i have found the gains from tbol to be less dramatic than dbol, but as for toxicity, in my personal experince, i found OT to be one of the worst orals i've used. it dramatically threw my cholesterol out of wack, more so than dbol ever had and it appeared to be no less liver toxic than dbol or other orals i've used. personally, it might be one of my least favorite orals. thats just an opinion. if you're looking for something that works well and is on a little more of the mild side, for side effects, anavar would be my suggestion. strength gains are good and if you're eating enoug food, while lifting hard, you can make some gains while not putting your health at quite as much risk. 50mg ED is a solid dose for 6-8 wks total, followed by PCT

as for "bridging", i dont believe in it. if you're taking a steroid, you are not "off". at best, you are not going to recover as fully on a bridge vs taking time off. if maintaining gains is your goal of bridging, you are only going to prolong the inevitable. eventually, you will need to come off, and at that point, it is going to be even harder to recover, having stayed on for so long. be smart. take your time off and recover your natural test. in the long run, you will be glad you did
