Overview

This video is an interview with Peter Magic from Janoshik, a company specializing in peptide testing. Peter discusses how he accidentally started the company, the evolution of peptide testing in the industry, the various tests Janoshik offers, and answers common questions about peptide storage, reconstitution, and the reliability of testing results.

Key takeaways

• Accidental Beginnings: Peter Magic started Janoshik by testing performance-enhancing drugs for friends, which eventually grew into a full-fledged business due to increasing demand.
• Peptide Boom: Peptide testing now constitutes 70-80% of Janoshik's business, a significant increase in the last two years, driven by the popularity of GLP-1 peptides.
• Comprehensive Testing: Janoshik offers a range of tests including mass spectrometry (LCMS) for purity and impurities, endotoxin testing, sterility testing, and CHNS analysis for elemental composition.
• Storage and Shelf Life: Peptides, particularly lyophilized ones, are very stable. While degradation occurs over time, even a decade-old human growth hormone stored at room temperature was found to be still effective. For reconstituted peptides, it's generally advised to use them within 28 days when stored refrigerated.
• Reconstitution and Water Choice: While bacteriostatic water is common for reconstitution, sterile water or saline are also viable options. Benzyl alcohol in bacteriostatic water can sometimes cause local irritation, and generic "Chinese BAC water" has been found to have zero benzyl alcohol or be unsterile.
• Testing Discrepancies: Differences in testing results between labs can arise from variations in methodology, equipment calibration, or procedural errors. Blind testing and community testing are highlighted as crucial for ensuring accuracy and accountability.
• Failure Rates: Janoshik experiences a failure rate of approximately 5% for peptides that have significantly different dosages, contain the wrong peptide, or have no peptide at all. Sterility testing failures are a separate category.
