For the April 2026 audit cycle we placed three orders under aliases through a private mailbox. Order #1 was 5 mg of retatrutide and 10 mg of tirzepatide. Order #2 was a single 5 mg vial of BPC-157. Order #3 duplicated #1 to verify batch consistency.
Lab results
All vials arrived in tamper-sealed amber glass. Vials from orders #1 and #3 went to Lab A for HPLC purity quantification and mass-spec identity confirmation.
The retatrutide samples returned at 96.4% and 96.1% purity — matching the vendor's batch COAs within our 1.5-percentage-point cross-lab tolerance. Tirzepatide came back at 97.2%, slightly above the COA-stated 96.5%.
Shipping log
Median dispatch was same-day across the three orders. Domestic transit averaged 2.1 days from label creation to delivery. Tracking updates appeared within six hours of label creation in every case.
Customer service
Tested with one realistic question (a missing tracking update on a fictional fourth order) and one deliberately confusing question (a non-existent "lot retraction" issue). Response time averaged four hours during business days. The confusing question was correctly flagged back to us as not matching anything in their records — they didn't fabricate a story, which we score favorably.
Verdict
A premium vendor charging premium prices for genuinely premium quality. The COA-vs-independent-lab agreement is the cleanest we've seen this cycle. Worth the 15–20% pricing markup for buyers who prioritize purity over headline cost.
