for tren and or deca use i use 1mg caber e4d......5 adex fir the high test and i save letro for when the nips have little lumps behind them or get really sore, but the caber helps with all that
deca and tren together is hardcore. the anxiety, sweats etc were hard. i would run one or the other then switch...ie run deca/test, then switch to test/tren esp to cut
