I'm on 10mg of sarms1 LGD with no issues but I've been on 10mg+ taurine every day too. Mr supps carries bulk taurine and ships out pretty fast if you're in need of some
I only had like 2 incidents with back pumps but after that I had no problems. Potassium and lots of water will take care of it if you don't have taurine on had.
My first 8 week cycle of LGD consisted of no taurine use and I never got any shin pumps nor back pumps..and my dosing was consistent at 6-8mg for weeks.
