According to Real Peptides, a vendor based in the United States, a research-grade NAD+ multi-dose vial is priced at $60.00 (US dollars). By contrast, private clinics and IV bars in the UK charge different amounts before handing NAD+ injections and drips. Between the two scenarios exists a lot of uncertainty regarding the nature of NAD+, its usefulness for humans, and the regulations involved in acquiring NAD+ in the UK.
The reason for establishing this website was that research in the world of NAD injections moves faster than the time evidence catches up. My monitoring of scientific publications, MHRA bulletins, and clinics in the UK is reflected on this website which contains only facts about what clinics offer, what research suppliers have, what research has been conducted, and what remains unclear.
NAD injections introduce nicotinamide adenine dinucleotide into our bodies, a coenzyme present in all cells that plays a crucial role in the conversion of food into energy by our cells. Numerous studies indicate that NAD+ levels decrease with age, and this simple observation is responsible for virtually all commercial interest in this process.
NAD+ is available in intravenous drips and injections at private clinics and med-spas. Some overseas telehealth medications are more advanced and can provide compounded prescription injections or nasal sprays. Oral precursors such as NMN and NR come under a different category, and are sold separately as food supplements.
The clinics claim to sell a narrative about energy and aging. Behind this narrative lies a genuine science regarding cells. However, whether restoring NAD+ from the exterior alters one’s feelings or experience of aging is a different matter. So far, clinical trials on humans have given little claritude on that.
The two routes are not the same product sold in different packaging. A clinic session involves a consultation and a clinician who is responsible for what goes into your vein. A research vial or spray is sold labelled "research use only, not for human consumption", with no consultation and no prescriber.
| Feature | UK clinic drip or injection | Research vial or spray |
|---|---|---|
| Who decides suitability | A clinician at the clinic | Nobody - no consultation included |
| Labelling | Supplied as part of a treatment | Research use only |
| Price | Set by each clinic, varies widely | Vendor list prices in US dollars |
| Quality paperwork | Ask the clinic about its supplier | Third-party certificate of analysis (COA) published by the vendor |
Our comparison of the NAD+ injections research vial and spray sets out the specs side by side, and the page on what a NAD drip session involves covers the clinic side.
Cell model and animal model testing has produced the most convincing results NAD+ research, as there is very little human evidence to substantiate the claims regarding injectable NAD+ benefits in terms of energy, longevity or weight loss.
This does not imply that the clinic marketing is created out of nothing. Instead, it means that the jump from “NAD+ decreases with age in many studies” to “a drip will give you back your energy" has not been verified as it should be done in case of licensed medicines. A page of the clinic saying that it can provide sharper focus or faster fat burning has to refer to an official human trial on this matter but there are very few clinics that can mention one.
Side effects are better described than benefits. Clinics commonly report flushing, nausea, chest tightness or cramping when an infusion runs fast. Our page on NAD injection side effects goes through what is reported and when to stop and seek help.
NAD+ as an injectable is not a licensed medicine, and in the US it is not an FDA-approved drug. In the UK, the Human Medicines Regulations 2012 classify a product by its intended use: if something is promoted to treat a condition, it can be treated as a medicine, with licensing requirements attached.
In April 2026 the Guardian reported that the MHRA was investigating UK peptide clinics making medicinal claims about unregulated products. A "research only" label does not make a product legal to supply for human use and does not mean it was made to medicine standards. Our guide to NAD injections in the UK explains these rules in plain terms.
For side effects from any product, the MHRA's Yellow Card scheme is the place to report.
We discuss and review four research-related products provided by Real Peptides, which is a company based in the United States and prices its products in dollars and offers third-party analysis reports of the products. Furthermore, none of the products involve physician consultation and all of the products are labelled as not fit for consumption.
Real Peptides has a score of 4.2 out of 5 on Trustpilot based on 85 reviews in the past 12 months (last checked November 2026). The vendor's free-shipping threshold amount of $250 is applicable in the US. In the UK, we have not verified the delivery, so make sure that the site confirms the delivery to the UK before placing the order and expect to pay card or currency exchange fees based on the price in dollars, and also remember that the imported goods may be held by the Border Force or charged VAT and customs duty.
Start with the question you actually have. If you are weighing a clinic, read the drip and IV therapy pages first. If you are curious about sprays and vials kept at home, our page on NAD at home lays out what is known and what is not.
If someone has told you a "protocol", read our page on NAD injection dosage before anything else: there is no approved dose for NAD injections, and forum numbers are anecdotes, not evidence. For anything to do with your own health, speak to your GP or pharmacist.
