What GHK-Cu, TB-500 and NAD+ cost per vial from Australian research suppliers in 2026 — three different compound classes grouped by price-shopping behaviour, not biology.
Written by the Peptide Labs Research Team
This is part of our research peptide price breakdown series — start there for how pricing works across the whole catalogue.
GHK-Cu, TB-500 and NAD+ are mechanistically unrelated — a copper-binding tripeptide, a synthetic peptide fragment, and a coenzyme respectively. They're grouped on this page because they get price-shopped together in practice (all mid-catalogue price points, and frequently bought alongside the BPC-157 + TB-500 blend), not because they belong to the same research category. Treat this as a price round-up, not a claim that the three are biologically comparable.

TB-500 is stocked both on its own and combined with BPC-157 in a blend vial. The blend costs more than a solo TB-500 vial (you're getting two compounds) but less than buying both compounds separately — the same one-vialling, one-QC-pass economics covered on the BPC-157 price page. Which option makes sense depends on your research design, not on price alone.
NAD+ is a larger, more structurally complex molecule than either GHK-Cu or TB-500, which — following the same synthesis-cost logic used throughout this price series — typically puts it in a different price band. This is a factual note about molecular size and manufacturing cost, not a comparison of research usefulness.
Why are GHK-Cu, TB-500 and NAD+ on the same price page if they're unrelated compounds?
Purely for price-shopping convenience — they sit in a similar price bracket and are often compared or bought together. It's not a claim that they share a mechanism.
Is the BPC-157 + TB-500 blend better value than solo TB-500?
It's typically cheaper than buying both compounds separately if your research design calls for both — but it isn't a substitute for solo TB-500 if your design only calls for one compound. Check live pricing on both listings.
Why does NAD+ cost more than GHK-Cu per vial?
NAD+ is a larger, more complex molecule, which generally means more synthesis and purification cost per batch — a manufacturing factor, not a research-value comparison.
