ok first off, Enanthate is not active as long as Sust. You can easily tell how many mgs you have in you're body, but with Sust you really can't, thus the guessing games.
I used Omna/Winny/T3 a few months ago, for a bulking cycle. It kicked ass, you should definitely think about using 25mcg for protein synthesis.
But all in all, i think the Primoteston is a better product.
