Hey guys, I've been blasting & cruising on sustanon for over 2 years now. I use the same trusted suplier, so I know it's not my gear, but lately when blasting I feel as if more is needed and my body has gotten use to the compound. Would it benefit me to switch from sustanon to cypionate? I'm not going to tell you my doses to spare me from those "test is test, you can get by w/less and, at that dose you're just wasting it" comments, but I will tell you what I'm taking. Mk-677 and sustanon -- blast & cruise and throw in masteron e and tren e for 8-12 weeks at a time when blasting. I would appreciate the feedback, guys. TY!
