I'm 2 weeks into my summer cutting cycle and one of the compounds I am using is Masteron Prop. My source was back-ordered on Masteron when I placed the order (I didn't know this at the time) and I had a few vials left over from a cycle from last year and I didn't want to post-pone my cycle. Anyways, I ordered Stealth Gear Masteron Prop and on the imprint there is a number 10 for the last 2 digits. Looking at their website this is Primo not Masteron. I know they are very similar with Primo basically just being a longer ester and way more expensive.


I'm waiting for a reply back from my source to see if they are going to send my Masteron out. I have at least 5 weeks left of the Masteron that I have and I can easily get more from the brand I'm current using but wanted input on those that have run Primo. If I were to switch to running Primo it will take a few weeks to kick in because of the long ester. If I go this route should I taper the Masteron off over the next several weeks? Or, should I just get more Masteron and save the Primo for next year?
