The Triple-Tier Quality Assurance Framework
Every batch of ProstaPeak® undergoes a rigorous three-stage analytical screening process before release into clinical distribution:
Tier 1: Raw Material Botanical Authentication
Prior to acceptance into the manufacturing suite, all incoming raw botanicals undergo High-Performance Thin-Layer Chromatography (HPTLC) and Fourier Transform Infrared Spectroscopy (FTIR) testing. This verifies botanical identity at the species level (e.g. authentic Prunus africana bark vs. adulterated alternatives) and confirms absence of synthetic spike agents.
Tier 2: In-Process Blending & Gravimetric Uniformity
Capsule filling is performed in climate-controlled ISO Class 8 cleanrooms utilizing precision automated encapsulators. Gravimetric fill weights are tested every 15 minutes to guarantee that each capsule contains the exact therapeutic concentration of active compounds within ±1.5% analytical tolerance.
Tier 3: Finished Product Analytical Release Testing
Representative samples from each finished lot are quarantined and shipped to independent ISO-17025 accredited analytical laboratories for third-party validation. Finished products are tested for active potency (HPLC), heavy metals (ICP-MS), and microbiological bio-burden (USP 2021/2022).
