Neurolevel is a research peptide catalog with a single rule: nothing enters the index without a published paper trail. We do not stock compounds we cannot cite.
The brand exists because the peptide market is full of black boxes — mystery sources, vague COAs, and marketing dressed as science. We do not run that playbook. We run a catalog with citations attached.
Sourcing · Assay · Shipping
Source
Compounds are sourced from registered synthesis facilities with documented batch provenance. We do not work with consolidators, brokers, or unverified upstream chains.
Assay
Every batch ships with an independent certificate of analysis from a third-party accredited lab. Minimum 98.0% assayed purity. Below that, the batch is rejected before it enters the index.
Ship
Lyophilized compounds ship domestically (US) as standard, with international service to select countries. Cold-chain integrity is verified at handoff. Standard domestic transit is 1 to 3 business days from order confirmation.
The Operation
Neurolevel is a research peptide catalog focused on research-grade neuropeptides. A compound enters the Index only when it carries a published paper trail; if the citation record is thin, it stays out.
Quality control holds a minimum 98.0% assayed purity release specification, verified by a third-party accredited lab. Batches below specification are rejected before they enter the Index.
Neurolevel operates as a Wyoming, United States limited liability company. Research and sourcing questions go to contact@neurolvl.com. For research purposes only. Not for human consumption.
QC Process
High-performance liquid chromatography (HPLC) and mass spectrometry (MS) are run on every batch. Sample chromatograms are retained for 24 months.
