On the contrary... if u read the February Muscular Development .. Dave Palumbo advises against taking t3 with gh because even taken at 25-75 mcg/ed will only increase fat burning effects of gh by 7%... he also advises against taking T3 in low doses to increase protein synthesis for prolonged periods of time stating it should only be used 6-8 wks prior to a contest... I dunno what is true since so many studies contradict each other im just offering another poing of view
