“I have been using Endurance 360 for 3 seasons now. Works great for training & racing cyclocross. Better lasting power and faster recovery after sprints.”
Jon BVerified purchase - 2019-05
“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.”
Daniel YVerified purchase - 2018-07
“After just finishing my second of three bottles, I can now say this is a great product! Definitely a performance game changer for this almost 61 year old senior bike rider. A few weeks ago I did my longest ride ever at 110 miles and almost 16k feet of climbing. I surprised myself and did not realize this kind of improvement at my age was possible. Your formulation played a large roll in my improvement due to better performance and recovery during my weekly training cycles. I now look forward to my longest/hardest rides with new found confidence thanks to Endurance360!! Best regards, Mark Boucher SUPRA Functional Food Bar Cycling Team”
Mark BVerified purchase - 2018-04
“Endurance 360 works really well for me, my recovery and race times have all become better since I started taking it. I recommend it for endurance sports.”
Mr pVerified purchase - 2018-03
“Endurance 360 makes all the difference in my training and is a key enabler to hitting my goals. I notice a complete difference in my recovery patterns with endurance 360, as my ability to put in effective workouts day after day is dramatically increased. Without it, I'll miss days of quality workouts in order to recover. Endurance 360 is also key in going to bed with calves that aren't "screaming" at me through the night. It's one of the most important components of my training.”
Scott MVerified purchase - 2018-02
“I was skeptical that I would feel a difference in recovery and performance but after the first few days of using Endurance360 I felt a marked improvement in my workouts, especially after hard workouts. Recovery from bike races is much better and I'm ready to race, totally refreshed, each day for stage races. I'm a true believer in how the product works! I took a break from using it during the "off season" but am now back to daily usage as I start serious bike training for this season's races.”

“"We have had great success with Endurance 360 in both our shops, as well as with our racing team. Our race team focuses on several cycling disciplines and the feedback has been overwhelmingly positive. I can always tell when I am out of Endurance 360, because I start to get panic calls from customers who rely on it monthly!"”

“Why wouldn't you take Endurance 360? You train better, breathe better, feel better. It's for any age. I always say that I am on the Tom Brady/Jennifer Lopez track. Age is only a number.”

L PVerified purchase - 2015-08
“I am convinced that your Endurance360 product contributed to better performance on the bike this year.”
M WVerified purchase - 2015-08
“"I seem to be performing at a high level right now, but that might be because of the 400 mile weeks I am riding. I did win my category at LOTOJA Saturday- so maybe the Endurance360 is working!"”
J LVerified purchase - 2015-08
“I thought the product was great. I had been really struggling the two weeks before LOTOJA couldn't ride at threshold for more than 10 miles and just felt bad. I started taking the supplement about 1.5 weeks before the race and rode without HR monitor because honestly it was too frustrating. On race day I had my HR monitor back on. I felt great and was able to really push myself for most of the day. There was a significantly noticeable improvement in how I felt and how I was riding. The only thing that I really changed was adding Endurance360.”

“I have had 2 of the busiest past weeks at work (I work 12 shifts in the Operating Room - so it's physically demanding). Plus I have worked extra and some additional call shifts....normally those kind of days would leave me a little slow to perk up on my big training days, like yesterday.....but I was totally fine!”

“I used endurance 360 during the healing process after having surgery to put a plate and 7 screws in my humorous that was broke in half. Prior to surgery my arm sat in traction for 7 months without any bone growth, after surgery and adding endurance 360 I had bone growth and was able to get back to sport in 2 months. It's still in the healing process but, with endurance 360 I'm able to push harder with less recovery time. Thank You, Chanda S.”
Chanda SVerified purchase - 2018-02
“As a medical provider and science nerd, I performed a literature review prior to using Endurance360 (funny I know). I reviewed the ingredients individually and found scientific backing for the product claims. I just completed my first training block with the non-caffeinated version and really have noticed a difference. Higher intensity efforts are more sustainable, and my recovery between sessions seems to be more complete.”
D TVerified purchase - 2022-06
“It's good improve my endurance”
Avnish BVerified purchase - 2018-07
“I just retired after a 44 year career. 65 years old. Only riding about 70 miles per week due to work, family, and church responsibilities. Just pulled off the 203 mile 2018 Seattle to Portland in approx 11.5 hours. I was taking two caffeinated 360 tablets in the morning and two non-caffeinated in the evening about two weeks prior to the event. Prior to that it was only 1 of each morning and evening. I really think it helped me get through the ride fairly comfortable. More climbing than expected. About 5500'. I will be starting my 14th LOTOJA this year. Have crossed the finish line 12 times. 1st year was the year it snowed and a couple of years ago I got sick and ran out of gas after descending Geneva. I have been using Endurance 360 for about two years. Really do think it is has been making it possible to somewhat do some challenging rides such as the Ultimate Challenge,Tour de Park City, LOTOJA, and STP with limited training miles. Seems like the older members of Team 360 are always kicking my butt at the SE Senior Games.”
John HVerified purchase - 2018-04
“As an ultra runner I struggle to stay awake around 3am (21 hrs) due to the stress my body is going through around mile 70-80 of a 100 mile race. While running the Wasatch 100 I used the caffeinated Endurace 360 and noticed a huge difference in my ability to stay awake and keep my body loose and relaxed.”

How Endurance360® Compares
Why serious endurance athletes load with Endurance360® instead of Optygen HP, single-ingredient blends, 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). Endurance360 publishes three blend totals rather than per-ingredient splits, as the Label Transparency row above states plainly.
Optygen HP is a registered trademark of 1st Endurance. Amounts derived from published label disclosures.
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.

Early Breakaway Pack
Add race-day nitrate on top of your loading phase. 2x Endurance360 plus 1x Beetroot Pro, Race-Week Timing Plan included.
Get Ahead of Leg Cramps. 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 System
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 blends

Open Loading CalendarSwitching From Another Formula?
Label-by-label breakdowns against the three formulas endurance athletes ask about most, including what each one does better than Endurance360®.
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 string quality workouts together week after week through a training block.
Benefits of Endurance360®
- Increase Muscle Endurance
- Increase Power Output
- Muscle Cramp Support
- Activate Muscle Recovery
- Recover Between Hard Sessions
- Cellular Oxygenation
- Lactic Acid Buffer
- Reduce Muscle Fatigue
- Non-Caffeinated
What's Inside
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).
