that would be mk677 but i would also go with the other two compounds you asked about with mk2866 and gw501516... however your dosing on 677 is so far beyond absurd... 25 mg is the absolute max... go ahead and do something ridiculous like 100 mg of mk677 and see how that works for you after a few weeks... you'll be done using it period... stop being absurd and do things the right way...
1-12 GW-501516 (CARDARINE) 20 mg day dosed once a day in the a.m. 1-12 Mk677 (NUTROBAL) 25 mg day dosed once a day in the p.m. 1-12 Mk2866 (OSTABOLIC) 25 mg per day first two weeks then bump to 50 mg per day, dosed once a day in the a.m. 9-12 N2generate https://www.needtobuildmuscle.com/store/hcgenerate-n2generate.html
