These laboratories can perform the full suite of tests required to confirm peptide identity, purity, potency, and safety, including liquid chromatography-mass spectrometry for definitive structural confirmation, peptide sequencing to verify the correct amino acid order, residual solvent analysis by gas chromatography, heavy metal screening by atomic absorption spectroscopy, and microbiological testing to ensure freedom from bacterial and fungal contamination
For veterans who don't qualify or face months-long waitlists, PlexusDx offers licensed compounded semaglutide injections at $189/mo month-to-month, or from $149/mo on the 6-month plan without insurance requirements or membership fees
