hi guys, this is my first cycle im in the middle of doing and need some help asap! im 22 years old about 165pounds.

i been taking 3 shoots a week
- tes 250 1cc
-deca 1cc.
thats 750mg of tes a week. now im almost 3 weeks into it and i want to start taking my tren . now is it ok for me to start taking the tren and tes and just finish the deca up?
i bought a bottle of tes, deca and tren 10cc of each. now im almost done with the tes and deca and i wanted to get another bottle of tes and take that with the tren. will this be ok?
