Ive done test e, c, and prop at various times in stacks and as stand-alones
I stay lean as a cock (sub 8%) all year round while using and while clean so I definitely see changes
at 500 mg/week I haven't seen much difference between enanthate and cypionate - increased strength and size, constant libido, sustained rock solid erections, increased aggression (not a bad thing in my perspective especially combined with high libido)
unfortunately I get a bloofy moon-face and water retention around my mid section, lots of sweating, plus bacne (not terrible but enough to occupy my wife)
on test prop 1.5 cc eod (I forget the exact mg per ml) I was gtg in less than 4 days - hard, dry, full
on prop I didn't hold any water and I could trace my ab veins up to my ribs - ridiculous
the only disadvantage to prop, I found, was that the injection site hurt like a son of a bitch for days after, making squats difficult after pinning my quads. I still sweat a lot too
for me the perfect cycle would be 100 mg test prop + 100 mg tren ace eod or ed - guaranteed muscle god in days (provided you're LEAN!!!!!! - these miracle drugs are wasted on fat people)
as an aside, I love tren ace but it gives me serious ED requiring daily cialis and/or test stack - ironic that it makes me look like a sex god, yet leaves me struggling to maintain an erection - not worth it . . .
