Goal
Longevity
The peptides readers look up for longevity, and whether each can be prescribed or compounded in the U.S. today. Every status below names the FDA document it rests on.
Prescribable now
A coenzyme every cell uses to make energy, now sold as injections and nasal sprays. It may be compounded; the human evidence for giving it directly is two small infusion studies. Read the NAD+ guide
Nicotinamide Adenine Dinucleotide (NAD) is in 503A Category 1 (bulk drug substances under evaluation), covered by FDA's interim compounding policy (list updated May 14, 2026).

The body's own antioxidant, sold as injections, sprays and tablets. Taken by mouth it raises the body's stores while you take it; in the trials that tested a disease outcome it did not beat placebo. Read the Glutathione guide

Ordered by how many of these peptides each seller prescribes, then by name. A partnership never changes the order.
Research only
These are not on an FDA list that allows compounding, or we have not yet read their status. We cover the research on them and link no seller.
MOTS-c
Research only
On no 503A list (not in Categories 1–3 of the May 14, 2026 update). The FDA's compounding advisory committee voted 7–5 (two abstentions) in July 2026 to favor listing it; the vote is a recommendation, not binding on the FDA, and pharmacies may not compound it until final rulemaking.

Research on longevity
- Dihexa: The Animal Research and the Retracted Key PaperDihexa has never been tested in people. Its rat data come mostly from one lab, an independent 2024 study found no benefit, and the 2014 paper explaining how it works was retracted in 2025.
- Does NAD Cause Cancer? What Human and Animal Studies ShowCancer cells depend on NAD+, which is why the question comes up. No human study has measured cancer risk on NAD+ or its precursors, and the mouse studies point in both directions.
- NAC vs Glutathione: Which One Raises Glutathione in People?NAC hands cells the building block they run short of; glutathione capsules try to deliver the finished molecule. Here is what the trials measured for each, including the one small head-to-head.
- NAD for Parkinson's: What the Human Trials Have Found So FarAn oral NAD+ precursor raised NAD+ in the blood and brain of people with Parkinson's in two small, month-long trials. Whether it helps symptoms is still unanswered, and injected NAD+ has not been tested.
- Glutathione for Chemotherapy Neuropathy: What the Trials FoundSmall trials found less nerve damage when glutathione was infused before cisplatin or oxaliplatin. The largest trial, on paclitaxel and carboplatin, found none, and ASCO recommends no preventive agent.
- Semax: what has actually been tested in peopleSemax has real human studies behind it, which is rare on this shelf. They are also small, Russian, largely uncontrolled, and one is not the randomized trial PubMed files it as.
- SS-31 peptide: the phase 3 result sellers do not mentionSS-31 is elamipretide, the best-tested compound on this shelf. Its phase 3 trial randomized 218 people and missed both primary endpoints.
- Epitalon Benefits: Each Claim and the Study Behind ItThe telomere result is real and sits in a dish. The lifespan and survival figures come from a pineal extract, in flies and mice or in an unrandomized cohort of people over 60, and the eye result is a series with no control group.
- Longevity Peptides: What the Human Evidence Shows for Each OneNAD+ precursors raise NAD+ and change little else; oral glutathione raised body stores 30 to 35% over six months; a GHRH analog raised IGF-1 117% in 152 older adults. Epitalon and MOTS-c have no human trials at all.
- NAD+ and Glutathione: The Biochemical Link, and Whether the Pair Has Been TestedCells use NAD+ to make NADPH, the fuel that recycles glutathione, so the pairing has a real pathway behind it. No trial has given the two together, and the closest human evidence is two small trials of a precursor mix.
- Peptides for Anti-Aging: What Human Studies Show for Skin, Growth Hormone and NAD+Oral collagen peptides have the most trials, for skin hydration and elasticity. Growth hormone-releasing peptides and NAD+ precursors changed hormone and NAD+ levels in older adults, without shown effects on aging, and epitalon rests on cell studies.
- NAD+ Benefits for Skin: What Studies of NAD+ and Vitamin B3 ShowSkin loses NAD+ with age, and vitamin B3 forms that the body turns into NAD+ have real skin results, including fewer skin cancers in high-risk adults. NAD+ itself has not been tested for skin.
- Peptides for Energy: What Human Studies Actually MeasuredThe studies behind peptides sold for energy measured fatigue, strength or function, not energy. NAD+ levels rise on a precursor without fatigue improving, semaglutide cuts both ways, and MOTS-c is a mouse result.
- Glutathione for Liver Health: What the Fatty-Liver Studies ShowThe liver relies on glutathione to neutralize toxic drug byproducts, but the studies of taking glutathione for liver disease are small, uncontrolled pilots.
- NAD Dosage: What IV, Injection and Oral Studies Actually UsedNAD+ has no label dose. Human studies have given it by vein at 10 to 750 mg, but none in PubMed has tested a shot under the skin. Its oral precursors raised blood levels within weeks.
- Glutathione Dosage: What Oral, IV and Nasal Trials Actually GaveCompounded glutathione comes with no approved dosing label. Studies gave 250 mg to 1,000 mg a day by mouth, 1,400 mg three times a week by vein, and up to 200 mg three times a day into the nose.
- NMN vs NAD: How the Precursor and the Molecule Itself Compare in Human StudiesNMN is a building block the body turns into NAD+. It is sold as an oral supplement and has randomized trials; NAD+ itself is compounded for injection or IV and has far fewer. No trial has compared them directly.
- Epitalon: What the Telomere Claims Rest OnThe telomere results come from cells in a dish, and the human survival studies used a different substance. The FDA found no clinical data supporting epitalon's safety in people.
- Glutathione for Skin: What Trials of Oral, Topical and Injected Forms FoundPills and lotions lowered skin melanin readings modestly in small trials. The one placebo-controlled IV trial missed significance, and a 2025 review calls IV use for lightening contraindicated.
- Glutathione Injections: What the Evidence ShowsOne placebo-controlled trial for skin lightening, which missed significance. Two FDA alerts on contaminated ingredient. What the rest of the record says.
- Glutathione Side Effects: What Injection, IV and Oral Studies ReportedOral glutathione was well tolerated in trials. IV glutathione was too, but contaminated supplement-grade products caused serious reactions. Inhaled, it narrowed the airways in asthma.
- Liposomal Glutathione: Does Oral Glutathione Raise Levels in the Body?A single oral dose barely registered in 1992. Six months of daily glutathione raised stores 30% to 35%. The liposomal data are two small studies without a placebo arm.
- MOTS-c Dosage: What Mouse and Human Studies Used, and Why No Dose Is SetEvery published MOTS-c dose was given to rodents. The only finished human trial used an analog and never posted its doses or results, so no human dose exists.
- MOTS-c: What the Research Shows in Mice and in PeopleStrong mouse data on insulin resistance and running capacity. In people, one study of ten men who made their own MOTS-c while exercising, and no trial results yet.
- NAD+ Injections: The Benefits Claimed, and What Studies in People MeasuredTwo small intravenous studies are the human evidence for NAD+ given directly. Neither measured energy or aging, and no study has tested injections under the skin or nasal sprays.
- NAD IV Therapy: What Studies of Intravenous NAD+ in People MeasuredDrip clinics sell NAD+ for energy and aging. The studies in people measured what happens to it in the blood, how the drip feels, and one heart trial. None tested the wellness claims.
- NAD Nasal Spray: What the Evidence Shows So FarNo human study has tested an NAD+ nasal spray. One mouse study, a general case for the nasal route, and human data on other routes are what exists.
- NAD Patches: Can NAD+ Get Through the Skin?NAD+ is larger than the size skin normally lets through, and no published study has measured NAD+ in human blood after a patch. The delivery studies all broke the skin barrier first.
- NAD Side Effects: What Injection, IV and Oral Precursor Studies ReportedIV drips caused stomach symptoms and chest pressure during the infusion. Shots under the skin have never been studied. Oral building blocks have randomized trials with clean short-term records.
