I initially bought a starter and now have picked up the limitless kit(53 year old male @ 200lbs and 6'2"). I used Amp this past month for cycling 40 plus km’s cycles, and for fairly long hikes/trail runs(usually between 800-1600 meters of elevation between 6-28 km’s). During the month-plus of use I have had 6 days off from doing any activities. I noticed Amp’s effects on recovery, endurance, and also while attempting to match and exceed segment times. I noticed the day following that my recovery was noticeably better than days I chose not to use Amp. I recall a few times where I improved my average cycling speed while doing the same road circuit(I have increased my average km/h by 1.1km over 5 weeks; now at 28.6 km/h avg) on a 42km and 360 meter elevation road circuit. I also used nutritional supplements(my usual ones) along with training techniques to compliment Amp during this time period. I started with conservative amounts but recommend the ‘more is better’ approach with Amp. I now use liberal amounts before and some after exercising.
