However, would you recommend using only testosterone?
You said you are currently natural , so I'm going to write this assuming that you do not have any long term data on how you respond to exogenous testosterone use or other anabolics.
The worst plan would be to go from totally natty- to blasting test and primo
I'm assuming you have the primo because you've heard advice to use it to control estrogen
But you don't even know how much you aromatize and if it's needed and / or would be effective for whatever e2 level you land at.
This isn't something where the universe has written a default plan and everyone gets the same experience from doing the same thing
You have to get some experience under your belt and understand one thing at a time or you will just end up an unhealthy mess with all the side effects and none of the benefits.
If you have never used exogenous test.... start at trt levels
Go get your natty bloodwork done. Lots of info in the serum blood testing forum about what tests to order. At the very minimum, get as many general health biomarkers checked as you can, lipid panel, all that stuff.
For pre-testosterone use, at a minimum get: Total test, Free test shbg, dht, estradiol (LC/MS method, not Immunoassay), CBC
For pre-hgh use, at a minimum get: IGF-1, a1c, insulin, and cystatin c to make sure your kidneys aren't already impaired.
I say to use HGH for life because it is not beneficial to cycle it. It takes at least 6 months to start getting any benefit from it. Its the kind of thing that you either use, or you don't. Using it off and on is nonsensical.
If you decide to start test after your bloodwork, realize for yourself that using exogenous testosterone is chemical castration. Your nuts will stop working. Do a lot of people get lucky waking them back up if they want kids or to stop using test every day? Yes. Does everyone get that luck? No
So go into it assuming that you are just gonna chop your balls off and be reliant on putting testosterone into your body from an outside source for the rest of your life.
Spend 4 months or so trying to find your max tolerable dose of testosterone without needing an ai
Because you likely aren't going into this already deficient- start at low trt levels. 75mg-100mg / week. It will take some time for your balls to die, so on that dose, your test and estrodial are going to shoot way up at the beginning because of having natural and exogenous testosterone at the same time. You will feel your balls shrivel up and fade away as they shut off. that's how you know it's working
Run it for 40 days. Get bloodwork checked again. See how much you aromatize. If you are getting gyno or other high e2 symptoms, reduce the dose and check again in 40 days.
If after some time at low trt levels you aren't crying when you see the clouds and you aren't growing breast tissue..... up it a little bit and see what happens.
Once you find the spot you can't 'run it without an ai.... you found your max tolerable dose.
And congratulations.... you just ran your first cycle. Hope you were training hard and eating right to take advantage of the elevated testosterone levels you had.
Now you have to decide if you are going to go all the way off test, PCT and try to wake your balls up
Or if you are just gonna be a lifer and "cruse".
Next cycle, start with what your max tolerable dose was last time, slowly ramp it up from there to like 300mg/week, and have the AI ready for when your nips start getting sensitive. BUT, don't dose your AI according to feels only. Bloodwork is what drives drug decisions.
So there you go. 2 first cycles, plus maybe hgh
