IMO, Test Enanthate and Sust have basically the same release schedule. So I don't think sust is really worth the added price. Some may disagree, but that's my experience with the two
I had a 4 star experience with Sust (fast acting, great gains, fat loss). By contrast, Enanth seemed to take forever to work, modest gains, not so much fat loss. But I appear to be in the minority.
