Tripeptide
Glutathione
A gamma-glutamyl tripeptide sold through the same research-supply channels as the peptides here. Vial masses are an order of magnitude larger than most listings — 600 mg to 1500 mg is typical — so per-milligram figures sit far below the peptide range.

Each row is a single vial of lyophilised powder, read from the vendor's own public store data at the timestamp shown. Kits, capsules, pre-mixed solutions and blends are excluded because they are not comparable per milligram.

Verified batches
Third-party purity results for Glutathione
Blinded retail purchase, labels stripped, RP-HPLC in triplicate against a reference standard, published pass or fail.
No batches published yet — first blinded results in progress
When a Glutathione lot completes testing, this section carries the lot number, the claimed and measured purity, the delta between them, the method, the laboratory and the chain-of-custody note. Read the methodology.

0.2 mg of the labelled mass is not the compound.
Enter a measured purity from a result you trust. VialPost does not supply a default purity figure, because assuming one would defeat the point of measuring it.

Questions
Glutathione — frequently asked
- How is the Glutathione price per milligram calculated?
- The observed vial price is divided by the mass printed on the vendor listing. Only single-vial listings are used; multi-vial kits and multi-component blends are excluded because their per-milligram figures are not comparable to a single vial of one compound.
- Is the cheapest Glutathione listing the best value?
- Not necessarily. Price per milligram assumes the label is accurate. If a vial assays below its claimed purity, the real cost of a milligram of the compound is higher than the sticker figure — which is what the cost-per-verified-milligram calculator on this page shows.
- Has VialPost tested Glutathione?
- Not yet. The verified batch registry is empty while the first blinded retail purchases are in progress. No purity figure for this compound is published on this site until a third-party laboratory has returned a result.
