| Creatine Included | Yes | No | No | No |
| Loading Plan | 14-Day Full Saturation | No Structured Loading | Partial Saturation | No Loading |
| Neuromuscular Support | Full Threshold Support | Partial (no creatine) | Partial (BA only) | None |

1. Beta-alanine supplementation augments muscle carnosine content and attenuates fatigue during repeated bouts of exhaustive exercise. (Journal of Applied Physiology).
2. Creatine supplementation improves high-intensity performance across repeated bouts in endurance events. (Journal of Strength and Conditioning Research).
3. Cordyceps Cs-4® is shown to improve aerobic capacity and oxygen utilization during sustained aerobic effort.

14 Days to a Stronger Engine
Week 1 establishes the saturation baseline. Beta-alanine begins loading into muscle tissue, creatine phosphate stores start rebuilding, and the daily habit forms. Most athletes notice nothing during the first week, that is exactly how it should work. The ingredients are accumulating where they matter.
Week 2 is where the shift happens. Carnosine levels cross the threshold that delays the burn at tempo pace. Creatine saturation supports ATP regeneration during repeated efforts. By day 14, the wattage or pace that used to fade in the third hour holds steady. Recovery between intervals tightens. The engine is stronger because you built it, not because you chased a quick hit.
14 Days to Full Saturation
Creatine and beta-alanine are not acute supplements. They build in your muscle tissue over weeks. Here is how the timeline unfolds.
Loading Phase
Days 1-14
5 capsules daily with breakfast
Saturates intramuscular creatine and plasma carnosine. Tingling (paresthesia) from beta-alanine is normal and signals the pathway is active.
Performance Phase
Day 15 onward
5 capsules daily to maintain saturation
Creatine and beta-alanine stores peak. Threshold power and lactic acid buffering are at their highest. VO2 max adaptations from cordyceps compound here.
Race-Day Stack
Race Morning
Pair with Beetroot Pro, 60 to 90 min before start
E360 handles your chronic baseline capacity. BRP delivers the acute nitric oxide spike at the gun. The two pathways do not overlap.
Why Endurance360® Is Different
- Pioneering combination of Creatine, Beta-Alanine, and Cordyceps
- Stimulant free and caffeine free for clean, crash-free performance
- Comprehensive amino acid profile (Beta-Alanine, Creatine, Tyrosine, Methionine, Carnosine, Taurine, Arginine HCL)
- Cordyceps mycelium extract (4:1) and Rhodiola Rosea for aerobic threshold and recovery
- Electrolyte minerals for hydration and mineral balance
- Manufactured in a cGMP Certified facility
- Comprehensive adaptogen and amino acid matrix at a fraction of comparable standalone stacks

Open Loading CalendarPerformance Benefits
Week 1: Establish Saturation
Beta-alanine and creatine begin loading into muscle tissue. Most athletes notice nothing yet, that means the system is working beneath the surface. Consistent daily dosing is the only requirement.
Week 2: The Threshold Shift
Carnosine levels cross the effective threshold. The burn at tempo pace delays. Creatine phosphate stores support ATP regeneration during repeated efforts. This is where you feel the loading pay off.
Maintenance: Hold the Gain
Once saturated, daily maintenance keeps carnosine and creatine stores elevated through your entire training block. Stop dosing and levels return to baseline in 3 to 4 weeks.
Stimulant-Free Performance
Meaningful improvements in power and stamina without caffeine or jitters. Clean performance for athletes who train and race on feel.
Aerobic Capacity Support
Cordyceps mycelium extract (4:1) supports oxygen efficiency across long rides, runs, and races. Pairs with the loading arc for compounded benefit.
Faster Between-Session Recovery
Reduces downtime between hard training days so you can stack quality workouts week after week. Recovery blood flow and ATP resynthesis both improve with saturation.
What's Inside
Benefits of Endurance360®
- Aerobic Capacity
- Increase Muscle Endurance
- Cellular Oxygenation
- Increase Power Output
- Sustain Threshold Efforts
- Endurance Support
- Hydration and Mineral Balance

How to Take Endurance360®
Daily Loading
Take 5 capsules at the same time every day, ideally around breakfast. Allow 10 to 14 days for full absorption. A harmless tingling (paresthesia) may occur 20 to 30 minutes after dosing during the first week. It confirms the beta-alanine is active and fades as your body adapts.
Maintenance
Continue 5 capsules daily through your training block to keep cellular saturation steady. Each bottle contains 120 capsules (24 servings).

Verified Athlete Reviews
"I just started gravel racing last year after being a road only rider and racer. This year I targeted BWR Montana as my event to be reqady for after being sidelined in January for some surgery. In preparing for that event, Beetroot, a strong training program and resolve were my key tools. I finished 2nd in 70-74 age group even with a wrong turn that cost me about 30min on a 6 mile out and back. Beetroot consistently delivers the results I have come to expect."
"as an athlete who is cautious of what I consumer to aid in performance and recovery, Beetroot Pro is the best. I have been using Beetroot Pro for the last 12mths and is definitely the edge during times of high intensity and ability to recover better. The team at Beetroot Pro have certainly but the research and science behind the product, that's why it works so well."
"I’ve taken many different products over the years. BeetRoot Pro has finally given me a clean energy source that has aided in my quick recovery from intense and long activities. I’ve noticed a significant difference in how I feel during and post long rides on the bike. This is a product I can stand behind and will continue to use well into the future."
"Beet Root Pro and E360 are the best products that I have found. Beetroot Pro alone is good but add E360 and you have a really good combo for endurance and recovery. The bundle is the perfect way to buy these products with a price that doesn't break the bank. Great job Beetroot Pro/E360 team!!!!"
"I have been unsung these products for years now, but I just started using Endurance 360+ for intense and/or long training rides and long events. Last week, I set a new PR on back-to-back rides on Big Mountain Loop! I know it is because of these products!"
"Absolutely love this stuff. Take it every day for general fitness and endurance sports. I cycle a ton and never go on a ride without it. But generally this is great for producing nitric oxide which is vital for our overall health and longevity."
