What are peptides?
A peptide is a short chain of amino acids joined by peptide bonds. How peptides differ from proteins, which peptides occur in nature, and which items in the catalog are not peptides.

How is a solution prepared?
This is how solutions are prepared in the lab.
Step 1 of 8: Disinfect
The stoppers of both vials are wiped with an alcohol swab.
- Disinfect. The stoppers of both vials are wiped with an alcohol swab.
- Draw up. The needle passes through the stopper of the bacteriostatic water and the plunger draws up liquid.
- Transfer. The liquid runs down the inside wall of the vial with powder.
- Mix. The vial is gently swirled until the solution is clear.
- Done. The solution is ready for use in research.
- Take sample. A new needle passes through the stopper and the plunger draws up part of the solution.
- Sample vial. The solution runs through the septum of the screw cap into a sample vial.
- Analyze. The sample vial goes into the autosampler; the instrument measures the solution in vitro.

About Glutathione
Buy Glutathione from PulseChem
PulseChem offers Glutathione in vials of 1500 mg, with the batch number on the label. Storage and handling follow the label and COA. One vial costs €79.95 including VAT; whether it can ship right now is shown next to the price.
The Glutathione for sale here can be ordered by anyone aged 18 or over who buys for laboratory research, as a guest or with an account. You confirm research use at checkout.
An unusual tripeptide
In most peptides, each amino acid is linked to the next through its backbone. Glutathione is different: glutamate is coupled to cysteine through the carboxyl group of its side chain, the gamma position. PubChem, citing ChEBI, describes it as glutamic acid attached via its side chain to cysteinylglycine; the full name is gamma-L-glutamyl-L-cysteinylglycine.
Cysteine provides a free thiol group (SH). Frederick Gowland Hopkins described the compound in 1921 in the Biochemical Journal and named it glutathione. Its CAS number is 70-18-8.
Purity and COA for every batch
An external laboratory tests every batch of Glutathione: HPLC for purity (≥99%) and mass spectrometry for identity. The free thiol group can oxidize; two molecules then form glutathione disulfide (612.6 g/mol), which stands out as a separate peak in the spectrum. Look up the COA by batch number on Lab results.
Storage and shipping
Keep the vial closed, cool, dry and dark, as the label and COA state. We ship from Europe in insulated packaging with tracking, with a cold pack in warm weather. Delivery takes 1–3 working days within Europe, within the EU only. If your order is received and paid before 3 p.m. Central European time on a working day, we ship it the same day.

Questions about Glutathione
Where can I buy Glutathione?
Glutathione is available from PulseChem in this web shop. The 1500 mg vial costs €79.95 including VAT, and Glutathione is temporarily out of stock. Orders received and paid before 3 p.m. Central European time on a working day ship the same day; delivery takes 1–3 working days within Europe. Every batch comes with a COA.
How is the purity of Glutathione tested?
The purity of Glutathione is measured for every batch by an external laboratory using HPLC, and a batch is released only at ≥99%. Mass spectrometry confirms identity and also shows the disulfide form if it is present. You can find the COA with the batch number on Lab results.
How is Glutathione shipped and stored?
Glutathione is shipped by PulseChem from Europe in insulated packaging with tracking, with a cold pack in warm weather, and only to addresses in the EU. Delivery takes 1–3 working days within Europe. After receipt, keep the closed vial cool, dry and dark, following the label and COA.
What is in a vial of Glutathione?
A vial of Glutathione contains 1500 mg of glutathione, the tripeptide gamma-L-glutamyl-L-cysteinylglycine. The label shows the amount and the batch number. With that number, you can find the COA for your batch, with the purity by HPLC and the identity check.
Background from the knowledge base
What is a COA?
A certificate of analysis tells you what is in a batch and how it was measured. How to read one, and how to check that it belongs to your vial.
What does 99% purity mean?
A purity of 99% tells you about the composition of the peptide, not about the amount in the vial. What the number measures, and what it does not.
