Wow! 2 well-known members going at it. Showtime! I think you both have made excellent points in your statements. Yes, heat does and will sterilize, but too much heat will compromise and can damage certain hormones. Brewing gear is definitely a fine balancing act. So, my 2 cents is that you are both correct. For gear such as Tren, minimum heat should be used, and I've also hear of using no heat for brews like Tren. It seems using heat is a personal opinion, but too much heat on certain hormones will defiantly damage sensitive hormones. I personally use minimum heat in Tren brews, mostly because gear is easier to filter when warm, and the hormone seems to suspend a bit sooner in the carrier oil. So, the debate continues...does any other well-known members have any thoughts or input on this subject?
