About PepXLabs
We supply lyophilized research peptides and blends to laboratories, universities and independent researchers, with clear specifications and lot-level documentation behind every vial.
For laboratory research use only
What we believe
Every PepXLabs lot is sent to an independent, accredited laboratory before it is listed. Lots that test below 99% purity never go on sale, and every certificate is public, searchable by the lot number printed on the vial.
We keep our product pages just as plain: the sequence, molecular formula and weight, CAS number, form and storage conditions for each compound, plus the publications it appears in. No hype, and no claims beyond what the data shows.
Purity by HPLC, identity by mass spectrometry, plus content, water and safety screens on every lot.
Every result is public. Look it up by the lot number on your vial, including past lots.
Sequence, formula, molecular weight, CAS number and storage on every product page.
Our compounds are supplied for in-vitro laboratory research. We don't give dosing or medical guidance.
Insulated, tamper-evident packaging with tracking, and shipment protection on every order.
Ask about a lot, a method or an order and hear back within one business day.
Independent testing
Samples from each production lot go to an ISO/IEC 17025 accredited laboratory, which runs the same panel every time: purity, identity, net peptide content, water content, appearance, endotoxin and heavy metals.
The lab is named on each certificate, and the certificate is linked to the lot number printed on every vial.
