What is P7C3?
Plain language first. The technical label stays, but it never stands alone.Overview
A small molecule that keeps young brain cells alive in animals by boosting NAD. No human trial has ever been run.
P7C3 is an aminopropyl carbazole that binds and activates NAMPT, the rate-limiting enzyme in the NAD salvage pathway, producing proneurogenic and neuroprotective effects across rodent models of Parkinson's, ALS, traumatic brain injury, stroke and depression.
What it's used for
Sold for brain protection and cognition. Everything published is in cells, rodents and one monkey study.
How does P7C3 work?
What it does in the body, and where.P7C3 was named after where it sat on a screening plate, which tells you how it was found.
- 01A screen in live miceResearchers looked for anything that increased the survival of newborn hippocampal neurons. The third compound in the seventh pool worked.
- 02The target turned out to be NAMPTThe enzyme that limits how fast cells make NAD, which is why the effect looks like protection rather than growth.
- 03It stopped at monkeysA 38-week study in rhesus monkeys extended the rodent findings. No human trial has followed.

What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.

How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized P7C3 keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
