The reason everyone always advises guys to use test only on a first cycle is because you don’t know how your body will react to it. If you have multiple compounds going then you cannot pinpoint what is causing any side effects that you may get. For that reason I would say that the tbol should probably be reserved for either another time, or potentially the last four weeks rather than the first four.
You said you’re 178lbs but didn’t give us your height. That’s a factor. Your bf range is kind of wide. The difference between 10% and 13% is a lot. I’m not saying you need precise measurements in order to satisfy strangers like me on an anonymous forum, but before you start anything try to get a very accurate reading so that you can track your progress more closely.
You should have an AI. Not everyone responds to testosterone the same way, so you’ll have to dial in the dosage and do some trial and error. Hell, some guys don’t need one at 500mg and I need 50% more than my doctor originally prescribed for my TRT dose of 200mg. Everyone is different. But have it on hand before you start.
At 23 you’re on the younger side. You probably don’t really need to run a cycle just yet, but if you’re going to do it then make sure it’s done right.
Don’t bother with a natural test booster while on pct. I haven’t seen any evidence that they work in a meaningful way. Read the stickies here about pct and what’s recommended. More and more I’m seeing guys eschew Clomid and using just Nolva on its own.
As far as your goals go, I imagine you may get some pushback for not having a number in mind. But I get what you’re looking for. It’s the old Potter Stewart definition of pornography, “I know it when I see it”. But be careful. If you don’t have a healthy respect for reality then you could end up being unhappy with the results (they can always be better, we can always do more, push harder, etc) and it could lead you down a dangerous path. We talk about the physical aspects of steroids, but sometimes we forget about the psychological ones. You can change your body rapidly, break through plateaus, and generally feel invincible. But that comes with a cost. Because when the cycle is over you start a mean reversion. And then it becomes “If I run another one and add X and Y then I can get even better”. So just be mindful of your goals and control your expectations.
