|---|---|---|---|---|
| 25 mg | $114 | $4.56 | +14% | Thymalin (25mg) |

What the laboratory found
No third-party certificate for Thymalin from Biotech Peptides has been located.
That is a statement about the public record, not an accusation. The vendor may test and not publish, or publish somewhere we have not read. What it means for a buyer is that the price above is the only thing established here, and price says nothing about what is in the vial.
Vendors whose certificates you can check yourself lists the ones where that gap is closed.
