Nobody uses it once
That is the only thing everyone does the same way. The trials tested a single application before a single session. Not one person here reports using it like that.
Most people apply it too late.
Every trial that found an effect used the same window: forty to forty-five minutes between application and the hard effort. Rubbing it on at the start line is testing something nobody has studied.
What the trials actually did
The protocol with evidence behind it is 10 ml of gel per leg — thigh and calf — applied 40 to 45 minutes before the first hard effort. That is what Beaven et al. used on seven world-class rugby sevens players in 2025, and what Harnish and Miller used on trained cyclists in 2023. One of those trials found an 8–12% gain in peak power across repeated sprints. The other found nothing. Both used the same window.

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.

Then leave it alone
Warm up, get taped, do your prep. Every trial that found anything left 40–45 minutes before the first hard effort. Nobody has tested applying it at the start line.
45:00
Go
The effect turned up in 6-second maximal sprints repeated twelve times. Steady aerobic work was never tested. If your session has no repeated near-maximal efforts, the evidence does not cover it.
What 45 minutes buys you
One thing, by a small amount. Applying it correctly does not unlock a broader effect — it is the difference between testing what the trials tested and testing something nobody has.
How people actually use it
The protocol above is the tested one: one application, 10 ml a leg, 45 minutes out. It is the only version with a trial behind it — and nobody outside the lab uses it that way. There is no second protocol to give you, because the people using it every day have not converged on one. What follows is the spread of what they actually do.
Two to four times a day is common
Morning, midday, after the evening shower. How much and how often is entirely improvised — no two people describe the same schedule and nobody was given one.
Several days running on one area
When somebody is targeting a specific spot rather than a whole session, they apply it over consecutive days instead of once. Three days upwards is the usual stretch, often dropping to once a day after that.
Reapplied through long days
Across a tournament weekend or a double session, roughly every couple of hours. Six games in four days and four-day competition blocks both show up this way.
Much less on a joint than on a leg
A coin-sized amount on one or two spots, not ten pumps. The 10 ml figure in the trials is for quads and calves, and people scale it down without being told to.
The 45-minute wait is the one rule that survives
Among people using it to train rather than between sessions, the ones who report the most detail still wait the 40–45 minutes the trials used. Applying it on the way out the door is a different protocol and nobody has tested it.
How to read this section
Every trial on record tested a single application before a single session. Repeat dosing, multi-day blocks and application to joints are things people do, not things anyone has studied — and since everybody improvises, the spread above is a description, not a recommendation. Copy any of it and you are running your own experiment, which is fine as long as you know that is what you are doing. The trials are on the evidence page; the people are on the results page.
