Helios I tried about 6 months ago for 2 months. Dosage started @ .4 cc each side then worked up to .75 cc each side. Only thing it did was make me feel nauseous and shaky. No weight loss or spot reduction. If it worked I might have endured side effects but it didn't. No luck with clen either. T3 did however work pretty good for burning fat but make sure you take test with it because it will burn fat and muscle. The best fat burner I've ever used is HGH. If you can afford it, HGH hands down is the best!
