+ 1 Quick question?

Hello everyone, just wanted to see if any of you can guide me or give me an advice. So I am on my last 3 weeks of my 16 week cycle and I just noticed that for a couple of days my libido has been going down, like my sex drive is just shutting off on me.
I am currently doing just NPP 450mg weekly and test c 600mg weekly. I know it’s now the test since I have been using the same test and batch through out my entire cycle and believe me, my libido and sex drive was on point, it was great up until now.
Any suggestions?
Thanks! And have an amazing weekend!

Proviron
I just ordered some
This is the very reason why I never opt to run nandro. Caber helps but my decreased mood, sex drive and increased bloat are unavoidable with this compound for me which is why I wont use it ever again.
You know what bro, I always have some type of issue at some point through out my cycle when I use nandro, I will try Proviron and will do some labs as well.
You’re better off never using it. It works very well for others, unfortunately not for me. I think I’m finished with 19 nors all together. I’ll stick with my primo.
That’s gonna be my next cycle, primo test and anavar, I love primo, have you noticed that the 200mg presentation is always out of stock? Do you use clen?
I can’t tolerate Pip on 200 mgs but I was told there will be a major shortage on primo in general in the upcoming months. I used to use Clen but not anymore. I’ll post some chats up on why.
Brother, what you're experiencing is textbook “late-cycle androgen fatigue.” You’re not crazy, and your test didn’t magically stop working. Here's what’s most likely going down, again support with knowledge for you to read to learn more
Progestin Load From NPP
NPP (nandrolone phenylpropionate) is a 19-nor compound, and even though it's milder than Deca, it still carries progestogenic activity. That can cause:
Lower dopamine (which affects sex drive)
Decreased libido despite high test
Possible prolactin spike even with no gyno
That’s why a lot of guys feel like gods weeks 1--10, then suddenly dead below the belt.
Estrogen-Progesterone Imbalance
Test at 600mg..... You’re aromatizing plenty. If your estrogen is high and prolactin is climbing due to NPP, that combo can wreck sex drive fast.
Bloodwork is key. Check E2 (sensitive) and prolactin ASAP.
Consider adding Cabergoline (0.25mg 2x/week) if prolactin is elevated.
Or drop the NPP now and let the test ride solo to the finish line.
CNS Overload
High androgens for 13+ weeks straight can absolutely fry your CNS. You’re pushing dopamine and norepinephrine nonstop. Eventually, it taps out. Think of it like pre-workout.works great until it doesn’t.
High SHBG or Receptor Desensitization
Unlikely in 16 weeks, but possible. If your free test has dropped or your androgen receptors are desensitized, you’ll feel that libido crash too. labs help!!
Your Fix Try this.....
Drop the NPP now (you’ve already pulled the gains from it)
Stick with test solo for the last 3 weeks
Add Proviron 50mg/day if you want to turbocharge libido & SHBG control
Run bloods immediately: Estrogen (sensitive), Prolactin, SHBG, Free Test
Optional: low-dose Cabergoline if prolactin is the problem
Don’t ride it out and hope for the best, dial it in before PCT so you don’t crash harder post-cycle.
Dial the hormones, finish strong, and go into PCT with your libido still intact.

Brother thank you so much, that was great info
Are the women you're looking at actually attractive or were you experiencing a rock on for anything with a pulse?
lol I’m married, and I am very attractive to my wife, as I mentioned I would annoy her because I was just like 17 year old when my libido was on point.
What AI are you using at what dose? What about a dopamine agonist for the nandrolone? When’s the last time you had bloodwork done? Could be low estrogen, or high estrogen, or a prolactin issue, which likely means you also have high estrogen.
