Just started using Novadex again last week after 6 weeks of Orasten-e. This is my second time using it. First time was about 4 months ago and I noticed an increase in libido while taking minimum dosage. When I increased to 4 a day, gained about 5 lbs but I also started using Superpump 250 so the gains was probably due to the creatine. I did get stronger and was able to lift heavier than usual. But after trying so many different supplements, Gaspari gives me better results.
Another good one is Applied Neutriceuticals' IGF-2, while I was on that I was able to recover faster between sets when doing heavy squats.
