Peptides

TB4/TB-500/TB4(17-23) analysis

ID, amount and purity analysis of TB4,TB-500 and TB4(17-23).

The test will determine whether the whole 43 amino acid chain of TB4 is present in the sample, or just a fragment. Then it will accurately measure it’s amount and peptide purity.

This is distinguished on the report in the following way:

TB-500 (TB-4) – entire peptide was identified.

TB-500 – only a fragment was found, comment section of the report will include information on which exactly.

TB-500 889 (Da) – fragment 17-23 was identified.

You can find the test details in the parameters section below.

Additional Services

TFA analysis
(+$290.00)

Detection and measurement of TFA (Trifluoroacetic acid) in the sample. Results are in mg per vial.

Raw Data
(+$25.00)

All the raw data you can possibly get. From the main test as well as from all additional services when appliable.

Fentanyl presence analysis
(+$75.00)

Checks for fentanyl in the sample.

Alternative results format: m/m purity
(+$0.00)

Alternative results format will give you m/m purity. Peptide purity is included for peptides. This result format is only for raw API powders. The rule of thumb is if you’re unsure whether you need this, then you don’t and you can leave this checkbox unchecked. Leaving the checkbox unchecked will give you mg/vial for lyophilizated peptides, or mg/pill for oral samples.

Variance Testing
(+$75.00)

You have reached the limit for additional reports. If you want to order more please let us know.

Testing of multiple pieces of the sample for a premium price to check the variance inside a single batch. Please mind that all pieces have to be from the same batch of the same product.

pH Measurement
(+$35.00)

Measures the pH of the sample.

Endotoxin Analysis
(+$180.00)

Measurement of LPS presence in the sample. We offer this analysis only for finished products. Please do not order for raw powders. Please note our standard endotoxin test is accurate for values up to 10 EU/vial. Values above 10 EU/vial are estimated. For a perfectly accurate result of a sample with more than 10 EU/vial a new test is necessary, for a discounted price of 120 USD, with a different vial and dilution. Therefore, we also recommend sending two vials for the testing. Alternatively, if you already expect the values to be above 10EU/vial, let us know via email. We will run only one test for 180 USD calibrated for such values straight away.

CHNS Mass Report
(+$145.00)

CHNS provides accurate measurement of nitrogen and sulphur content, making it the golden standard in net peptide content (NPC) determination.

Additional report
(+$35.00)

You have reached the limit for additional reports. If you want to order more please let us know.

Additional report with a separate client name.

LCMS Screening For Peptide Contamination
(+$205.00)

LCMS testing can detect contamination of peptide products with other peptides and degraded peptide. Detection is limited to peptides on our price list. You can ask our customer support for the full list, Test gives only identification. Measurement of concentration can be offered for an additional price once contamination is detected.

Sterility Testing
(+$290.00)

TAMC/TYMC: TAMC and TYMC tests check the presence of bacteria and molds in the product. Testing requires unopened additional pieces of sample to be sent for analysis. Average turnaround of this test is 14 days.

Heavy Metals Analysis
(+$105.00)

Detects presence of As, Cd, Pb, Hg. For other metals please ask our customer support.

Can I get a report without sending a sample?

No.

Can we test as a group?

Yes, you can! However, e-shop does not support group orders and payments. Please write us your order via the contact form and choose “Group testing” as a subject. Our customer care team will get back to you and will guide you through the group ordering process.

Can I expedite my testing?

Yes, you can! Please write us a number of the order you want to rush and choose “Expedited testing” as subject. You can either rush the whole order, or specific tests. Price is always 100% surcharge of the value of the expedited tests. Please note some of the additional tests cannot be rushed. We recommend writing before the sample arrives at our lab, to make sure we can still put them in front of the queue.

What are additional services?

Additional services present you with enhanced harm reduction tests and test specific options for the analysis of your sample. Please mind in case you select any additional service for the sample, our e-shop needs to put them in the cart together with the said sample. When you have more samples of the same test with additional services, you need to add the samples to your cart one by one. For example: you want to test Tirzepatide 15 mg with sterility testing and Tirzepatide 30 mg with heavy metals testing, you need to add the sample one by one.

Do I need to send more pieces of sample for additional services?

It’s recommended for some of them, sending less may impact the results. Let’s tackle it one by one: GCMS and LCMS - no additional piece of sample is necessary; Heavy metals analysis - 1 tab/caps, 1 ml of solution, 200 mg raw powder, 1 hole vial of lyophilizate; Sterility testing - 2x whole unopened peptide vial, 2x unopened 1ml ampoule,1x unopened 10ml vial, unopened pieces are needed as to prevent contamination before testing; Endotoxin analysis - 1 vial (2 recommended) or 1 ml (2ml recommended), CHNS mass report - no additional piece of sample is necessary; Iodide/Chloride analysis - 1 tablet/capsule, PH measurement - no additional piece of sample is necessary; Fentanyl presence analysis - no additional piece of sample is necessary, TFA analysis - no additional piece of sample is necessary.
