COA & lab verification
⚠️ 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.
Review Highlights
Positive
"Fast delivery — ordered Sunday, arrived Tuesday. Rewards program and creator codes bring prices down."
"Five orders with zero issues. Consistent 2-day delivery and peptide quality is solid."
Critical
"Order over $650 never arrived. Customs declaration listed contents as 'peppermint essential oils' valued at $30 — customs fraud that exposes the buyer."
"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."
