Test/Primo Cycle help

So I hate to be annoying with another post about how to run a cycle, but don’t get me wrong. I have done an extensive amount of reading everything from pubmed studies, forums, YouTube videos…and I have a couple of ideas of how I want to run this, but before I begin, I also wanted to ask you guys for input.

I have basically an unlimited supply of test c 200mg/ml

I have 2 vials of primo 150mg/ml

20mg nolva

I am looking to stay 12 weeks or less for cycle. How would yall run this? Thankssssss

For the record, I am thinking either 300 test/200primo or 500 test/300 primo. Any advice is appreciated greatly

How can any advice be given when you tell us nothing about yourself or the goal of this cycle.
Past AAS use?


I am 29 male, 5’9 192lbs, not a fat body type but have a pretty significant “beer belly”.

I’ve been significantly limiting calories and carbs and trying to shed some weight in addition to my workouts.

Ideally I would like to put on lean muscle mass without adding much body fat. However at the end of the day, I want this to be a bulk, whatever happens to my belly happens and I will cut later.

I want to add as much mass I can, as safe as possible, minimizing side effects. I’d rather not use an AI and so I had thought maybe if my estradiol gets high, I could add the nolva. I’m hoping though, primo will keep the estradiol down without crashing it.

I’ve only ran test c in the past. “Trt” but in doses higher than necessary for me. Most I’ve ran was 250 a week so still what I’d call a beginner.

Agree. Post a pic and lets see what we are working with. Gut reaction is that you are carrying too much bodyfat and should drop more before you consider doing any gear.

Primo doesn’t always work as an AI. You might run a 500 / 300 cycle and still need an AI. Or you might crash e2. One of the benefits of running a test only cycle is you get to learn how your body aromatizes, and when your body requires an AI. If you already have a feel for high & low e2 and how to handle it, then never mind. Otherwise I recommend running that first T only cycle until you get a good feel for how to handle e2 sides.

Thanks for a response!

I was looking more for a hypothetical, not looking to post pics and all that like some have asked. And I understand why but we also know the general mechanism of these drugs and I am more looking for opinions on the general mechanism and how to use rather than expecting someone to tailor something specifically to me, because they can’t anyway. I can post pics but my photos aren’t going to qualify anyone to write me a cycle. I’m simply looking for a hypothetical. So thank you for an actual reply, sir.

I have ran test only but not as high as 500 and I doubt I’ll ever go that high honestly. Never say never though.

I know on 250mgs and an ai my estrogen was crashed (this was a doc’s orders and before I had any idea what I was doing, I currently run 200mgs no ai), and even though estradiol was crashed I struggled with gyno. Any ideas? Prolactin? This was in the past. I am just trying to think about issues with my upcoming cycle. Thanks
