How is this different from the GHK-Cu serum?

Same headline molecule, different delivery. The serum works at the skin surface; the Glow cartridge delivers GHK-Cu subcutaneously alongside BPC-157 and TB-500, so the research interest extends to systemic repair rather than topical appearance alone.

Can I use the serum and the stack together?

They're commonly used alongside each other — the topical for surface-level routine, the cartridge for the systemic protocol.

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 Glow works

The signature stack: GHK-Cu, BPC-157 and TB-500 in one cartridge. GHK-Cu is a copper-binding tripeptide found naturally in human plasma, with declining levels through adulthood and an unusually deep body of published research on collagen synthesis, skin remodelling and antioxidant activity.

Delivered systemically rather than topically, GHK-Cu is studied for regenerative effect beyond the skin surface — which is the reason it is stacked here with two repair peptides rather than sold as a serum alone.

BPC-157 contributes localised tissue repair and anti-inflammatory action; TB-500 contributes full-body recovery and remodelling. The result is the bridge between the skincare range and the therapy range.
