Is injected NAD+ better than oral NAD+?

Subcutaneous delivery avoids first-pass metabolism in the gut and liver, so more of the dose reaches circulation than from an oral precursor. That bioavailability difference is the main argument for the injectable form.

Most locally available NAD+ cartridges sit at 450–500 mg. We specify 600 mg per cartridge so a protocol can be run without stacking cartridges to reach a research-typical dose.

Do I need a pen for this?

Yes. It's supplied as a standard 3 ml cartridge, which loads into the reusable click-pen in the Starter Kit or a single-use Disposable Pen. Nothing to reconstitute or measure — you load the cartridge, click the dose, attach a needle.

How fast is delivery in South Africa?

We ship nationwide with The Courier Guy, typically 1–3 working days to major centres and 2–4 to outlying areas. Cold-chain items go out in insulated packaging with tracking on every parcel. We ship within South Africa only.

No. Everything in the range is supplied as a research compound, not a registered medicine, and nothing here is a prescription, diagnosis or treatment recommendation. Products are not made in South Africa — they are imported and distributed locally by SummerPeptides.

How NAD+ works

NAD+ is a coenzyme present in every cell, sitting at the centre of how mitochondria turn fuel into ATP. It is also the substrate that sirtuins and PARP enzymes consume when they carry out DNA repair — which is why it appears in almost every longevity conversation.

Cellular NAD+ declines measurably with age. Oral precursors are the common route to raising it, but absorption is the limiting factor; subcutaneous delivery bypasses first-pass metabolism and reaches circulation more completely.

This cartridge is 600 mg, meaningfully above the 450–500 mg that has become the local norm. Dosing is per protocol rather than fixed weekly, and flushing or warmth during administration is a commonly reported, dose-related effect.
