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.

Very much worth it and works like magic, my first ride was 100km chairty at 30.1 Average speed and by the end of the ride I just wanted to ride more and next day was 100 perfect… Go AMP OR GO HOME.

I was a bit hesitant to buy this, however, other riders said the same it does help ! It has allowed me to push farther, harder and my legs are not on fire when I go to bed after a Zwift race!! Worth the money for sure !!!

I can’t explain it but Amp has definitely improved my day to day training I have noticed a little less
fatigue in the legs .

This is awesome stuff! I was skeptical...but now a believer, reordering soon!
