BTLabs: tests, prices and how to send a sample

BTLabs is a US testing lab whose site lists purity, potency and identity testing by HPLC and FT-IR, plus endotoxin and sterility. It publishes no prices, turnaround or street address, and its price list comes through a request form. Its standard identity method is FT-IR rather than mass spectrometry, so ask for MS if you need to tell similar peptides apart.

What its reports in our archive show

We hold 83 reports that name BTLabs directly, dated Oct 6, 2025 to Sep 16, 2026, with 35 in the last 90 days.

Share of these reports that print each result. These are shares of published reports, not the lab's menu. A report can name the compound it found without printing a separate identity result.

Amount: 92.8%
Separate identity result: 73.5%
Mass-spec identity result: 0.0%
Endotoxin: 81.9%
Sterility or microbial: 79.5%
Heavy metals: 0.0%
Solvents: 0.0%
TFA: 0.0%

We hold report text or structured results for 98.8% of these reports.

We do not compare its amounts with other labs yet: fewer than 30 batches in our archive were tested by this lab and by another lab named on the report. Why labs report different amounts.

Sellers choose which reports to publish, and we hold only what reached our archive. These numbers describe our archive, not each lab's total work. Reports sent through Finnrick are counted on the Finnrick page, not under the lab that ran them. Archive as of Oct 10, 2026.

Pro members can open each report in our library. It does not filter by lab yet. See Pro plans.

Known issues

BTLabs describes its identity test as HPLC plus FT-IR, not mass spectrometry. FT-IR is less specific for telling similar peptides apart, so ask for MS identity if you need it.
