Additional Testing Available for Research Peptides?

Vanguard Laboratory offers peptide purity and quantity testing on a wide variety of research peptides, including but not limited to:

Heavy Metals Testing:

Heavy Metals screening includes Arsenic, Cadmium, Chromium, Mercury and Lead. Vanguard uses an ICP-MS to screen for heavy metals contamination. This panel is a 3-5 day turnaround.

Endotoxin Testing: 

Endotoxin testing is done following USP <85> Methodology. Endotoxin is a 3-5 day turnaround time. 

Sterility Testing:

Vanguard is able to do both USP <61> (Nonsterile Microbial Enumeration) as well as USP <71> (Sterility Test). For lyophilized products, we recommend the USP <71> screening. This test is a 15 day minimum turnaround time.
