So this is pretty much common knowledge at this point in mid 2025 that for whatever reason(doesn't matter actually) there is clearly a shortage of Masteron raws and for the last few months and maybe the whole year so far even if you ordered Masteron E or Masteron P your most likely not getting what you paid for. Pros even running UG lab gear that's normally dependable and high quality are getting half way through their prep and right when they run high Masteron to dry out and get dialed in instead of drying out they get the opposite effect and all of the sudden they are really full and not drying out AT ALL. Prep ruined, forcing them to back out of shows last minute(Sound Familiar?)(Nick Walker...Maybe?)And it's because the MASTERON shortage has all these labs faking the Masteron and come to find out it's just Test Prop or Test Cyp. Same reason you notice alot of reputable sources are out of stock on Masteron E. SO when you see some rando source that has an endless supply of Masteron, use some common sense and ask yourself how is this possible. For example you pin some 100-200mg/ml Masteron and come to find out after it's tested it was only dosed at 50mg/ml Test Prop. Basically the cheapest way to fake gear is with Test P raws. And that's exactly what's happening. And one can assume Primo is most likely being affected as well since Primo is often faked w/ Masteron(much cheaper). This is not info I've gathered here on Eroids but info that's being well shared around online from Pro's to Researchers to Gym Bros to TRT. But there are already testing reports users here are sharing showing exactly that, Masteron testing as low dosed Test P. So if you have bought any Masteron this year and your prep isn't quite right and it feels off or your lean bulk do us all a favor and send a CC off for testing and report back. My advice if you wanna steer clear of this and avoid the fake gear, whether you're cutting or bulking just run good old trusty EQ instead of fake Masteron/Fake Primo. Remember back in the 90's & 2000's all the pros were just running Test/EQ/HGH on prep. Yes they were prepping with EQ. EQ has very similar estrogen lowering/controlling effects same as Masteron does. There's literally no reports or testing showing EQ being faked. So maybe your next prep you run Test/EQ/Tren. That will be a solid prep no doubt. Maybe some Anavar if your into orals. By all means if you have testing reports on your fake Masteron share them here on this thread.
