Blackline Scientific sits 9% below market the tracked market median on matched peptide/size rows. The catalog in this index is smaller than Tetrava Labs's. On COA coverage, Blackline Scientific rates none found and Tetrava Labs rates none found. Based on the certificates our crawler found; vendors may publish more than we index.
The honest comparison unit is price per mg on matched peptide/size rows. COA coverage is presence of a current indexed document, not purity-as-quality. See the Evidence Atlas and how to read a COA.
Evidence boundary: Listed prices, stock signals, and indexed COA documents are observations. They do not establish legitimacy, authenticity, safety, sterility, chain of custody, product quality, fulfillment, or suitability. No vendor is endorsed.

Questions about Blackline Scientific
Is Blackline Scientific legit?
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for Blackline Scientific. We found no certificates for the in-stock products we track. Based on the certificates our crawler found; vendors may publish more than we index. We have been recording their prices since August 18, 2026. Read each certificate yourself, check that its lot and compound match what you are buying, and treat anything we have not recorded as unknown rather than as an answer.
Does Blackline Scientific publish COAs?
We found no certificates for the in-stock products we track. Based on the certificates our crawler found; vendors may publish more than we index. We have not recorded a testing or COA page on their site. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
What payment methods does Blackline Scientific accept?
At the time we recorded it, Blackline Scientific listed PayPal, Venmo, Cash App, cryptocurrency and Zelle. Peptide storefronts change processors often, so the options at checkout may differ from what we hold.
Does Blackline Scientific have a coupon or discount code?
We have none on record for Blackline Scientific. When a code we can verify appears, it shows on this page and the prices here are adjusted for it; until then, every figure on this page is the list price.
How do Blackline Scientific prices compare to other vendors?
Across 22 graded products, Blackline Scientific's median price per mg sits 8.7% below the median for the same peptide at the same vial size. We track 30 products from them in total. Price per mg is the comparison unit: a cheaper vial holding less is not a cheaper product.

No current record names a lab.
No current certificates are on file for the tracked market listings on this page.
A record appears on file after our pipeline identifies the document as a certificate of analysis and matches its printed compound to a catalog peptide. The record cannot prove authenticity, chain of custody, sterility, product safety, or suitability for use.
These are counts of documents in our index, and a coverage rating of what our crawler found. They do not grade vendor quality, legitimacy, or safety. Printed fields can contain transcription errors. “Older record” means the reported test date is more than 18 months old.
