Reading the report
- Purity, mass and endotoxin are three different results. Purity is the share of the sample that is the target compound, mass is how much was measured in the vial, and endotoxin is a separate test.
- Match the batch (SEM05) on the report to your vial and confirm the report on the testing lab's own page, see how to find your batch.
What the vendor says about handling
- It needs bacteriostatic water for reconstitution. Whether water is included is covered in the bacteriostatic water guide.
- With 1 mL of bacteriostatic water the vendor lists a solution of 10 mg/mL.
- Per the listing, it is stable at room temperature for short periods such as shipping, and refrigeration is recommended for longer storage. After reconstitution it must be refrigerated and kept away from direct light.
For the general picture, see the Semax price and legal status guide.
