New to using PHDs and I'm trying to improve my endurance and performance with long distance running. I have 3 half marathons and two full marathons beginning the end of August and ending in November with the New York Marathon. Just curious - does anyone know of problems associated with using both Testosterone and small doses of Halotestin at the same time? Or should Halo be used independently of any other PHD?
