| Product | Form | Strength | Testing | Shipping | Price |
|---|---|---|---|---|---|
| Real Peptides Glutathione Peptide | Lyophilized powder | 600mg | Third-party COA | — | $40.80 |
| Real Peptides NAD+ Peptide (Multi-Dose Vial) | Lyophilized powder | — | Third-party COA | US stock | $60.00 |
The price of a vial of glutathione is $40.80 for 600mg, whereas a glutathione IV provided in a clinic is priced service which includes all staff and the pharmacy product. So these are not the same transaction. There's a difference between an IV in a clinic, an injection in a clinic and a research vial, which lie in the provider responsible for these and other parameters stipulated by the law for such purchases.
This page places all three side by side for comparison purposes. None of these three are treatments for wellness or skin approved by the FDA, and the research vial is intended for laboratory research only. I focus on the formats themselves, rather than how they should be used by anyone.
The three types fall into two distinct categories: one provides a healthcare service and one does not. The table compares them according to the aspects which customers are most likely to inquire about.

Glutathione IV refers to a type of IV therapy that health and wellness clinics offer. This procedure includes the administration of glutathione, in which medical staff makes use of intravenous methods to inject this supplement directly into the blood.
The appeal for many clients is the setting: someone qualified is present, asks about health history and watches for reactions. The weakness is the evidence. Controlled human trials showing that a glutathione IV delivers the advertised skin or energy benefits are lacking, as we explain on the benefits page.
Request information from a clinic that provides glutathione IV about the source of its product and the personnel present during session. The reputable and good clinic will respond the questions readily.
Many clinics have been found to advertise glutathione IV therapy alongside NAD+ drips. Because of the potential for unwanted effects (e.g. flushing/nausea/chest pain) related to rapid administration, supervision is an important part of the administration process.
The glutathione injection in a medical facility takes less time than the intravenous one and is often cheaper as well. However, just like the latter procedure, it is a healthcare procedure performed by a specialist which entails the necessity of some screening.
The exact claims beneficial attributed to injections are applicable to drips and claims with evidence gap same as for drips. The only difference is that the way it enters the body and the time spent on the procedure is altered. However, the weak claim does not become a strong one through the route taken.
We publish no comparison of "how much" or "how often" between IV and injection, because no approved human dose of injectable glutathione exists. Our glutathione dosage page explains why.
The research vial is a 600mg container that contains freeze dried glutathione from Real Peptides. It comes with a third party Certificate of Analysis (COA) and carries the label ‘not meant for human consumption.’ The research vial has the lowest price amongst the three vials, and it is the only vial that has been manufactured for use in the laboratory rather than by humans.
After FDA's August 2026 warning letters, vendors that pair injectables with dosing charts or bacteriostatic water face scrutiny regardless of their labels. A careful research vendor sells the vial and the paperwork, nothing more.
The useful comparison depends on what you are trying to do. For a lab project, the research vial is the only relevant option and the comparison is between lots, COAs and price, which our glutathione peptide page covers.
your health, it is an either/or situation for whether one should choose a glutathione injection at a clinic. However, that choice is a medical one, and it should be made in consultation with your physician, who will evaluate the scarce evidence against the inherent risks of any injectable substance.
Cost is often the deciding factor people mention, so we break the numbers down on the glutathione injection cost page.
