“So they really froze their testicles?” I thought I misheard the last phrase from Pessi. “They did! This technique was well known among bodybuilders in the Soviet Union. They thought they could boost Testosterone that way.” Well, thankfully, there are other effective measure one can take nowadays.   Our guest for this episode of the Flowgrade Show is the Testosterone expert Pessi Peura. As some fantastic guests of past episodes of the Flowgrade Show (like Nelli Lähteenmäki, Teemu Arina and soon to be published Jaakko Halmetoja), Pessi is from Finland, the most active place of the European Biohacking scene. The young Pessi is an active personal trainer, speaker and published author of two health books. His latest book The Guide For Naturally Boosting Testosterone helps guys to reach optimal testosterone levels. The book was published in Finnish and will be translated to English later. In this episode, Pessi and I discuss the importance of Testosterone, the reasons and symptoms of a deficiency. At the end of the episode, Pessi shares his preferred methods for naturally raising Testosterone.
