If you decide to do this test only cycle and run it for a while, 12-16 weeks let's say, it will most likely blow you away. I love tbol but it's not the best for aesthetics, it might just be the absolute best steroid for me personally for strength, endurance and no crazy sides, but a 6 week cycle of tbol or EPI compared to the results you'd get with straight test, an AI on hand and a solid PCT, you won't even consider anything else. Go ahead and pin test for a while man, get bloods done and all, workout like no tomorrow, the results will surprise you.
Also, I also use 300mg test E per week for my test cycles, sometimes with primo but never really go above 300mg test a week and it gives me so much damn energy, strength, motivation and gains (both muscle building and fat burning) that I never saw a reason to go higher. Just added primo to a few of the cycles but it didn't make a huge difference, the test alone made the magic happen.
