Episode notes
Welcome back, warriors! In this week's Peptide Q&A, JD Denham and William T. Haas are live from Prague after touring the Janoshik testing facility the gold standard for independent peptide testing. They break down what they saw, how COAs actually work, what testing really costs, and answer questions on fat loss at 447 pounds, chronic pain peptides, and the hardest peptide to test.
We cover:
• Inside Janoshik: What the Tour Actually Looked Like: Why Peter Magic's team does things right, what the petri dish sterility test looks like in person, and why endotoxins are caught at the supplier stage
• How COAs Actually Work The Full Breakdown: Purity vs. identity vs. content testing, what HPLC and mass spectrometry actually measure, and why a COA without all three tells you almost nothing
• What Peptide Testing Actually Costs: $450 for HPLC, $105 for heavy metals, $180 for endotoxins, $290 for sterility and why that math explains why cheap products can't be properly tested
• The Hardest Peptide for Janoshik to Test: Why Cerebrolysin tops the list, why it's made from pig brain and contains multiple peptide strains, and why Retatrutide is challenging due to its molecular weight
• Opiate Painkillers Post-Surgery When to Get Off: Why ibuprofen often works better than Vicodin for actual pain, why ARA-290 is the peptide answer for nerve pain, and why hyperbaric chambers and red light accelerate healing
• 447 Pounds Down to 380 What to Stack with Retatrutide: Why TRT is non-negotiable first, why HGH at 2 IU is the long play, and how SLU-PP-332, 5-Amino-1-MQ and L-Carnitine target fat through different pathways
• Carnivore + Retatrutide Does It Work?: Why you can absolutely do both, when to use carbs strategically around training, and why intermittent fasting compounds the results
• The Culture at Janoshik: Why Czech work culture prioritizes quality over speed and what American businesses can learn from it
