Nothing goes on sale
until its certificate is back.
Every compound we sell has its own independent certificate of analysis published on this site before it can be ordered. A batch whose certificate is still pending is listed, marked “awaiting our COA”, and cannot be purchased. As of today that is nine compounds in the range. When a certificate arrives we publish it, and the batch goes on sale the same day.
Where to find the certificates
All of them are at /coas, each with the laboratory’s certificate number, the batch it covers, the purity reported and the report date. How to read one is at /coas/how-to-verify.
Who we are
Southern Pacific Labs is a business name of Southern Labs AU Pty Ltd, ABN 47 696 872 698, based in Sydney, Australia. Female founded. We stock locally and dispatch from Sydney.
A note from the founder
I started this because I wanted to buy from somewhere that showed its work. So we publish every certificate before anything goes on sale, and we hold the ones that aren’t back yet. It costs us time on every batch. I think it’s the only honest way to do this.
Research use only. Nothing on this page is medical advice or a therapeutic claim.
Built differently. On purpose.
Most peptide research suppliers are built around a catalogue. You browse. You order. You wait. That’s the transaction.
We’re trying to build something different.
We’re female-founded. We’re based in Sydney. And we believe the way you’re treated should match what you’re paying for.
The model in our heads isn’t another peptide company. It’s the kind of place where someone holds the door for you. Where the person at the counter knows your name by your second visit. Where the bags get carried to the car not because they have to, but because that’s how the company has always done things. There’s a name for that — old-school service — and somewhere along the way most of the internet forgot what it looks like.
A focused range of research peptides we can stand behind. Sourced from manufacturers we know by name and tested at source, then verified again through our own independent third-party lab before anything goes on sale. Handled with attention, not automation.
Care isn’t a statement. It’s a system.
Sourced and verified at origin. We work with two established manufacturers we’ve built ongoing relationships with. Manufacturer-commissioned laboratory testing confirms purity, identity, and quality before anything leaves the source. Third-party verification at the manufacturer level, at the start of the chain.
A second, independent layer. Beyond the manufacturer’s testing, we run our own third-party verification through a US-based analytical laboratory — Ultra High Performance Liquid Chromatography with Mass Spectrometry, from the same facility relied on by some of the leading peptide and bioregulator suppliers in America. We publish these COAs as each batch is verified and keep them current — so the documentation behind your order stays live, not static.
Australian lab partnership in progress. We’re actively working toward partnering with an Australian laboratory for ongoing domestic verification. This page will be updated when it’s confirmed.
Meeting our manufacturers. Later this year we’re sitting down with our manufacturers in person. We’re spending time onsite in their facilities, where their teams walk us through their processes first-hand — how quality is controlled, how the work is done, and the standards behind it.
Our purity guarantee.
If any product purchased from Southern Pacific Labs fails a purity test at a licensed testing facility, by the method its certificate uses (UHPLC–MS), we will refund the full order cost, shipping fees, and the cost of the test — upon verification.
We don’t bury this in fine print. It’s the offer. If the product isn’t what we say it is, you shouldn’t pay for it.
We tell you when this page changes. No quiet edits. If a stage completes, you’ll know.
Real people. When you need us.
Questions before you order. Questions after. Questions about a peptide, a guide, a delivery, the fine print on a COA. Either way — we’re here every day, with real hours, real responses, and real people. Not a ticket bot. Not a 48-hour email queue.
All times AEST
That’s the whole point. We didn’t build Southern Pacific Labs to be the biggest. We built it to be the one you stay with.
