Anecdotally, no objective nor subjective benefits for me. I followed the leading loading-phase protocols to a t, and cycled off after 12 weeks. Cycled back on after 10 weeks. After a year and a half, I can honestly say it provided little to no personal benefit. My training consists of 12-18hrs a week of structured riding, + gym routines in the off-season. Creatine, protein, proper sleep hygiene- now we're talking gains.
