01 — Overview

What it is,
and why.

Retatrutide 20mg is the mid-tier progression for clients who have moved through the starter dose and want stronger triple pathway signalling. Your coach guides titration to keep comfort high and output steady.

02 — Mechanism

Small signals.
Big systems.

3 signalling pathways, mapped and led by your coach. Each one does its own job. Together they change the shape of the protocol.

  1. 01
    GLP1R · appetite

    Sustained satiety at the 20mg tier, adjusted by your coach to keep meals comfortable.

  2. 02
    GIPR · nutrient handling

    Supports insulin sensitivity and energy processing as intake patterns shift.

  3. 03
    GCGR · energy use

    Glucagon signalling for metabolic output at the mid-tier, monitored by your coach.

03 — Standard

Built to a higher standard.

Four things we will not compromise on. They show up in every batch, on every order.

01
Coach led

A dedicated coach sets and adjusts your protocol from day one.

02
Research grade

03

04

Hannah M. with their Cambridge Peptides pen at home

Arrived next day, sealed and cold. The pen is so simple to use — I was nervous about self dosing and it took thirty seconds.

Hannah M.Verified · Cambridge
Daniel R. with their Cambridge Peptides pen at home

Packaging was discreet and the batch certificate matched what was on the site. That is what sold me on ordering again.

Daniel R.Verified · Manchester
Priya S. with their Cambridge Peptides pen at home

Ordered before 10am and it landed the following morning. Sits in the fridge next to the coffee, part of the routine now.

Priya S.Verified · London
Mark L. with their Cambridge Peptides pen at home

Six weeks in and the difference is obvious. Appetite is under control and I have not missed a gym session.
