Like needto said test suspension is by far the best for putting on substantial amounts of size quick but it does come with alot of water tension.I actually prefer Enanthate or test sus. I seem to hold more water on cyp.
Sustanon no doubt. I use it in every cycle wether its bulk/cutting. When Im cutting I still keep taking 1 shot of sust and the rest from Prop due to the bloat.
But when I went up to 1g of Tren and 1g of Sust for 10 weeks that was crazy
