MetaGen
How we make our peptides
We are not a reseller. We compound our own peptides in our own licensed facility, and we test every batch.
Most of what is sold as research peptides is bought in bulk from a third-party manufacturer and re-labelled, with the seller trusting that the contents match the label. We work differently. MetaGen compounds its own material in-house and tests every batch, so the quality is something we control and can show you, rather than something we hope is correct.
We compound our own
MetaGen is a compounding operation, not a storefront in front of someone else's product. Our peptides are made by us, in our own facility, instead of being sourced from a bulk supplier and packed under our name. One team is accountable for each compound from production through to the pen you receive. When you buy from a reseller, no one in that chain can truly answer for what is inside the vial; when you buy from us, we can.
Compounded under GMP, in a licensed facility
Our peptides are compounded to Good Manufacturing Practice (GMP) standards in a licensed facility. GMP is the framework that keeps production consistent and controlled from one batch to the next: defined processes, controlled conditions, documentation, and traceability. It is the difference between material made to a standard and material made in a way no one can account for.
Every batch tested, with a Certificate of Analysis
Every batch we produce is tested, and a Certificate of Analysis (COA) is available for it. A COA is the independent lab report that states a batch's purity and identity, so the label is backed by a number rather than a promise. If you are not sure how to read one, our guide on how to read a peptide Certificate of Analysis walks through exactly what to look for. We would rather you check the figure than take our word for it.
Made in pen format, in-house
Most research peptides are supplied as lyophilized powder in vials, which then has to be reconstituted and drawn by hand. We produce our range in pen format, and the pens are filled in-house in the same controlled environment, not outsourced to a separate packer. Keeping the pen fill under the same roof as the compounding means the dose in the pen is the dose we made and tested, with fewer hands and fewer steps between the two.
For laboratory research use only
Everything we make is supplied for laboratory and research use only, and not for human or veterinary use. Our aim is simply to make that research material to a standard you can verify: compounded in-house, produced under GMP, and tested batch by batch, with the paperwork to prove it.
