Jeff Tang

I'm Jeff Tang, organizer of Peptide Parties. I host events that bring clinicians, scientists, operators, and curious people into the same room to talk openly about peptides and where health care is going. I also advise companies building in peptides and telehealth, and I share my own health experiments and lab results on my site.

I got started in health with one tweet. In 2023, after winding down Athens Research, the note-taking startup I took through Y Combinator, I asked who wanted Blueprint meals and attached a Stripe link. People paid, so I started cooking in a friend's kitchen and delivering out of a rental van. That became Eat Blueprint, a meal prep service based on Bryan Johnson's Blueprint Protocol, and Bryan Johnson acquired it in 2024.

At Blueprint, I ran business development. I launched the fresh meal business nationwide and built the diagnostics business, with blood tests, epigenetic tests, a microplastics test, and MRI scans. I also helped organize Don't Die Summits in cities like Singapore, Dubai, and New York. Since leaving, I have focused on bringing people together in person, first with testosterone testing parties and now with Peptide Parties in San Francisco and Los Angeles.
