Quality System

Quality Through
Systems

Quality is not a claim. It is a system — identification, traceability, documentation, handling and verification, applied the same way to every release.

01 / Framework

The Sterling Quality Framework

Five commitments define the framework. Each one is operational — something the company does on every batch, not a slogan.

Batch Documentation

Every batch is released with an identifying reference and supporting documentation that remains available for its lifetime.

Quality Control

Structured review checkpoints govern how products are received, handled and approved for release.

Product Traceability

Batch identities link each vial to its records, so any product can be placed within its history.

Controlled Handling

Storage and handling follow defined procedures designed to protect product integrity at every stage.

Consistent Presentation

Uniform vials, labelling and packaging across every division of the catalogue.

02 / Identification

Product Identification & Batch Traceability

Each release is assigned a reference in the Sterling register format before it moves. The reference is printed on the vial and its packaging, and every later record attaches to it.

ST-RTA-260801

ST: Sterling register prefix
RTA: Product code — Retatrutide
260801: Release sequence — 1 August 2026

03 / Documentation

Documentation

Supporting documentation is filed when a batch is released and remains retrievable for the batch's lifetime. These are the artefacts behind every reference.

Batch Record

The file opened when a release is approved: product identity, batch reference, release date and the documentation set filed with the batch.

Release Summary

PER BATCH

A summary of the quality review outcome for the batch, filed alongside the record at release.

Handling & Storage Note

PER PRODUCT

Product-specific storage and handling guidance, shipped with the product and listed on its catalogue page.

Documentation availability is stated per batch through the verification register. Partners retrieve filed documentation through Sterling Track or their Sterling contact.

04 / Handling

Handling, Storage & Packaging

Integrity is protected by procedure — from controlled handling through storage conditions to the packaging that carries each reference forward.

Handling

Defined procedures govern how products are received, moved and held, protecting integrity between release and delivery.

Storage

Lyophilized vials are held refrigerated at 2–8 °C and protected from light. The same guidance ships with every product.

Identification

Every vial is labelled with its product identity and batch reference in the Sterling register format.

Packaging Control

Uniform packaging protects product in transit and carries the batch reference through to the final recipient.

05 / Verification

Every Reference Is Checkable

The register that assigns batch references also answers for them. Any holder of a Sterling product can resolve its reference online.

06 / FAQ

Questions, Answered

What does a Sterling batch reference look like?

Batch references follow the Sterling register format: an ST- prefix, a product code and a release date sequence — for example, ST-RTA-260801. The reference is printed on the vial label and its packaging.

How do I verify a product?

Enter the batch reference from your vial label into the verification tool on the Verify page. The register returns the product identity, batch status and documentation availability for that release.

What documentation accompanies a batch?

Each release is filed with its batch record and supporting documentation. Availability is shown per batch through the verification tool, and partners can request retrieval through their Sterling contact.

How should products be stored?

Lyophilized vials should be stored refrigerated at 2–8 °C, protected from light, and kept sealed until use. Product-specific guidance is listed on each catalogue page.

Who can access partner documentation?

Verification is open to anyone holding a batch reference. Extended documentation retrieval is provided to approved partners through Sterling Track and partner support.
