just curcumin and bioperrine, my maintenance dose is 1500 mg, 3000 mg a day when I'm actively trying to lower it. Why would I use anything else if I don't need to? I've always hydrated, is not and never has been the issue. Has kept me in the low 50's, and Im comfortable where I'm at. Highly recommend aerobic exercise to go with it, and for that matter along with any T therapy.
