NAD+ (Nicotinamide Adenine Dinucleotide) vs SS-31 (Elamipretide)
NAD+ (Nicotinamide Adenine Dinucleotide) and SS-31 (Elamipretide) are both longevity peptides, which is why they get recommended interchangeably — but they are different compounds with different origins. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

SS-31 (Elamipretide)LongevityAt a glance
| NAD+ (Nicotinamide Adenine Dinucleotide) | SS-31 (Elamipretide) | |
|---|---|---|
| Category | Longevity | Longevity |
| Typical route | SubQ (or slow IM) | SubQ |
| Shelf life once mixed | ~30 days | ~30 days |
The differences that actually matter
Both are classed as Longevity peptides, so they get compared constantly and are often researched for overlapping reasons.
Route of administration differs — NAD+ (Nicotinamide Adenine Dinucleotide) is typically subq (or slow im), SS-31 (Elamipretide) is typically subq. That alone changes how convenient each one is to keep up with.
What NAD+ (Nicotinamide Adenine Dinucleotide) is
Nicotinamide Adenine Dinucleotide (NAD+) is not a receptor ligand in the traditional sense, but rather a crucial coenzyme involved in fundamental cellular biochemistry. Additionally, NAD+ serves as a vital substrate for enzymes like sirtuins (SIRTs), poly(ADP-ribose) polymerases (PARPs), and CD38, which are integral to DNA repair, gene expression, immune function, and cellular aging processes. Its intracellular levels are dynamically maintained through synthesis and recycling pathways, crucial for sustaining variou
What SS-31 (Elamipretide) is
SS-31, also known as Elamipretide, is a small, aromatic-cationic peptide designed to selectively target mitochondria. It primarily localizes to the inner mitochondrial membrane where it interacts with cardiolipin, a unique phospholipid essential for mitochondrial structure and bioenergetics. By binding to cardiolipin, SS-31 helps to stabilize the inner mitochondrial membrane, protect it from oxidative damage, and preserve the integrity of the electron transport chain. While its plasma half-life is relatively brief,
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — NAD+ (Nicotinamide Adenine Dinucleotide) and SS-31 (Elamipretide) are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between NAD+ (Nicotinamide Adenine Dinucleotide) and SS-31 (Elamipretide)?
Both are classed as Longevity peptides, so they get compared constantly and are often researched for overlapping reasons.
Can you log NAD+ (Nicotinamide Adenine Dinucleotide) and SS-31 (Elamipretide) in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, NAD+ (Nicotinamide Adenine Dinucleotide) or SS-31 (Elamipretide)?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
