Thanks for the recommendations. So I found MK677 on domestic-supply. It is by Spectre Labs and it is 15 mg 90 tabs. Is this the correct one? If so, I'll get it. I was hoping to stick with a 12.5 mg capsule. I could not find 12.5 mg capsules/tabs on domestic-supply. Also, when I google "research chemicals mk677", the first result is Biosynth.com. Is this the correct site?
