I purchased two vials of glp3 for research and reconstituted with pharma grade BAC for one and one purchased through Flawless. Both vials reconstituted cloudy. During the research, the product appeared to be ineffective. Switched back to another brand and felt a night and day difference. Bad batch? Who knows. When I contacted the company, they told me they would only compensate me on one vial. Research at your own risk.
