About us

A practitioner answer to a Grey Market.

Most peptide protocols sold today arrive one of two ways: a Grey Market vial with no oversight at all, or a full medical prescription that assumes you already have a diagnosis. Signa exists for what sits between the two: a protocol built from your own data, checked by a qualified practitioner, and delivered through one reusable pen instead of a shelf of vials.

Operating principles

Four commitments we built the platform around.

Review

Practitioner-reviewed, always

No protocol reaches you without a practitioner checking it against your questionnaire and bloodwork first. No exceptions for speed.

See how review works →
Autonomy

Practitioner autonomy

Our practitioners retain full independent judgement. They can amend or decline anything they consider inappropriate for your file.

Testing

Independent quality

Every batch is tested for sterility, endotoxins, identity, purity and heavy metals before release. Certificates upload to your account automatically.

Origin

Built on what we already do

Signa didn't start from a spreadsheet of trending compounds. It started from bloodwork-led coaching work we were already doing, extended to peptides specifically.

Our story

From coaching practice to its own platform.

01

The gap

Clients kept arriving with peptides they'd bought online themselves: no practitioner review, no testing paperwork, and a dosing chart they were left to interpret alone. The alternative wasn't better: a full medical prescription pathway that assumed a diagnosis most of them didn't have.

02

Where it started

Signa grew out of Nabō Wellness, a longevity coaching practice built on bloodwork-driven protocols for training, recovery and hormonal health. The same rigour applied there (test, review, adjust) was the obvious starting point for peptides specifically.

03

The platform

Signa Peptide became its own practitioner-led platform: a structured questionnaire and bloodwork intake, independent practitioner review before anything ships, and delivery through one reusable pen with protocol-matched cartridges instead of a shelf of vials.

Two places to look before you start.

How practitioner review works

Every file is checked by a qualified practitioner before anything is dispensed, and they retain the final say, never an algorithm.

Start with a practitioner, not a guess.

Every protocol begins with your questionnaire and a full blood panel, reviewed by a qualified practitioner before anything is dispensed, then rechecked every four to six weeks as your markers move.
