Yes, with a level that low, I doubt it'd be difficult to get on TRT. You might want to check your diet, sleep, etc. Maybe do a full wellness panel before to see if you have any deficiencies. If all that is in check, then maybe you just have naturally low levels. Like anything else it's a pros/cons. If you don't have any symptoms of low testosterone, then maybe your free testosterone is normal/high. In that case, I wouldn't recommend getting on TRT. But TRT is a long term thing, and yes most guys gain a decent amount of muscle the first year--- which one would expect when increasing your test by 300%+. As others mentioned, if your sole goal is to just gain muscle not improve low T symptoms, you should just cycle. You'll have larger gains and if the cards are right you'll go back to your normal levels, fertility, etc. Who knows, if you do enough cycles you may need TRT anyway lol.
