“Best” is doing a lot of work in a phrase like this. There is no single best research peptide — there is the compound that suits the question you are asking, supplied by someone who can show you what is in the vial. This page covers both: what we currently hold, how the compounds differ, and what actually separates one Australian supplier from another.
Everything below is supplied strictly as reference material for laboratory research, not for human or animal use.
Nine products, all dispatched from Australian stock. Prices and live stock are on each product page rather than here, so this page cannot go stale on you.
If a compound is not on that list, we do not sell it. Suppliers who list everything and hold nothing are a pattern worth recognising — see how to spot a peptide scam.
BPC-157 and TB-500 are the two most-requested compounds in this area, and the literature usually treats them as complementary rather than interchangeable: different mechanisms, frequently studied together. If you are running a repair protocol, BPC-157 with TB-500 is the pairing to read up on first. GLOW and KLOW are pre-blended versions for researchers who would otherwise be reconstituting three or four vials separately.
R3TA is our retatrutide reference material, and it is the compound generating most of the current interest — the phase 3 programme has reported results that put it ahead of the earlier GLP-1 agonists on weight endpoints. MOTS-C sits in a different place: a mitochondrial-derived peptide studied for its effects on metabolic signalling rather than appetite.
GHK-Cu is the compound with the deepest published record here, and it appears in GLOW alongside the two repair peptides. This is the area where purity matters most obviously — a copper peptide that is not what the label says will not behave the way the literature describes.
Almost every Australian peptide site claims high purity, fast shipping and quality assurance. The claims are free to make. Three things are not.
We publish certificates in a certificate of analysis library, organised by product, and the lot number on the certificate matches the vial you receive. Two separate analyses are run on each lot: mass spectrometry to confirm identity against the expected molecular weight, and HPLC to measure purity against a specification of 99% or greater. A supplier who offers “documentation on request” and then sends the same PDF for every product is not doing this. If you have not read one closely before, start with how to read a certificate of analysis.
We hold stock in Australia and dispatch domestically, which removes the customs risk and the multi-week wait that comes with international orders. It does not make dispatch instant, and we would rather say so: orders are processed within 1–2 business days of payment clearing, and payment by bank transfer can add 1–3 business days before that clock starts. Transit is typically 2–4 business days to the metro capitals and longer to regional and remote areas. The shipping policy has the full detail.
The least glamorous signal and one of the most reliable. Send a supplier a specific question — which lot is currently shipping, what the last HPLC result was — before you order anything. The answer, or the absence of one, tells you most of what you need to know.
For repair research, BPC-157 is the usual entry point — the largest published base and the most straightforward handling. For metabolic work, R3TA. Neither is a recommendation about outcomes, only about where the literature is deepest.
No. Our catalogue is the nine products listed above, and R3TA is the only compound we hold in that class. We would rather tell you that than list compounds we cannot supply.
For anything crossing a border it is the single biggest variable. International shipments can sit in customs for weeks, arrive degraded, or not arrive at all, and a refund does not give you back the time. Domestic transit is shorter, tracked, and predictable.
It is the HPLC figure: the peptide as a percentage of everything in the vial. The remainder is typically residual solvent, water, counter-ions from synthesis and truncated sequences left over from manufacturing. The number is only meaningful when it comes with the method and the batch it was measured on.
Pick the compound that matches your research question, then judge the supplier on evidence rather than adjectives: certificates published per batch with named methods, stock held in Australia, honest timeframes, and someone who answers your questions. Our full catalogue is here, and every product page links through to the certificates.
New batch COAs and restock alerts, sent when they happen.
