These are big boy steroids, specifically the Tren, Aka trenbolone.
Tren is not a first cycle steroid, Tren is the steroid equivalent of doing a deal with the devil. It is HEAVY DUTY and has dangerous side effects, but it is incredibly effective. When you see bodybuilders that look like the Incredible Hulk or something out of a comic book, there is a good chance they are on Tren.
Stanazolol, Aka Winstrol is a very commonly used steroid which is great for maximizing strength and power even when trying to cut weight, it is used in medical situations for “muscle wasting” - preventing people from losing all their muscle due to disease.
(Also great for building mass, but athletes in combat sports who need to make weight tend to like it because it gives a lot of power without needing to add a lot of weight)
Drostanalone - Aka masteron, is another common steroid, considered one of the safer steroids, but in this case it is just a supporting actor.
This is a big boy cycle. Definitely not his first, and honestly wouldn’t be advisable as a second or really a third cycle either, it could be... but generally people don’t fuck with Tren unless they have maxed out where they can get with the wide variety of safer steroids.
I’m surprised he didn’t pop for testosterone, as I would think the Tren would crush his natural production (even if it didn’t, the others would) so he probably got lucky there or they figured that they had him on enough other stuff that they didn’t bother to mention the testosterone ....or maybe they just ran out of characters in the tweet.
