Identification and supply format for this catalog entry.
Sold by the sealed box of 10 unlabeled vials. One box minimum per line. Per-vial and per-mg figures are the box price divided out for comparison; the box price is the figure charged.
| Strength | Per vial | Per box |

| 5000iu | $19.50 | $195.00 |
| 10000iu | $37.90 | $379.00 |
Each box holds 10 sealed glass vials of lyophilized material in a neutral tray. The vials carry no label of any kind: no compound name, no strength, no lot number. The receiving laboratory identifies the material against the lot certificate of analysis and labels it under its own name and its own quality system. No labeling service is offered.
Material is sold to businesses only and ships within the United States. Why the vials arrive unlabeled · Wholesale supply of unlabeled research peptides
The certificate that ships with a lot reports what the supplier's instrument measured on the supplier's sample: typically identity by mass spectrometry and purity by HPLC as a percentage of peak area. It is a reference point for the receiving laboratory's own incoming inspection.
What a standard certificate leaves out
It is not a release decision, and it is not a statement that the material is safe for any purpose. A standard peptide certificate routinely omits endotoxin, heavy metals, residual solvents and water content, and it says nothing about how the material was handled after the sample was drawn.
