How to find out how old you actually are

Your immune system has an opinion about your age. It is rarely the one on your passport.

1. Order the test kit — our link applies the BITCOIN discount at the shop.
2. Four drops of blood on the card. Prepaid envelope. Done.
3. Three to four weeks later: your biological age, read from glycans — which shift years before symptoms do.
4. Take the included 1:1 with a longevity specialist. Change one thing. Retest.

Thirty years of glycobiology, 300,000+ samples, science published in Nature Communications. Don’t trust. Verify — including your age.
