I think I must be misunderstanding. Test and tren will at some point stop your natural test production. That to my knowledge is unavoidable.

The bit l must be misunderstanding is which natural test production (assuming the test and tren will stop it) will the proviron keep going.

I'm not having a dig, honestly. If you've got a way of keeping my natural test flowing while I take test and tren then I'm very interested. It's just that nothing I've ever read suggests that it's possible.

I'm aware that adding proviron means more free test available and therefore adds to tests effects.
