I did a couple tbol only cycles a few years ago (mid- to late-30s at the time) and had no issues coming off. Tbol is a pretty mild oral as far as that goes, but everyone is different and there is always the possibility you may see some sides that I (or someone else) did not.
That being said, I gained a few lbs each time (around 10 I believe) and saw an increase in strength. I had to keep my dose at 40mg/day, because even at that low of a dose I would get back pumps in 4-5 weeks. After coming off, I had no issues with libido or anything that I noticed, lost some of the strength I gained each time, but both times it leveled out above where I was pre-cycle, same thing with weight. Tbol is my go-to oral, I’m planning on getting some more here soon. Nice little boost.
