⚠️ CONFIRMED COA FRAUD. Multiple 2026 Trustpilot reviewers report batch IDs on received vials that do not match any published COAs. Freedom Diagnostics (the claimed third-party lab) had no record of the batches when contacted directly. Additional red flags: customs fraud (a $650+ peptide order declared as 'peppermint essential oils' valued at $30 — exposes buyer to criminal customs liability), black mold found on SEMAX nasal spray dropper, rubber seal popped off causing leakage, unresponsive CS on COA requests. Trustpilot 3.3/32 reviews.

"Found black mold contamination on SEMAX nasal spray. Multiple unanswered emails."
"Batch ID numbers didn't match any COAs on their website. Over one month without support response."
