Propionate is one of my fave's Bro. However, I use it to potenate my Sustenon injections, so I don't know if I'd have any advice on using it alone. Last year I used Prop with Winstrol and did EOD injections of it, I ended up looking like the elephant man. I'd never use Prop that way again, the EOD injection regimen causes me too many problems with injection site swelling bruising, and pain.
The short chain ester is the BEST for a quick kick of strength and size. I find it exponentially amplifies the potency of Sustenon.
Peace,
