Level Up Peptides (level-up-peptides.com) is a US-based research-compound supplier. One thing is worth knowing before you click through: its storefront is register-to-browse. Every catalog page returns a “Login Required” screen asking you to log in or create an account, and no products or prices render until you do. Registration is free, and it gates browsing rather than purchasing alone.
That account wall is the reason this page carries no compound list. Prof. Peptide lists a vendor’s catalog by research area where the catalog is publicly readable; here it is not, and a list assembled anyway would describe shelves a reader cannot see for themselves.
What earns Level Up a page is its testing record, which is the deepest of any vendor on this site. Its compounds are tested by Freedom Diagnostics. The certificate we reviewed — lot LU-LC10.A, reported August 24, 2026 — goes well past the purity-and-identity core that most research-market certificates stop at. It reports purity at 99.85% by HPLC-UV, identity by LC-MS, and measured net peptide content; then it adds three panels almost nobody else in this market runs.
Bacterial endotoxin is tested to USP <85> and run in duplicate, with both determinations at or below 0.05 EU/mL. Microbial contamination is screened by PCR, which reported no detectable microbial DNA. Elemental impurities are measured by ICP-MS across arsenic, cadmium, lead and mercury. Those three panels answer what is in the vial besides the peptide — a different question from purity, and the one a purity figure alone cannot speak to.
The cadence behind that certificate is also real rather than a single showpiece lot: the laboratory’s own index records 21 certificates for Level Up across seven submission dates between May 26 and August 18, 2026. Freedom Diagnostics prints no laboratory accreditation on these certificates, so none is claimed here.
Level Up Peptides is US-based. All products are sold for laboratory and research use only.
