I’ve been running 1 mile runs and 5K’s
I'm going to start training for a marathon by doing some half marathons and I'm already training my heart by doing heart rate intervals long distance.
I’ve used GW501516 and it helped me a little bit, but nothing too much. Maybe i need to stack it with another sarm?
Can you give me a good stack. My current 5K time is under 20 minutes and i’m 27
