Why we're different

Hold your nutrition to the same standard you hold your training.

Many supplements have a laundry list of ingredients at tiny doses that may not even have any effect other than placebo. We believe that more ingredients does not equal a better product. We think better ingredients at optimal doses equals better products.

FAQ

Straight answers.

Will Third Lung keep me up at night?

No. Zero caffeine, zero stimulants. Train at 8 PM and still sleep at 11.

Is the beta-alanine tingle normal?

Most people who take beta-alanine for the first time will experience an uncomfortable tingle, or prickly itching everywhere, and it usually fades shortly after. As you take the product more, this feeling usually diminishes with each dose. If you can sip the product slower, the tingle is usually less intense.

The rule

If the research doesn't back it, it doesn't go in the tub.

Premium ingredients. Premium dosages. No proprietary anything. No BS.
