ENDURE X primers the aerobic system and increases blood flow to the working muscles for more aerobic power and faster recovery between intense efforts. Supercharged Collagen provides the vital amino acids to nourish tendons, ligaments, and pulleys as you load these connective tissues throughout your session. 

Using the Endure X + Supercharged Collagen stack before every workout will:

  • Optimize blood flow to the working muscles for more aerobic power and faster recovery between hard boulders, during mid-route rests, and between intense exercises.
  • Increase your power-endurance in climbing long boulders, routes, and throughout your climbing or training session.
  • Provide collagen-specific amino acids (glycine and proline) to the highly stressed connective tissues of your fingers, elbows, and shoulders. Research has shown that consuming hydrolyzed collagen before loading tendons and ligaments increases remodeling and recovery of connective tissues.
  • Long-term usage supports developing stronger, healthier tendons, pulleys, and ligaments...and more powerful, fatigue-resistant muscles.

Combining Endure X and unflavored Supercharged Collagen into a tasty and effective pre-workout/pre-climbing stack has become popular among some of our ambassadors and customers, but it was PhysiVantage Pro Matt Fultz who first promoted the idea to me.

If you don't know of Matt, well, he's one of the strongest, hardest training and climbing, and nicest guys in our sport. Early last summer he messaged me about his daily consumption of Endure X and Supercharged Collagen before every workout and climbing session. Matt has since gone on to have his best climbing season (dozens of V11 to V15 sends) and his fingers remain healthy and stronger than ever!

I'd like to believe this PhysiVantage stack played a role in his success, but who knows for sure? Well, I guess Matt would know...and, honestly, he swears that this stack has significantly benefited his training/climbing since he began using the products one year ago.

Anyway, while I do often add unflavored Supercharged Collagen to my morning coffee, I'm increasingly using "Matt's stack" before every training and climbing session. I simply stir (or shake) one scoop of each into a pint of water and consume it during my warm-up. Why don't you give it a try?

Ultimate preworkout stack

Awesome! I am psyched that there is a dedicated supplementation line up specific to climbing! Look forward to climbing and recovering better with PhysiVantage!

Power Endurance!

It’s almost absurd how much my endurance increased since taking the pre-workout stack. It’s my new not so secret weapon for a long healthy day of climbing at the crag! Thanks so much
