Bulking with TRT dose of test C + NPP?
ad
Hi everyone,
I have run a few cycles in the past of just high testosterone cypionate (last cycle 800mg/week). Blood work showed my estrogen was extremely high but mentally I felt fine so I stuck with it. However, looking back at photos I was obviously bloated with water and facial fat even though my abs were visible throughout.
For my next cycle I don’t want to be a bloated mess and keep my bf under 15%. My idea is to use my TRT dose of test C (80mg/week) that keeps me at about 800ng/dL of total T and at a normal range of estradiol. On top of that I will add 400mg/week of NPP every other day. If blood work shows high estradiol I will add primo to lower it.
For reference I’d like to get to a Frank Zane level of mass and leanness.
Any thoughts?

On that ratio, just be careful with deca dick. Primo’s a slow, long-term builder, so I’d honestly save it for another run. Since you’re including a 19-nor, I’d personally add some mast … it’ll help with libido, keep you drier, give you a mild AI effect, and overall improve drive and mood. Other than that, your plan looks solid (I’ve seen many people doing something like that)… just keep an eye on bloods and adjust from there.
My advice is to get really lean before any cycle, being too fat will definetely increse your aromatization rate and give you more side effects than you want. Also being lean you will have a much better response to food which will in turn again give you way more out of your cycle.
I also do small cycles with my TRT and I was always a fan of Primo since I am a high E2 guy too. Elevated E2 isn't a problem right away since it is more about the ratio of Test to E2 and if your Test is elevated too your E2 can get a bit out of range as well but up to a point where you start to experience side effects. This level is different for everybody and I still feel best with my E2 being in range or just slightly over during cycle.
Primo is a huge AI for me so you have to be careful not to overdo it. I always start at a 2:1 ratio of Test to Primo and get labs after 4-6 weeks to adjust if needed.
You definetely don't want to tank E2 since E2 is very anabolic as well, you need it. So if you use primo or any other AI start low and adjust with blood work.
Really man all you need is some anastrozole and it would solve your estrogen problem. You start adding in NPP all the time then you will need caber for prolactin.
Why not just use some Aromasin in your cycle?
I wanted to keep the number of compounds in my body minimal so I was avoiding adding an AI, I could still see my abs and I didn’t notice the face bloat until later. Ideally for the NPP cycle my estrogen would stay in normal range and I could avoid needing primo or an AI. One study on deca found 0% aromatization (https://doi.org/10.1093%2Fhumrep%2F16.12.2570)
400mg of NPP is just too much without an AI or primo/mast in there. Your E2 is definitely going to be out of range. It doesn't sound like you're in a rush to pack on mass, try 100mg NPP and see where your E2 is. After 4 weeks, bump it up to 200mg and see where your E2 is. Keep titrating up until you reach a point where E2 is too high then lower the dose back down. Write it down and keep it for future referrence. As far as using Primo instead of an AI, in the bodybuilding mass world it works great, but if those arent your goals, 12.5mg of aromasin is much less total mg of compounds being run and strain on the system then adding in 400mg/week of Primo just to manage E2.
A TRT Clinical Npp dose is 50mg. That is where people notice very little change in E2 and still reap the benefits of the joint support and will add on more mass then just test. It won't be crazy like 400mg/week but you can avoid the side effects and still get a little trt boost which sounds like your goal.
400mg/week is going to raise your prolactin and you will 100% need to take some type of support to prevent that. Either P2P/L-Tyrosine/L-DopaMucana/Magnolia Bark, or you take caber. But caber is being studied more and more and its negative impact on the heart and the dopamine brain pathways being long-term even permanent is shifting the majority into using supplements listed above.
Don’t waste the primo using it like that. Otherwise, everything else is fine. Plenty of people just keep their TRT dose then add other things on top of that during blasts.
