I only ordered the Phena Lean because I saw it on Labor Day during the sale. I was skeptical, but while recovering from an injury, I figured I'd try it. DEFINITELY START WITH ONE! If you take two and just sit around, I wouldn't call it a comfortable feeling... Thumping heart, clammy hands, etc. That said, after taking it for two weeks I went running this morning and weighed myself after. I'm a pound below my target goal! Definitely don't think I'll reorder once I'm at my next target goal, but thrilled I have it to help me get there!
