It’s unlike any 19nor. Think of it like a supertest that is a 19nor. Many of us have ran it Without test and felt great. Like more energy than I ever have had, great. Plus it’s something like 2.7x as anabolic as Deca which makes it over 3x as anabolic as test. And it will show. Libido and energy are on another level. Muscle building is amazing. Honestly besides the gyno, it’s almost the perfect steroid. I’ve said that a dozen times since 2015. Labs are always great, you can cruise on it, the side effects are close to non existent, anxiety is minimal, it’s going to EASILY put on more muscle at 300 a week than 500 test/500 Deca. Guaranteed. Technically it should be close to similar at that doses but I’d say it’s still better. 300 is usually too much for me, and I drop down to 225-275.
