Janoshik tested this TB-500 + BPC-157 blend, with results showing three measurements per component (likely three separate vials). BPC-157 measured 5.71 mg, 5.57 mg, 5.66 mg, and TB-500 (TB4) measured 5.80 mg, 5.73 mg, 5.86 mg. No purity or endotoxin data was provided, and the assessment appears quantitative only. The test is recent (under 3 months), and customers can cross-check on the lab's public verification URL.
