according to dat...u dont need the t4 on cjc-1295 w/o dac and ghrp-2 combo because gh levels are only spiked for a short amount of time compared to exo gh
therefore the up regulation in conversion of t4/t3 is not going on all hrs of the day as when using exo gh...
that said...when using dac the story could be different
wish there was some more info on all this....cause having the thyroid optimal would obviously... dramatically increase the results one would get while running peps or gh...if using peps or gh creates sub optimal thyroid it might be better to run neither
