You have to decide the doses that you want to use, most of us don't buy the blends because you can't really control the doses so if you want your testosterone higher then your trend you're going to have to take the test C with it.
As far as your pinning frequency you have all fast esters you need to pin daily or every other day at the least with that tri blend. The test C you can take once or twice per week but anything with an acetate or prop ester, you need to do daily or every other day.
Your question makes it sound like this is your first cycle, you don't want tren or any kind of blend on your first cycle.
If this is your first cycle I would very much suggest you consider only running testosterone and figuring out how you manage your estrogen and side effects from that over the course of at least 8 to 10 weeks before adding in anything else.
And regardless of whatever you do you're going to want an anti-estrogen on hand. If you decide to run the trend anyways and you're going over 150 mg of that per week then you're going to want something on standby for prolactin just in case. Or start p5p 2 weeks before the tren
