OTC PCT should be fine. XI-KT is very mild in the world of hormonal products.
I think you will like the results. As Icarus pointed out you may see some mild muscle gains, but mainly a nice recomping/leaning out effect depending on diet and training. It will help preserve muscle while cutting.
Its also a "good feeling" product. meaning its enjoyable to run and should make you feel great in the gym and in general.
Ive used DCP v1 a few times and like it a lot.
can't wait to see what this does for you
