Quality and Testing
Every AminoBlend vial can be traced to its production lot, and every lot is tested by an independent laboratory before release, so when you buy research peptides online from us the evidence is there to read first.
Lot-Numbered Vials
Each vial label shows the product, strength, lot number and expiry date. The lot number is the key to the vial's history: it links to the production batch, the test results and the storage conditions for that batch.
Independent Testing for Every Batch
Before a lot is released for sale, samples go to an outside laboratory that confirms identity by mass spectrometry and measures purity by HPLC. Both results are written onto the certificate issued for that lot, and a lot that does not meet its specification is not sold.
A Certificate of Analysis for Every Lot
You can look up the COA for any lot on our COA lookup page before you order or once the vial is in your lab. If you are new to reading COAs, the guide to making sense of a certificate of analysis explains each result, and the lab tested peptides page sets out what this testing proves and where it stops.
Vials and Packaging
| Component | Specification |
|---|---|
| Peptide vials | 3 mL clear glass vial with rubber stopper and flip-off cap (10 mL for NAD+ and glutathione) |
| Form | Lyophilized (freeze-dried) powder |
| Labelling | Product, strength, lot number, expiry and research-use statement |
| Outer packaging | Carton to protect from light |
How Stock Is Stored
Lyophilized stock is held cold and away from light until it is packed. See our storage guide for how to keep vials once they are in your lab.

Every product in the range goes through the same testing, so you can buy with the certificate open beside the listing. Common starting points are BPC-157 for repair research, GHK-Cu for copper peptide work, the CJC-1295 and ipamorelin blend for growth hormone studies and retatrutide for metabolic models. Shop the full range and order online from Australian stock, or request a bulk quote through the wholesale page if your lab buys in volume.
Shop Lab-Tested Peptides Online
Testing only matters if it changes what you buy. Before you order, open the certificate for the exact lot in the COA library, then buy online with that report in hand. Every product in the peptide shop follows the same process, from BPC-157 to the blends, and our lab-tested peptides page explains how to compare suppliers on testing rather than price. No need to find a supplier near me: the evidence is published online for every lot.
Quality and Testing Explained
What Does HPLC Measure in a Peptide Sample?
High-performance liquid chromatography dissolves a small sample and pushes it through a packed column, where each component exits at its own retention time. A UV detector logs each component it sees, and purity is reported as the target compound's share of the total detected area, so a 99.1% result means almost all the UV-absorbing material is the target sequence.
What Does Mass Spectrometry Confirm That HPLC Cannot?
HPLC says how clean a sample is, not what the main compound actually is. Mass spectrometry weighs the molecules and reports an observed mass, which the lab compares with the expected molecular weight of the named peptide. A close match confirms identity; a wrong mass means the vial holds something else, however tidy its HPLC trace looks.
What Is a Lot Number and Why Is It on Every Vial?
A lot is one production batch made and filled together. Its lot number is printed on each vial label beside the product, strength and expiry date, and the same number appears on the certificate of analysis for that batch. That number is the only reliable link between the glass in your hand and a test result.
How Do You Match an AminoBlend Vial to Its Certificate?
- Read the lot number from the vial label, character by character.
- Search for it in the AminoBlend COA library.
- Confirm the compound name and strength on the report agree with the label.
- Check that the mass spectrometry result confirms identity, then note the HPLC purity figure.
What Should the Powder Look Like in a Tested Vial?
Most of our peptides come as a white or off-white lyophilised cake in a 3 mL clear glass vial, while the larger NAD+ and glutathione fills use 10 mL vials. GHK-Cu is the visible exception: its bound copper makes the powder blue, and its certificate records that appearance.
Where Are the Report's Finer Details Explained?
Chromatograms, retention times and specification limits are covered line by line in our guide to interpreting a peptide certificate of analysis. A lot that fails its specification at the independent laboratory is never released, so every report you can look up belongs to stock that passed.
