Rub it on your legs 45 minutes before training. No four-week loading phase, nothing to swallow. Tested on world-class rugby sevens players in a triple-blind trial: against a placebo that tingled exactly the same, the gel added 156 watts of peak power in the seventh sprint — right when legs are already cooked.
Every batch screened for banned substances. If you get tested, nothing else on this page matters until this does.
Ready in 45 minutes
Beta-alanine takes four weeks of daily dosing to raise muscle carnosine. This takes one warm-up.
Nothing to swallow
Goes on the quad and the calf. No gut, no beta-alanine tingle, no timing it around a meal.
Beat a menthol placebo
The 2025 trial gave the placebo the same menthol. Both legs tingled; the players could not tell which was which. The gel still won on peak power — 5–10% in the authors’ summary.
The buffer
Carnosine
A dipeptide your muscle already uses to mop up the acid that builds during hard efforts. It is the ingredient every trial studies, delivered through the skin over the working muscle.
The carrier
Magnesium
Magnesium sulfate in the base. Its job is to help carry the carnosine in.
The cooling
Menthol 1.25–1.5%
The active ingredient on the label — a topical analgesic for minor muscle aches, and the tingle you feel. The 2025 trial gave its placebo the same menthol, so the power gain came from something else.
45 minutes between the gel and the first hard effort — exactly what the athletes in the trials did. It fits inside the warm-up you already do, so it is working by the time the session gets hard.

Ten pumps a leg
Quad and calf, skin clean and dry. The trials used 10 ml per leg. Sweat and body lotion sit between the gel and you, so wipe down first.
40:00
Then leave it alone
Warm up, get taped, do your prep. Every trial left 40–45 minutes before the first hard effort — that is the window the gel is built around.
45:00
Go
The trial measured it across twelve repeated 6-second maximal sprints, and the biggest single gain came in sprint 10 — deep into the session. Sprints, intervals, rounds, shifts: repeated hard efforts are where it earns its place.
The newest trial is the strongest: independent, peer-reviewed, triple-blind, with a placebo that had the same menthol so players could not tell which gel they had. Its authors summarise peak power in repeated sprints as 5–10% higher, in world-class rugby sevens players.
In the test that matters, yes. Seven world-class rugby sevens players, triple-blind, gel against a placebo with the same menthol: peak power went up 5–10% in the authors’ own summary, with the biggest single jump late in the session. Every study is on our evidence page. The quickest way to know for you is to try it: LactiGo comes with a 30-day money-back guarantee.
Is it just the menthol?
No — and that is exactly what the 2025 trial was built to rule out. The placebo was a gel with 1.25% menthol added to match the smell and the tingle. Both felt the same, so the players could not tell which one they had. Peak power was still higher on the carnosine days.
Why does the brand say 4% and you say 5–10%?
Different tests, same direction. The 4% is from a 2016 field test in Serie A footballers: three all-out 1000 m runs, 4% faster on average. The 5–10% is peak power from a 2025 triple-blind trial on world-class rugby sevens players, run independently and published in a peer-reviewed sports nutrition journal. Both are on the evidence page.
How much do I use and when?
10 ml per leg — thigh and calf — 45 minutes before the hard part. That is exactly what the athletes in the trial did, so stick to it.
Can I use it if I get drug tested?
It carries Informed Sport certification, which means every batch is screened for banned substances. Check your batch number on the Informed Sport site before you compete.
Will it help with soreness or recovery?
The label use is temporary relief of minor muscle aches — that is the menthol at work. Faster recovery between sessions is what people mention most in their own reports; read them on our results page. Individual experiences, not a guarantee.
Where do your numbers come from?
Every number on this site links to the paper it came from, so you can check any of them in a click. Then try it yourself — the 30-day money-back guarantee covers you.
The same molecule is sold as a sports gel and as a skincare active, at concentrations two orders of magnitude apart. Which one you want, and what each can actually show.
Yes — for repeated high-intensity efforts. A triple-blind trial on world-class athletes, an early field test, absorption data, and what athletes report.
Hard rolls are repeated near-maximal efforts — exactly what the rugby sevens trial tested. What carnosine gel does for grapplers, and how to use it on the mats.
