I got serious doubts about that LGD-4033 and especially for the prices that are listed for that stuff. I ran an entire bottle of that stuff at the recommended dosages and when that didn't work I uppped the dosages to almost double the recommended....results were nothing. For the amount of money I spent ont that stuff when it came out I could have bout 3 bottles of Test E 250 and had guaranteed results.

The only SARM I've ever run with positive results was MK-2866 (Ostarine) and even recommended it to my friends that don't run gear at all. A few tried and they really liked it.
