How pure is the sample?
HPLC separates components in a sample. Purity analysis compares the target peak with the other peaks detected by the method.
Independent peptide testing
Independent peptide testing, with HPLC purity analysis and endotoxin screening planned for launch. Tell us what matters to you, and help shape what comes next.

Why we started Amberline
People close to us were buying and using peptides from overseas suppliers we had concerns about. We wanted to know whether what they were getting matched what they thought they had bought.
We started Amberline to get independent answers. That concern for the people we care about is what’s driving us to build this lab.

Launch services
HPLC purity testing and bacterial endotoxin screening will be our focus at launch. Each result will identify the sample, the test performed, and the method used.
HPLC separates components in a sample. Purity analysis compares the target peak with the other peaks detected by the method.
A separate assay screens for bacterial endotoxins. The result is reported in the context of the method and its detection limit.
Identity and measured amount will be reported where supported by the selected test and compound-specific method. Available panels, accepted compounds, sample requirements, and pricing will be published when intake opens.
See the report formatReading the numbers
A high purity percentage describes the detected composition. It does not, by itself, tell you the number of milligrams in the vial.
Quantitative testing answers that separate question by comparing a measured amount with the label claim.
Hypothetical example to explain the difference. Not a result from our lab.
Tell us what you need
We know why we wanted this lab. Now we want to understand what you need from it.
Single-vial testing? Faster results? Screening you can’t easily find elsewhere? Your answers will help us decide what to prioritize.
Choose any interests that apply, or leave a note in your own words. We’ll send one email when sample intake opens.
Your answers will help us prioritize service options, pricing, turnaround, and future additions to the launch offering.
Sample report
The result should be easy to find, and the method behind it should be easy to check.
This illustrative format shows identity, purity, and quantitative results. Your report will reflect the tests included in your selected panel.
A result applies to the submitted sample. It does not certify a supplier or an entire batch. Purity and endotoxin results alone do not establish that a peptide is safe to use or appropriate for a person.
Certificate of analysis
Label claim: 10.0 mg
Example values only. Not an issued certificate or evidence of sample safety. BPC-157 is shown for illustration and is not a confirmed accepted compound.
Testing, sample requirements, and launch updates.
Not yet. Leave your email in the form above and we’ll notify you when sample intake opens, with the test panels, pricing, and submission instructions.
Pricing is not finalized. We’re considering single-vial testing and other options. Tell us what would be useful to you in the form above. Minimum quantities and turnaround times will be published before intake opens.
We’ll publish the accepted compound list and sample requirements when intake opens. The compound shown in the illustrative report is an example, not a confirmation that it will be accepted.
Yes. Bacterial endotoxin screening is part of our planned launch offering, alongside HPLC purity testing. Endotoxin screening is a separate assay and does not replace sterility, heavy-metal, or broader microbial testing.
No. A lab result answers the specific questions covered by the tests performed. It does not establish safety for human use, determine an appropriate dose, or replace medical advice. Endotoxin screening is also different from sterility testing.

A searchable results library is under consideration. No public library is available today. The planned service uses specimen identifiers; it does not test human specimens or collect personal health information.
