There are many threads on here of people just taking T1Pro. As a matter of fact, Chemo has a link below his signature to one. Plus there are plenty of others on this board that have posted info. about T1Pro cycles by themselves. You may want to try and look a little harder. Remember to keep your diet in check, cals. up, training volume a little higher, and make sure you have something for post cycle. Some also complain of lethargy and loss of libido, you may want some 4ad handy for this. There are some other things you can do, just look through some of the threads here, you can find all this info. But if all is in check, you will see good gains. I would also recomend using that T1Pro as two four week cycles. Some have done this and are getting good results with a moderate dose for 8 weeks total. 4 weeks on, 4 off, 4 on, then at least 8 off, that is if you want to do another cycle. I had great success off One+ for 3 1/2 weeks and I am looking forward to using one of Chemo's products next. I hope this helps ya!!
