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

Every released batch has a record on the Sterling register. What is on file for a batch attaches to that record — and only what is on file is shown.

Batch Record

The entry opened when a batch is released: product identity, product code, batch number, release date and record status.

Analytical Data

WHERE AVAILABLE

Batch-specific analytical results appear on the batch’s verified record when a result exists. Sterling publishes no figure that is not tied to a batch.

Handling & Storage Note

PER PRODUCT

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

What is held for a batch is shown on its verified record. Nothing is listed that is not on file.

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.

Arrival

How Your Products Arrive

Sealed, labelled and traceable — what a Sterling delivery is, from the vial to the outer packaging.

Batch traceability

Every vial linked to its batch record.

Every vial carries its register reference, connecting it to batch records and documentation.

Sealed presentation

Crimp-sealed glass presentation.

Batch record

Resolves to its record on the register.

Every vial resolves to its batch record on the Sterling register.

Controlled packaging

Packed to protect product integrity.

Products packed to protect integrity in transit, with defined storage guidance included.

Discreet delivery

Clean, careful outer presentation.

Plain, careful outer packaging — the register reference lives inside, not on the box.

05 / Verification

Every Reference Is Checkable

The register that assigns batch numbers also answers for them. Any holder of a Sterling product can resolve its verification code 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 verification code from your vial label on the Verify page, or scan the label’s QR. The register returns the product identity, its batch and the record’s status.

What is recorded for a batch?

Each released batch has a register entry: product identity, product code, batch number, release date and status. Batch-specific analytical data is shown on the record where a result exists.

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 verify a product?

Verification is open to anyone holding a Sterling product. Approved partners also reach the register from inside Sterling Track.
