What is the difference between pharmaceutical grade and laboratory use?

Pharmaceutical grade (a.k.a. USP grade) meets the purity specifications of the United States Pharmacopeia and is usually accepted as safe for human use. In general, lab grade products undergo less purification and have not been deemed safe for human use.

What are all the ingredients?

Deionized water and USP-grade methylene blue.

To the seller. Should these bottles have a anti tamper plastic wrap around bottle? The one I received today does not have one.

Each bottle is individually sealed within a poly bag before shipping. If your poly bag is not intact, you can submit a request for a replacement or refund.

Expiration date says sample. Is there an expiration date?

Each bottle is labeled with an expiration date that is two years from the date of the solution's manufacture.
