I have had drawn blood after spent one bottle olympus uk gharine, was using 20 mg evey day. Now i am on second bottle and try bump to 30 mg every day but side effect was horrible (starting gyno because of bloating, suppose raise estrogen and prolactin). Hgh after one month jump little from 0,23 ng/mL to 0,35 ng/mL, and igf 1 from 19.2 nnmol/L to 34.1 nnmol/L. Every night before slleping i am taking 9 mg melatonin and 5 mg gaba. After few month i will do bloodwork to check values one more time. So mk 677 do it job, but they need some time to fully kick in.
