About us

Your biology. Your protocol. No guesswork.

Personalized Peptides exists because peptide dosing shouldn't be a guess copied from a forum thread. We provide DNA-driven peptide recommendations matched against 500,000+ genetic markers — so your protocol is built from your biology, not from someone else's results.

What we do

Most peptide advice online is generic: the same stack recommended to everyone, regardless of how their body actually processes it. We start from the opposite end. Your DNA carries real signal about how you metabolize compounds, respond to inflammation, recover from training, and age — and that signal should decide what you take, not a bestseller list.

We built Personalized Peptides to read that signal and turn it into a protocol: specific peptides, specific doses, specific reasoning, tied back to markers in your own genome. It's precision over guesswork — the same principle behind personalized medicine, applied to peptide therapy.

How it works

From quiz to protocol.

01

Take the free quiz.

A few minutes on your goals, training history, recovery patterns, and health priorities. That alone generates an initial peptide recommendation ranked against your profile.

02

Order your DNA kit.

A CLIA-certified saliva test shipped to your door. Spit, seal, mail it back — three minutes of effort. We sequence 500,000+ genetic markers across 23 health domains.

03

Get your protocol.

3-4 weeks later, your results arrive. 23 health domains. Two biological clocks. A peptide protocol refined against your DNA — stronger matches at the top, backed by peer-reviewed citations.

04

Retest and refine.

Re-test in 6 months. Track your biological-age delta. See whether your protocol is moving the numbers. Your protocol evolves as your biology shifts.

The science

Evidence, not opinion.

CLIA-certified lab

Every DNA and epigenetic test is processed in a CLIA-certified facility — the same standard as hospital diagnostic labs.

Peer-reviewed evidence

Every peptide recommendation cites published research. We reference real studies, not forum lore. 100+ citations across the catalogue.

99% purity standard

Third-party certificate of analysis on every batch we connect you to. No blind trust — verified purity, documented sourcing.

Who we are

Personalized Peptides is part of the Longr ecosystem — a group of brands building evidence-backed health infrastructure. We share data, standards, and clinical partners across the network.

Our team includes clinicians, researchers, and engineers working to make peptide therapy data-driven rather than anecdote-driven. We're based in New York with lab partners across the United States and European Union.
