Help with Primo addition

Hey all. Wanted to see if I could get a little advice on my current cycle. I’ll try and provide as much pertinent background information as I can. Previously, I have ran test only, test +dbol/proviron, and test +var. Test E ranging from 200-500 per week for those cycles. I do not need a regular AI, although on the dbol cycle I think I had to pop 5mg once or twice. I have never had any issues worth complaining about, blood pressure gets a little high and lipids are not good at end of cycle, but everything always right back to normal after a couple weeks post PCT.

Ok, onto current cycle. I have really wanted to try primo after reading all the great things about it. I planned for a nice long 16 week cycle at moderate doses 300test/300primo. Well, by the end of the first week, I felt worse than I ever had on cycle. Lethargic, I just wanted to sleep all day and very moody. I immediately recognized this as likely being crashed e2. So starting week 2, I changed to a 2:1 ratio, 500test/250primo. I am now at the end of my third week and I feel relatively back to normal, mentally at least. However, I am still left with painful, popping joints. Never had joint issues in my life, usually lift heavy with zero issues. I can barely do squats right now, other joints are not that bad, but man my knees are brutal.

What do you recommend for a quick turnaround solution? I planned on getting bloods done about week 6, so hoping to get this cycle dialed in before then. Is dropping the primo my only option? (I have 6 more vials, so would prefer not) Or, if primo does completely crush my e2 as I suspect, would throwing in some npp or deca be a good option for me? I have never considered it specifically because the term “deca dick” exists, but it seems to be the only recommended AAS for joint relief. I am already taking plenty of fish oil, some collagen and the usual laundry list of vitamins/supplements. Any other ideas? Thanks in advance.

I would drop the Primo and, if you have the availability of supplies, retune it back to a cycle you previously did. Primo is also one of those things that is typically run in a much higher dose if any kind of mass is your goal. Its pricey and usually in low mg/ml which makes it a pain.

I plan on running a higher dose of hcg when I start the primo at 500 test/ 400 primo. I run 20iu eod now. Will be running var / winstrol towards of end cycle. Curious to see what happens to my e2. Afaik, primo will just act as an ai from a binding perspective, but the estrogen is still there.
