You're about to see this narrative EVERYWHERE: "You don't know what product you're getting from research companies." It's already spreading through media outlets, regulatory discussions, and it's about to be weaponized hard. There's just one problem... It's complete bullshit. And if you know anything about COAs and third-party testing, you can call it out immediately. Let's talk about why this narrative is garbage and arm you with the facts to shut it down. Third-Party Testing IS The Standard Here's what they won't tell you: Whether a peptide is compounded in the US or manufactured in China, third-party testing is the standard. Not sometimes. Not "if you're lucky." It's the baseline. And here's the kicker: The research space does this BETTER than almost anyone. This is exactly why third-party testing is a hard requirement for any vendor on PeptidePrice. No COA? Not listed. Period. What Third-Party Testing Actually Tells You When someone says "you don't know what you're getting," they're either ignorant or lying. Here's what comprehensive testing reveals: THE CORE 3 (Absolutely Non-Negotiable) 1️⃣ IDENTIFICATION - Confirms you actually have the peptide you ordered - Uses HPLC or mass spectrometry to verify molecular structure - This isn't a guess—it's chemical proof you got tirzepatide, not mystery powder 2️⃣ NET CONTENT (Quantity) - Tells you how much peptide is in the vial - Ordered 10mg? This confirms if you got 10mg, 8mg, or 12mg - You're paying for a specific amount—this verifies you received it 3️⃣ NET PURITY - The percentage of desired peptide vs other substances - 98% purity = 98% target peptide, 2% related fragments - Higher purity = more predictable results, fewer potential side effects These three answer: "Is this the right peptide, in the right amount, at the right quality?" If a vendor can't provide this, RUN. THE CRITICAL NEXT LAYER 4️⃣ ENDOTOXINS - Bacterial toxins that cause immune responses (fever, inflammation, septic shock) - Measured in EU/mg (endotoxin units per milligram) - Most research peptides target <1 EU/mg, many aim for <0.5 EU/mg - This is HUGE for injectables
