Peptides,
formulated at sea level.

Marina District · San Francisco

A small, deliberate peptide source on the bay. Carefully selected compounds, every product backed by a Certificate of Analysis, and the kind of personal attention that's hard to find online.

How we work

Quiet science,
on the water.

Jetty is a small, focused operation on the San Francisco bay. We carry a deliberately short catalog of research peptides and stand behind every one with a Certificate of Analysis — so you can read what's in the vial before you read the marketing.

01

COA-backed

Every product ships with a Certificate of Analysis — a batch-specific lab report verifying its identity, purity, and quality.

02

A short, considered catalog

We carry a small selection rather than chasing every new compound. The shelf changes slowly, and on purpose.

03

The same people, every time

Small enough that the person answering your message is the person who picked the product. No ticket queues, no chatbots.

04

Made in San Francisco

Based in the Marina District. We pack and send from a few blocks off the water.

Our ethos

We started Jetty because the peptide world felt like a strip-mall pharmacy with a website. We wanted something that read more like a small bakery — one shopfront, the lights on, the same people answering the door.

Open for business —
and the door is open.

We'd rather hear from you directly than have you click through a checkout. DM us on Instagram for what's on the shelf this week, or start a WhatsApp to ask about a specific peptide and place an order.
