WHY THE BURN WINS

Your fitness isn’t failing. The burn is forcing you to back off.

During hard efforts, rising acidity contributes to the muscle burn that makes you slow down. Sodium bicarbonate is a proven buffer.

1

You go hard

Intervals, climbs, surges, and race pace demand repeated high-intensity contractions.

2

Acidity rises

The harder the effort, the more the burning sensation builds in the working muscles.

3

Pace fades

You back off—not because you forgot how to suffer, but because the muscle can’t keep producing the same force.

THE 2% APPROACH

Add sodium bicarbonate to the warm-up—without drinking it.

2% is designed to help delay deep muscle burn using a topical roll-on that takes seconds to apply.

Questions before you try it?

When will my order ship?

Typically next business day.

What's the science behind 2%?

2% is built around sodium bicarbonate, an ingredient long studied as an exercise buffer. Instead of asking you to mix and drink it, 2% is applied directly to the working muscles as part of your warm-up. Individual results vary; links to the supporting sodium-bicarbonate research appear above.

When should I use it?

Use it before hard intervals, races, long days, climbs, heavy sets, or any session where muscle burn is likely to limit the effort. Save it for the days where intensity matters.

Can I use it with chamois cream or other products?

Yes! 2% is designed to be compatible with most athletic creams, including chamois creams. For best results, apply 2% first directly to the target muscles (like quads, hamstrings, and calves), let it absorb for a few minutes, then apply your chamois cream as usual. Always patch test first if combining with other topicals, just to be safe.

Does it leave a residue or smell?

2% absorbs quickly and dries clean without a greasy or sticky finish. It has a light mint scent.

How do I apply it?

Remove both lids, twist the cream up, and apply it generously to the muscles you expect to work hardest—such as quads, hamstrings, glutes, or calves. Use the stick to rub it in, then replace both lids.

Is it safe for sensitive skin?

2% is formulated to be gentle and non-irritating for most users. However, if you have especially sensitive skin, test on a small area first.

What if I don’t set a PR?

Give 2% a fair test on your hardest sessions. If you don’t set a personal record within 60 days, contact us within the guarantee window and we’ll refund your purchase. One refund per customer.
