I've taken it plenty of times, you can get good results using it solo, and it will actually increase your libido and never gave me serious sides, so it is pretty pleasant to be on. You are not gonna be a bodybuilding monster if you use it, but if cycled responsibly you can gets some good lean gains, the drug seems way more anabolic than anavar and winstrol to me. There were a couple of strong German monsters that actually used low dosage tbol solo with a 4 week on 2 week off protocol for years. A couple of them got ungodly strong, I'm sure the drug helped some, but they also trained like no tomorrow....
