Buyer checklist
Glutathione 600 mg buyer checklist: CAS, vial specs, and RUO labeling
Before you buy glutathione 600 mg for laboratory work, check the compound's identity data, the format you are paying for (powder vial or pre-mixed pen), the pack pricing, and the research-use-only labeling. This checklist covers each one and shows what peptide.prof publishes today.
peptide.prof lists glutathione as a 600 mg lyophilized research vial with 1, 2, and 4 pack pricing.
1. Identity: CAS number, formula, and structure
Glutathione is a small tripeptide, so a listing should let you match it to a public chemical record. The reference record is PubChem CID 124886:
| Field | Value (PubChem) |
|---|---|
| Name | Glutathione (L-glutathione, reduced; GSH) |
| CAS number | 70-18-8 |
| Structure | Tripeptide: gamma-L-glutamyl-L-cysteinyl-glycine |
| Molecular formula | C10H17N3O6S |
| Molecular weight | 307.33 g/mol |
If a "glutathione peptide" listing uses a different CAS number, or never names the compound clearly, ask the seller why before you order.
2. Vial specs: what 600 mg means on the page
"Glutathione 600mg" should mean a stated 600 mg of material per vial, with the form named. Here is what the peptide.prof glutathione page states:
| Spec | peptide.prof glutathione listing |
|---|---|
| Form | Lyophilized powder |
| Strength | 600 mg per vial |
| Appearance | White to off-white lyophilized solid |
| Packs | Sold by the pack; 1, 2, or 4 packs |
| Origin | Made in USA |
| Intended use | Laboratory research only. Not for human or veterinary use. |
At the time of writing, the buy box shows 1 pack at $65, 2 or more at $62 each, and 4 or more at $59 each. The live buy box on the glutathione product page is always the source of truth for price and stock.
3. Vial or pen: pick the right format
peptide.prof lists glutathione in two separate formats. Make sure the one in your cart is the one you need:
| Glutathione 600 mg vial | Glutathione Pen 600 mg | |
|---|---|---|
| Form | Lyophilized powder | Single-chamber pre-mixed disposable pen |
| Shipping note | Standard research packaging | Shipped with insulation and cold packaging |
| Listed from (1 pack) | $65 | $105 |
| Product page | Glutathione 600 mg vials | Glutathione Pen 600 mg |
Bacteriostatic water is not included with the vial. It is a separate catalog line (bacteriostatic water, 3 mL and 10 mL) with its own stock status. This site does not publish reconstitution or mixing instructions.
4. Research-use-only labeling
Glutathione is also sold elsewhere as a dietary supplement or as a pharmacy product. A research listing is different: it is a laboratory material purchase, and the page should say so clearly:
- States research use only and not for human or veterinary use.
- Contains no dose, administration, or "protocol" copy.
- Makes no treatment, skin, or health claims.
peptide.prof repeats that framing in the site bar, the buy box, the specifications block, and the FAQ on every product page. For background on the label category, see the RUO peptides hub and the research use page.
5. Purity and lot documentation
Ask whether a lot-level certificate of analysis (COA) is available, and read what the store actually publishes. The peptide.prof homepage trust list says "Batch COA when listed," which is an on-page policy, not a promise that every product shows a PDF at all times. If a certificate is posted, match its lot details and identity result (expected molecular weight about 307.3 g/mol) to your order. If none is shown, do not assume a purity percentage the store has not published.
Glutathione 600 mg buyer checklist you can reuse
- Does the page name glutathione and give CAS 70-18-8 or a formula that matches the public record?
- Is the strength stated as 600 mg per vial, with the form (lyophilized powder or pre-mixed pen) named?
- Are pack prices written as numbers you can quote before checkout?
- Does it say research use only, with no dosing copy or health claims?
- Is there a clear statement about lot certificates, and is any certificate actually posted?
- Are payment methods and the ship-to country stated before checkout?
On peptide.prof, payment goes to the store by Venmo or crypto, and orders ship to a United States address after payment is confirmed.
