Why Vow exists
Vow Peptides supplies research peptides to laboratories and qualified researchers who need consistent material and paperwork they can check. Every lot is tested by an independent third-party laboratory, and its certificate of analysis is published in our certificate archive before that lot is offered for sale.
A vow is a promise someone can hold you to. Ours is simple: the vial you receive matches the certificate published for its lot, and you can read that certificate before you order.
Sourcing
Everything we sell is made in the USA, by synthesis partners who work under documented quality-management practices. We keep that list of partners short and do not publish their names. What we do publish is the trail: every vial carries a lot number that ties it to the batch it came from and to that batch’s certificate.
A lot is offered for sale only after its certificate of analysis has been received and published. If a lot’s results do not meet its specification, it is not sold.
Quality
Each certificate comes from an independent third-party laboratory and belongs to a single lot. It records the tests run on that lot and the date they were run: purity and identity, with endotoxin and appearance where the panel includes them. Certificates are specific to their lot and are never reused.
To check a vial, find the lot number on its label and look it up in the certificate archive. A certificate reports results on the day of testing; it is documentation for your records, and our terms explain exactly what it does and does not cover.
Handling and storage
Peptides ship as lyophilized (freeze-dried) powder in sealed vials, the form best suited to transit. Shipping & Returns has the details.
When a parcel arrives, move the vials into cold, dry storage away from light; many laboratories keep sealed lyophilized peptides frozen for long-term storage. Temperature swings, repeated freeze–thaw cycles and time all act on a peptide, so handle and log storage under your own laboratory procedures. We do not advise on reconstitution or experimental protocols; those decisions belong to your laboratory.
Research use only
All products are sold for laboratory research use only. They are not for human or veterinary use, not for diagnostic or therapeutic use, and are not a drug, food, or cosmetic.
Buyers must be 21 or older and confirm our research-use terms at checkout. The full conditions of sale are in our terms. Questions about a lot, a certificate or an order are welcome through our contact page; we answer most messages within one business day.
