The compound

NAD+ with B12, plainly explained.

NAD+ (β-Nicotinamide Adenine Dinucleotide) is a cellular cofactor central to mitochondrial energy metabolism and sirtuin-pathway biology. It is one of the most studied molecules in longevity and cellular-energetics literature.

The pen you're looking at contains 500 mg of NAD+ solution including 4000 mcg of Vitamin B12, pre-mixed in a stabilised aqueous matrix. Co-formulating B12 in the same pen removes the need to stack a second injection and standardises the dose batch to batch.

Every pen is filled, sealed and serialised in a UK facility, then released against independent HPLC and mass-spec assays. The pen ships in an insulated cold-chain pack with a temperature strip you can verify before it ever touches a freezer.

"Every batch HPLC-verified in a UK lab. Shipped cold. No reconstitution required."

How it works

From cold-chain box to bench, in three steps.

  1. 01

    Receive cold

    Insulated pack, temperature strip on the carton, tracked UK courier.

  2. 02

    Refrigerate

    Store the sealed pen at 2–8 °C. Stable across the full usage window.

  3. 03

    Dial and dispense

    Attach a sterile needle, dial the dose, hold 5 seconds. Same concentration, every session.

Why pre-mixed

Reconstituted powder vs. PeptOnline pen.

Traditional lyophilised NAD+ vial

  • Source lyophilised NAD+ vial + separate bacteriostatic water
  • Calculate concentration, reconstitute, swirl (no shaking)
  • Draw with insulin syringe — hope the maths checks out
  • Recap, refrigerate, hope stability holds across the study

PeptOnline pre-mixed pen

  • Unbox cold-chain pack, verify temperature strip
  • Refrigerate the sealed pen at 2–8 °C
  • Dial the dose — no maths, no reconstitution, no B12 added separately
  • Same pen, same concentration, every time

Cold-chain held up perfectly

Pen arrived chilled with the temperature strip in spec. Our in-house HPLC matched the certificate within tolerance.

B12 co-formulation is the upgrade

Standardising NAD+ and B12 in the same pen removed two sources of variance from our protocol overnight.

Reliable UK source for NAD+

Hard to find a UK lab actually willing to attach a COA. The pen format makes documenting sessions trivial.

Dial graduation is excellent

Fine-graduation dial means we can run dose-response work straight off the pen. Cold-pack courier turned up next day.

No reconstitution = no errors

NAD+ powder is notoriously fiddly to reconstitute. The pre-mixed pen has dropped our intra-session CV sharply.

Tracked dispatch is a relief

Tracking pinged the whole way. Insulated box, cold packs solid on arrival. Quality matches the spec sheet exactly.
