Every batch is third-party verified for purity and independently tested using HPLC and LC-MS to confirm molecular integrity. Sterility, endotoxin, and contaminant testing ensure consistent, research-grade quality with no exceptions.
Testing protocol
What independent testing covers
The checks an independent laboratory can run on a lot. The certificate for your lot lists exactly which tests were performed and what they found.
Purity measured, not asserted.
Reverse-phase HPLC separates the target compound from everything else in the vial and integrates the result. The figure on the certificate is the area under the product peak as a share of total area — read off a trace like the example below. The figure that applies to your vial is the one on its own certificate.
- 214 nm detection
- C18 column
- Area normalisation
Target compound
- Retention
- 6.2 min
- Area
- 99.42%
The main peak. Purity is its share of the total integrated area, and its identity is confirmed by mass spectrometry at the same retention time — area alone would only tell you something is there, not what.

Frequently asked questions
What quality testing do you provide?
Every batch ships with a Certificate of Analysis from an independent laboratory. Testing is performed by HPLC with UV detection coupled to mass spectrometry, covering identity, purity, and appearance.
How do I read a Certificate of Analysis?
The COA lists the compound identity, the measured purity percentage, the analytical method used, and the batch number. Match the batch number on your vial to the batch number on the certificate — they should be identical.
What purity should I expect?
Purity is measured lot by lot. The measured figure for the specific lot you receive is printed on that lot's certificate of analysis, which ships with the order.
How should I store unopened peptides?
Lyophilised peptides are stable at 2–8°C in a sealed container away from light. For storage beyond a few months, -20°C is preferred. Avoid repeated freeze-thaw cycles.
How long do reconstituted peptides last?
Once reconstituted, stability depends on the compound and the diluent. As a general guide, refrigerated solutions in bacteriostatic water remain usable for research purposes for several weeks. Consult the compound's technical sheet.
What are your shipping times?
Orders placed before 12:00 PM on a business day ship the same day. Standard domestic delivery is 2–5 business days and is free on orders over $300.
Do you ship internationally?
Not at present. Harbourpep supplies from Australia to delivery addresses within Australia only.
Are research peptides legal to purchase?
The compounds we sell are supplied strictly for in vitro laboratory research. They are not medicines and are not approved for human or veterinary use. Confirm the rules that apply in your jurisdiction before ordering.
Why do products say "not for human consumption"?
Because that is exactly what they are. These materials are manufactured and sold as research reagents. They have not been through the testing or approval required of a therapeutic product, and using them as one is unsafe.
What is your return policy?
Report anything damaged, short or incorrect within 7 days of delivery and we will replace or refund it. We do not accept change-of-mind returns once an order has been dispatched, because we cannot verify how a vial has been stored once it leaves our custody. You can cancel for any reason, free, at any point before we confirm dispatch.
How can I contact support?
Email our team and you will hear back within one business day. Support is staffed weekdays, 9:00am to 5:00pm.
What if my order doesn't arrive?
Every shipment is tracked. If tracking has not updated for five business days, contact us with your order number and we will open an investigation with the carrier and reship or refund.
