Endurance360®Complete
14-Day Loading · Muscle Cramp Support · Faster Recovery
A 2,000mg beta-alanine and creatine blend, plus a 1,200mg cordyceps and rhodiola blend, work beneath the surface. Load for 14 days to support hydration balance and neuromuscular function, key factors in reducing muscle cramp risk, then hold threshold efforts longer and recover faster between sessions.
24 servings per canister
38% less per serving than Optygen HP ($2.67)
How Endurance360® Compares
Why serious endurance athletes load with Endurance360® instead of Optygen HP, single-ingredient stacks, or unloaded protocols.
| Metric | Endurance360® | Optygen HP | Single Ingredient | No Loading |
|---|---|---|---|---|
| Buffering + ATP Blend | 2,000 mg (BA + creatine) | 1,500 mg (BA only) | Varies | None |
| Cordyceps + Rhodiola | 1,200 mg blend | 950 mg total | 200 to 400 mg typical | None |
| 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 |
| Sustained Power | Hours 3 to 6 Protected | Fades past hr 2 | Fades past hr 2 | Fades past hr 1 |
| Cost per Serving | $1.66 | $2.67+ | ~$2.50+ | $0 |
| Label Transparency | Three blend totals, no splits | Six amounts, two blends | Varies | N/A |
Bottom line: Endurance360 is the only column here that pairs creatine monohydrate with beta-alanine, and it carries 1,200 mg of combined cordyceps and rhodiola against the 950 mg Optygen HP discloses, at 38% less per serving ($1.66 vs $2.67). Optygen HP publishes six individual ingredient amounts where Endurance360 publishes three blend totals, so if you need the per-ingredient split in writing, that is the row it wins.

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.

Performance in Motion
See It Unleashed
Cramps End Your Event. Load First.
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. A brief tingling sensation from beta-alanine is normal during this phase.
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

Performance 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.
Recovery Between Sessions
Supports the ATP availability that repeated hard efforts draw on, so you can stack quality workouts week after week through a training block.

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 brief tingling sensation may occur 20 to 30 minutes after a serving during the first week. It is a normal response to beta-alanine and fades as the loading phase progresses.
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'm a 72 yr old, avid cyclist, that still competes. A licensed rider for 50 of those years. I have found that the 'Endurance 360' caffeinated works perfectly for both workouts (training rides), competition and recovery. I can feel the boost in endurance and recovery No aftertaste, no smelly urine or sweat. It gets an easy 5 stars from me."
"I’ve used a variety of sports products over the years. Endurance360 just works. You do need to plan ahead as it truly does not the advertised build period, but once you get to your target event(s) I believe it makes a difference."
"I love these products. I have noticed an increase in endurance and quicker recovery over the last several months that I have been using these during my rides. Thanks for the great product."
"I highly recommend Endurance360 for anyone wanting to take their performance to the next level. This product does exactly what it says it does. Period. Steven Max Parry - Zone Five Racing"
"Been taking Endurance360 for two weeks. Did an 80 mile day with 8,000ft climbing in 90 degree weather...and no cramps or muscle spasms! Super impressed with this product."
"I have been using Endurance 360 for 3 seasons now. Works great for training & racing cyclocross. Better lasting power and faster recovery after sprints."
