I've just finished an 8 week stack involving some tren ace within a rip blend.
My thoughts:
Good - Strength, lean gains, no acne, no aromatisation, hardness, libido.
Bad - Lethargy, loss of appetite, piss like rust, slight paranoia, night sweats.
Like someone else in the thread said, it's a love/hate thing, gotta take the good with the bad.
