Every protocol starts with your questionnaire and bloodwork, is reviewed by our practitioner team before anything is dispensed, and delivered through a reusable injection pen with replaceable cartridges.
Signa is a coaching and education service, not a prescribing pharmacy — we're direct about that distinction. What we do have is a practitioner layer between your data and your protocol.
Every protocol is checked by our practitioner team against your questionnaire and bloodwork for contraindications and dosing logic before anything is dispensed.
If a protocol doesn't fit your file, it's amended or declined — and you're pointed toward your own physician, not talked into a workaround.
If your assigned practitioner is unavailable, another qualified practitioner in our network reviews your file.
We recommend reviewing your protocol with your own physician before starting, particularly if you're managing an existing condition or taking other medication.
Our standards, in full →Most clients begin with a single focus area. Some combine two once their baseline is established. Your practitioner review decides what's appropriate — not a shopping cart.

Peptides bought online usually arrive the same way: a vial, a syringe, and a dosing chart you're left to interpret yourself. Concentration varies batch to batch. Reconstitution is on you.
A Signa protocol starts from your intake, not a shelf, and reaches you through a reusable pen with pre-dosed, replaceable cartridges — removing the reconstitution step and the guesswork that comes with it.
A structured questionnaire — around 10–12 minutes — covering your goals, history, training and current markers.
Upload existing results, or we tell you exactly what to request. No protocol is finalised without a baseline.
Your goals, contraindications and lab markers are mapped against our protocol reference — not a template stack.
Your file is checked by our practitioner team for contraindications and dosing logic before your cartridges are dispatched.
Markers are reviewed every 4–6 weeks. Your protocol changes when the data says it should.
Each cartridge is filled to the amount your protocol specifies — nothing to measure or mix yourself.
A single reusable pen takes a new cartridge at each refill. No separate device to buy or dispose of every cycle.
Every cartridge's batch number corresponds to a Certificate of Analysis in your account.
You see the full cost before anything is dispensed. Figures below are indicative for this design and will be confirmed before launch.
Membership can be paused or cancelled at any time. Nothing is dispensed until your practitioner review is complete. Availability and final pricing vary by country within the EU/EEA.
Purity and identity are verified by a third-party lab, separate from manufacturing, on every batch.
Each cartridge's batch number corresponds to a Certificate of Analysis available in your account.
Cartridges are packed and shipped under temperature-controlled logistics to your address.
Around 15 minutes for the consultation. Practitioner review follows before anything ships.
