01
Clean room and controlled environment
Critical stages take place in clean rooms, with filtered air and environmental conditions that are controlled and recorded. Staff enter in dedicated clothing and follow written procedures.
The factory
We make it, so we can show it.
VLS Peptides makes what it offers. This tour follows the plant stage by stage, from the air of the clean room to the laboratory results recorded in each batch's certificate.
A brand with its own plant
Putting on a label is easy. Manufacturing takes something else: clean rooms, calibrated equipment, trained staff and records that can be reviewed at any time. VLS took the long road and produces in its own plant.
That decision has a practical consequence for anyone who uses the pen: every unit has a history. We know which batch it was filled in and which tests it passed.

Documented process
Every stage leaves a record and the procedures are written down.
02
Documented quality
Written procedures, a controlled environment and equipment, and trained staff, with a record of every stage.
03
Traceability
The batch and the code stay with each unit from the filling line to your hands.
The factory
Six stages, one standard
This is how a VLS pen is built, in the order it happens in the plant.
02
Filling ampoules and cartridges
An automated line fills each ampoule with the same volume of solution. That way every unit holds 40 mg in 3 mL, without the variation of manual filling.
03
Sealing the ampoules
As soon as filling ends, each ampoule is sealed hermetically to protect its contents. The seal is inspected before the next stage.
04
Pen assembly
The sealed ampoule is fitted into the body of the multi-dose pen, with its window and selector. Every assembled unit is checked before it goes to packaging.
05
Packaging, batch and code
The pen is placed in its box together with 4 needles of 3.0 mm. The packaging receives a batch number, an expiry date, a verification code and a security seal.
06
Laboratory quality control
Samples from each batch are analysed to confirm identity, purity and content, and the results are recorded in the certificate of analysis.

What the laboratory measures
Before leaving the plant, every batch answers three questions: which molecule it is, how pure it is and how much it contains.
01
Identity
The measured molecular mass is compared with the expected one to confirm that the filled molecule is the one the label declares.
02
Purity
Expressed as a percentage: how much of the analysed material is the main peptide and how much is impurities.
03
Content
Confirms that the amount of peptide matches what is declared.
04
Results in the COA
The results for each batch are recorded in its certificate of analysis.

Why this shows in your pen
- Same concentrationAutomated filling keeps 13.33 mg/mL from one unit to the next.
- Ready to useThe solution arrives prepared. There is no powder to reconstitute and no mixing to do.
- TraceableEvery box carries a verifiable batch and code, with a certificate of analysis for the batch.
- Cold storageThe pen is kept between 2 and 8 °C, at home as well.
Does the pen leave the factory ready to use?
Yes. The solution is filled into the ampoule and the pen is assembled in the plant. There is nothing to mix or reconstitute: you simply fit a new needle before each use.
How do I know which batch my pen is from?
The batch number is printed on the box, alongside the expiry date and the verification code. With that number you can find the matching certificate of analysis.
Is every batch tested?
Yes. Samples from each batch are analysed and the results are recorded in the certificate of analysis (COA). The active-ingredient certificate is published on this site; certificates for other batches can be requested on WhatsApp.
Why does cold storage matter so much?
Because peptides are sensitive to temperature and the quality measured in the laboratory has to be preserved until use. That is why the pen is stored between 2 and 8 °C, at home as well.
