CURATION
Limited on purpose.
Most peptide vendors carry eighty SKUs. We carry twelve. Every compound in the line is third-party tested at the source lab. Most don't pass. The line is small because the bar is high.

BEHIND THE LINE
No fluff. Just answers.
Most peptide vendors hide their suppliers, dodge questions, and skip testing. We do the opposite. Every product, every answer, on this page.
ABOUT NLL
Built by researchers, for researchers.
NLL was founded by researchers tired of opaque sourcing. We carry twelve research compounds because that is what passes our lab. Anything below 99% purity is discarded.
Independent US labs run HPLC and LC-MS at the source on every product in the line. Sterility and endotoxin verified. Reports public. Vials shipped fast in plain packaging to US researchers only.
HOW WE TEST
Four checks per batch. No shortcuts.
-
01
HPLC purity
High-performance liquid chromatography. Confirms peptide identity and purity ≥99%.
-
02
LC-MS verification
Mass spectrometry confirms exact molecular weight matches the target peptide.
-
03
Sterility test
Lyophilized powder cultured. Negative for bacterial and fungal growth.
-
04
Endotoxin assay
Limulus amebocyte lysate (LAL) test. < 0.5 EU/mg.
FAQ
Common questions.
Are these for human use?+
No. All NLL products are research compounds intended for in vitro laboratory use only. Not for human consumption. Not evaluated by the FDA. Not intended to diagnose, treat, cure, or prevent any condition.
How fast does shipping ship?+
Most orders ship within 1 to 2 business days of payment. USPS Priority Mail with 2-day delivery. US addresses only. Discreet plain packaging.
What payment methods?+
Venmo to @NLL01 or Zelle for instant orders.
Do I need bacteriostatic water?+
For research reconstitution, yes. We sell USP-grade bacteriostatic water. Reconstitution and storage parameters should follow the recipient laboratory's standard protocols for peptide handling.
Can I return product?+
Unopened vials within 14 days of delivery. We refund 100% if the COA does not match what we shipped, full stop.
How do I store vials?+
Lyophilized peptides: room temp until opened, then 2-8 °C. Reconstituted: refrigerate, use within 28 days. BAC water: room temp.
WHAT MAKES US DIFFERENT
What others cut, we double down on.
Every research peptide vendor claims purity. We chose four places to spend extra money instead of cutting corners. The four that actually matter for what lands at your door.
01 · LABELS
QR ON EVERY VIALScannable, traceable labels.
Most vendors hand you a vial with a tiny sticker and a Sharpie note. Every NLL label is printed with the product, dose, lot, expiry, and a QR code that resolves to the COA for that batch on this site. Receipts on every vial.
02 · GRADED
FINRICK A · 9.1 AVGA-graded by an independent lab.
Finrick independently grades research peptide vendors. We average a 9.1 of 10 across 20 graded samples, the highest tier their scale offers. Every score is public on their site, with the lot, date, and method spelled out. No marketing math.
03 · TESTING
HPLC + LC-MSFinrick tests every product in the line, not just one.
Finrick runs full HPLC and LC-MS identity and purity panels on every compound in our line at the source, plus sterility and endotoxin where applicable. Most vendors test one hero SKU and recycle that COA for years. We publish the source-lab report for every product we sell.
04 · STANDARD
<99% = DISCARDAnything under 99% never ships.
If a compound comes back below 99% purity at the source lab, it never enters the line. We don't sell it discounted, we don't blend it. A COA ships with every order and every product's source-lab report lives in the public library on the lab reports page. Receipts on every vial.
