Test + primo / EQ - stay in top of labs

Just when I thought I had my E2 dialed in…

Started with test 50% higher than primo and had puffy nips. (Didn’t get bloodwork at that point).

Increased primo to where test was 80% of primo (yes primo higher). Symptoms gone and E2 was 35.

Increased test to run 1:1 with primo and E2 is 18. Wondering if this is due to fat loss aging the way and / or a lag from the time when primo was higher than test.

I feel / felt fine at all of these numbers. Never held water or had joint pain. I think 18 is a bit low so I’m going to lower primo down to 80% of my test dosage and re check in a month.

But I suppose it’s a lesson that 1) yes it’s helpful to stay on top of this when dialing in but also 2) things can change (I’ve gotten a lot leaner during this process, potentially impacting aromatase levels), and 3) don’t get too lost in the weeds chasing these numbers.
 
You've got to keep in mind that bloodwork is a "snapshot" of a point in time of a constantly fluctuating system.

In an ideal world, you'd want ~3 daily measurements (AM/MID/PM) from each day in your injection rotation. That'd give you a REAL picture of what your levels are like.

But, that's not economical :(

Case in point: Bloods taken on same dosages/compounds, at different days/times

E2
  • 91 pg/mL on September 11, 2025
  • 273 pg/mL on October 6, 2025
Test
  • 1610 ng/dL on September 11, 2025
  • 9057 ng/dL on October 6, 2025

My $0.02: Ultimately, if you FEEL good, leave it alone.

If anything, I'd increase Test slightly vs dropping Primo, but that's splitting hairs.

Was considering that also. Thanks brother.
