Compounded Longevity Medicine: Rapamycin, NAD+, Peptides & More
Summary: "Longevity medicine" refers to a group of compounds — including rapamycin, NAD+, glutathione, growth-hormone-supporting peptides like sermorelin, copper peptides like GHK-Cu, methylene blue, and metformin — that researchers are studying for their potential to support healthy aging. Many are available as compounded, prescription-only preparations in forms like capsules, troches, nasal sprays, and creams. It's a genuinely exciting field, but it's important to be clear-eyed: several of these compounds have strong evidence in laboratory and animal studies and limited, emerging, or still-investigational evidence in healthy humans. They're used only when a prescriber determines it's clinically appropriate.
We think you deserve the honest version — the promise and the caveats — so you and your prescriber can make informed choices.
What is "longevity medicine" (geroscience)?
Geroscience is an emerging field focused on targeting the underlying biology of aging — rather than treating one disease at a time — with the goal of extending healthspan (the years of life spent in good health). Reviews of the field consistently identify a handful of compounds as leading candidates: rapamycin, metformin, NAD+ precursors, and senolytics. In model organisms, several reliably extend lifespan and healthspan; translating that to humans is where the science is still developing. (Geroscience review, PMC/NIH)

Rapamycin: the most-studied longevity candidate
Rapamycin reliably extends lifespan by more than 10% across multiple model organisms — worms, flies, and mice — by inhibiting the mTOR pathway, a central regulator of cellular growth and aging. That reproducibility is what put it at the center of longevity research. (mTOR/rapamycin review, PMC)
The honest caveat: in healthy humans, the clinical evidence that low-dose rapamycin extends lifespan or delays age-related disease remains unestablished. Some trials in older adults have shown intriguing signals — stronger immune responses and fewer respiratory infections — while chronic use carries real risks such as increased infections and elevated lipids. That's why it's used only under close prescriber supervision, typically in low, intermittent dosing. We compound it as capsules. (Aging (Aging-US) analysis)
NAD+ and cellular energy
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to energy production, DNA repair, and the activity of longevity-associated enzymes. Levels decline with age, which is why NAD+ and its precursors are among the most talked-about longevity interventions. We compound NAD+ in several forms — nasal spray, troche, topical cream, and injection — to fit different prescriber protocols. Human clinical data are still emerging, so it remains an investigational, prescriber-directed therapy. (Read our NAD+ guide →)
Glutathione: the master antioxidant
Glutathione is the body's most abundant intracellular antioxidant, involved in neutralizing oxidative stress and supporting detoxification. Because oxidative stress is one of the recognized hallmarks of aging, glutathione is popular in longevity and wellness protocols. We compound it as a nasal spray and a troche. Its antioxidant role is well established; specific anti-aging outcomes remain investigational.
Growth-hormone peptides: sermorelin
As we age, natural growth hormone secretion declines. Sermorelin works by stimulating the pituitary to release the body's own growth hormone, rather than introducing growth hormone directly — an approach prescribers may consider for energy, recovery, and body-composition support. We compound it as troches, a nasal spray, and an injection. Anti-aging applications are investigational and prescriber-directed. (Sermorelin troche guide →)
GHK-Cu and VIP
GHK-Cu, a naturally occurring copper peptide, has strong evidence for skin and tissue repair and is also explored more broadly for regenerative and anti-aging signaling. We compound it as creams, scalp solutions, a troche, and a nasal spray. VIP (vasoactive intestinal peptide) is studied for immune modulation and inflammatory balance and is compounded as a nasal spray. Systemic longevity uses of both remain investigational.
Metabolic longevity: metformin, methylene blue, and others
Metformin — a widely used, well-tolerated diabetes medication being formally studied for its effects on aging (the concept behind the "TAME" trial). We stock it in IR and ER tablets.
Methylene blue — an old, well-characterized compound of interest for mitochondrial and cognitive support, compounded as capsules. (Methylene blue guide →)
Resveratrol — a plant antioxidant popular in longevity circles for its interaction with sirtuin pathways; human evidence is limited.
(Some clinics also ask about amlexanox, a metabolic compound studied for insulin sensitivity. Ask us about current availability, as our catalog evolves.)
Why honesty is the point here
Longevity is a field full of hype and bold marketing. As a pharmacy, we'd rather earn your trust than oversell. Many of these compounds are investigational for anti-aging purposes, provided only pursuant to a valid prescription, and are not proven to extend human lifespan. A knowledgeable prescriber weighing the current evidence — not marketing — should guide any decision. That approach also happens to be the safest one for your health.

Frequently asked questions
Does rapamycin extend human lifespan?
It reliably extends lifespan in animals, but the evidence that it extends lifespan or delays disease in healthy humans is not yet established. It's investigational for this use. (Aging-US)
What's the difference between NAD+ and glutathione?
NAD+ is a coenzyme central to cellular energy and repair; glutathione is the body's master antioxidant. They support aging biology in different ways and are sometimes used together under prescriber guidance.
Are these longevity compounds FDA-approved for anti-aging?
No. Compounds like rapamycin, metformin, and methylene blue are approved for other medical uses; their longevity applications are investigational and prescriber-directed. Peptides like sermorelin, GHK-Cu, and VIP are compounded and investigational for these purposes.
Do I need a prescription?
Yes. All of these are prescription-only.
