Yes, this is my first cycle. Its only one bottle so thats why i was just gonna run it now. I was already thinking about running mast for my next cycle in the summer, but if i did do that, i was gonna go with mast eth so i could keep it on the same pin schedule with my test. since the one bottle i got for free was prop, thats the only reason i was thinking of just using it now. But either way, i would still need to learn the proper dosing protocal for both of them (eth & prop) and also if it can be loaded together in the syringe with test
