Another option could be masteron. It won’t crash your E2 like primo or EQ, and it does add a different look to your physique. People say it’s not anabolic and that’s kind of silly. You need to be eating enough and most of us use mast for cutting. But even in a cut I notice increased strength and neural drive when mast is added. Sides include hair loss (can happen with any drug) and lipid issues. Some guys get BPH symptoms. As someone stated above the best drug is the one you can tolerate. Hence why we should spend most of our journey maxing out test.
