The

California
Peptide Club

The Schelling Point on the Peptide Science Frontier.

The California Peptide Club is a community for physicians, researchers, founders, and the peptide-curious to educate on the science, protocols, and risks around peptides.

As covered in

Gatherings

IRL gatherings at technology hubs like AGI House and DeSciNYC unite otherwise fragmented industry experts for panel discussions and breakout groups.

Education

The “Peptides 101” series lifts the veil and educates on the science, risks, protocols, industry players, commercial opportunities, and open research areas.

Chapters

We’re running communities in New York, San Francisco, and Los Angeles.

The case for peptide adoption.

Peptide adoption raises both the floor and the ceiling: We can combat metabolic disease and unburden the healthcare system, and also achieve peak performance, recovery, looks, and health.

The industry is getting demystified. The FDA is weighing which peptides compounding pharmacies may keep making, GLP-1s have moved into everyday medicine, and questions that used to live in anonymous forums now get asked out loud, by physicians, researchers, and builders.

We’re supporting initiatives that bring clarity into the efficacy and safety of popular peptides through proteomic blood tests and studies.

We care about the future of personalized health. We're not a wellness group.

We are building for peptide science what Florence was for the Renaissance and Bell Labs was for the information age.

Now we're taking it one step further and bringing it to a global level.

We are creating the infrastructure layer for regenerative medicine, one that enables effective research, AI-enabled drug discovery, clinical trial recruiting, education and media, and purposeful capital allocation.

To a decade of personalized medicine,
