Testing is performed by pH Solutions Lab Inc. of Monrovia, California, an independent laboratory ISO/IEC 17025:2017 accredited (A2LA R243 · PJLA Testing #84351). Each certificate carries a scan-to-verify code that opens the laboratory’s own copy.

From the batch to your bench

  1. The lot code is assigned in production. Registered while the batch is still being made, long before any of it leaves the facility.
  2. It is printed on the vial and on the box. Next to a QR square that encodes the same code.
  3. The code opens that batch’s certificate. Scan the square, or type the code into the certificate library. You get the laboratory report for the batch in your hand, not an average and not a representative sample.

Before you order

Questions researchers ask

What exactly arrives when I order PT-141?

One sealed, light-protected vial per unit, holding lyophilized powder in the strength you select (5mg and 10mg), inside protective outer packaging. The label carries the lot code for the batch that vial came from, printed beside a QR square that opens that batch’s certificate of analysis.

How should it be stored once it arrives?

Keep the sealed vial at room temperature, dry and out of direct light. The catalog storage line for PT-141 reads: Room temperature, protected from light and moisture. The handling guidance for the exact batch you receive is printed on the vial label and repeated on its certificate.

How pure is it, and who does the testing?

Every catalog compound is manufactured to a ≥99% purity specification by HPLC. Testing is performed by pH Solutions Lab Inc. of Monrovia, California, an independent laboratory ISO/IEC 17025:2017 accredited (A2LA R243 · PJLA Testing #84351). Each certificate carries a scan-to-verify code that opens the laboratory’s own copy. Every lot is released against its own certificate of analysis rather than a generic spec sheet reused across batches. Browse the certificate library
