PeptiStrong® is an innovative, plant based, AI-powered peptide, sourced from fava beans, these peptides are identified using state-of-the-art machine learning research to harness muscle-boosting benefits for workout and performance supplements.*

HMB (beta-hydroxy beta-methylbutyrate), a compound your body naturally forms by metabolizing leucine, offers impressive benefits as a supplement, particularly for supporting muscle health. Research highlights its ability to enhance muscle growth, especially in untrained individuals and older adults starting resistance training, while also reducing muscle breakdown in various scenarios, like during intense exercise or aging.

Additionally, HMB can boost exercise performance, making it a valuable tool for those looking to preserve or build muscle mass. Though its effects may vary based on training status and protein intake, it shines as a support for minimizing loss and promoting gains in specific groups, contributing to stronger, more resilient muscles.*

L-Glutamine, an amino acid naturally present in your body (not formed from leucine, unlike HMB), supports muscle repair, gut health, and immunity. L-Glutamine boosts gastrointestinal wellness, enhances gut barrier function, and speeds recovery from surgery, injury, or intense workouts by restoring glutamine levels depleted during physical stress.

It’s especially beneficial for athletes, those healing, or anyone aiming to maintain a healthy stomach lining and immune system.*

Strength-5 is designed to pair seamlessly with other Xendurance products, enhancing your fitness routine with synergistic benefits. It works hand-in-hand with Creatine-JB, as both boost muscle strength through complementary mechanisms—Strength-5 fuels power and endurance, while Creatine-JB amplifies energy and growth.

Its flavor profile and fine powder blend effortlessly with Hydro, Fuel-5, Fuel-5+, and Xendurance Proteins. Simply toss a scoop of Strength-5 and, say, Creatine-JB into your shaker, add your preferred amount of water, and shake for a smooth, tasty mix—crafted to integrate perfectly with these powders for maximum impact.*

For maximum results, mix one scoop into 8-16 ounces of water or blend it with your go-to powdered supplement—think Creatine-JB or any Xendurance formula like Hydro or Fuel-5. Its light, refreshing flavor makes it a breeze to enjoy before, during, or after your workout.

Just shake it up, and you’re ready to power through or recover strong—it’s that simple and versatile!*

Strength-5’s lemon-lime flavor delivers a crisp, refreshing burst that stands in stark contrast to the harsh, bitter taste of typical amino acid blends.

While most amino mixes leave an unpleasant aftertaste, this zesty, light profile feels invigorating and smooth, making it a welcome relief whether you’re powering through a workout or recharging after one.*

• L-Tryptophan: Fuels the creation of vital neurotransmitters and hormones like serotonin and melatonin, enhancing mood balance and promoting restful sleep.*
