I've used Whinny by itself, had good results, some joint pain. Other than that it was all good. Basically I don't want to be bodybuilder big. I'm more of an endurance athlete, Swimming, running, biking, boxing. Any thoughts about Primo by itself? If not what would work well for what I'm looking for. Anything better? Thanks for your time.

primo alone will beifit you add some var in and you will see nice gains.
what are your stats?

Well, if you don't want to be big, don't eat big. You won't gain like crazy if you are eating for your current weight.

Tren kicks ass for gaining strength. Test of all types is great for gaining muscle and strength. Deca is good for the joints, but I think of Primo, EQ, VAR and others as ways to round out a stack. I am not really sure how much I gain from Primo alone (while I KNOW I gain from test alone).

But Primo and Var have few sides and are really safe. If your goal is endurance, EQ would be something to consider as well.

Ya thanks. Really helpful. My stats are 6'1 185, 8 percent bf. Bench 305, Squat? Don't ever max out. But like a said I'd like to stay around this weight, because I want to fight in this class. Plus It seems like a good weight for running, anything more than 190 it starts to hurt my joints when I put in alot of miles. Thanks again
What are the advantages if any, of EQ over Primo. And Primo over Whinny?

combine it with testosterone propionate for maximum effect if you want durability add boldenone
