I don't understand where the idea or "bloodwork" is coming from that you could run just about any real AAS without shutdown? I'm relatively new in this space is there anything that a man can run & still get returns plus not simultaneously shut down their natural production?
Not real gear no... You can run bullshit test boosters... Amazon shit... But no. Any real gear is going to shut down your natural levels. That's why all men run test as a base... Then add compounds like deca, tren, mast, primo, anavar, dbol, Halo, anadrol, npp... You can't run any of those things without running test.
The only thing I know of that you can run that will help is HCG.
But... I don't have much experience with that compound by itself.
Everyone I know that runs hcg is also on test.
