Dont know what to use because from what i´ve been reading on alot of boards i´d say about 70% of poeople say lr3 doesent work and 30% say it works ,i´ve tried lr3 twice first time a premixed and i got nothing from it and next time generic and it was better but i didnt get crazy pumps i got really hungry after injecting it and muscles were little fuller but now i cant deside if im gonna run hgh or lr3 but a higher dose ,last time i was on 60mcg,maybe 80mcg-100mcg would be better.
