Why it's a great deal

  • Quickly fuels you with glycogen for optimum performance, endurance & recovery. Carb load in 1-2 hours - not several hours before. Sustained-release mechanism energizes you during the duration of your training.

  • Have you ever experienced "hitting the wall" while training or participating in your favorite sport? Thanks to Karbolyn, that search is finally over.

  • Karbolyn is quickly absorbed into the bloodstream like a simple sugar but without the typical spike or crash caused when your muscles run out of fuel.

  • Fast-acting, long-lasting, high-performance fuel

  • Pre-workout: quickly 'carb-load' In minutes not hours

  • Post-workout: replenish muscle glycogen for faster recovery

No regrets

Is the EFX Sports worth it? After a month of daily use, my answer is an easy yes. The quickly fuels you with glycogen for optimum is the standout feature — it performs exactly as advertised and noticeably better than the vitamins, minerals & supplements I replaced. Setup was quick, build quality feels premium, and at around $58 it undercuts comparable vitamins, minerals & supplements at twice the price. If you're comparing options, the EFX Sports is the one to get.

Fine, not amazing

Mixed feelings about the EFX Sports. The post-workout works as advertised, but setup was more fiddly than it should be.
