Hello Dylan: First i would like to thank you for the daily information, I have learned a great deal of info on various topics. My Question is im a masters cycling competitor, and the GW-501516 seemed like something i would like to try, I purchased 1 bottle of GW from sarmsx and right away i had a headache for 4+ hours, since i only used this twice it was concerning. I was thinking maybe it was a reaction to the other supplements i take on a daily basis, those are 100 mg of DHEA, 500mg of magnesium, 500 mcg of B-12, 30 mg of pregnenolone,and 5000 iu of vitamin D-3. Im a little bummed out because i have a race tomorrow and the GW could of helped me. What do you think? Thanks again Dylan!!
