Unexpected rise in hematocrit after low‑dose Testosterone Enanthate – how I managed it

Posted by rationaljenna in Safety & Side Effects - 14 points, 4 comments.

Hey everyone, tbh I started a very mild TRT protocol a few months ago because my labs showed borderline low testosterone and I was feeling sluggish and my sleep HRV was dropping. I went with 100 mg of Testosterone Enanthate injected weekly, thinking it was the safest start. For the first six weeks I felt more energy, my libido improved and my morning cortisol looked a bit lower, so I thought all good.

Then my routine bloodwork came back and I saw my hematocrit had jumped from 39 % to 45 % even though I’m a female and normally stay in the low 40s. I didn’t have any symptoms – no headaches or dizziness – but the increase surprised me because I was only on a low dose. I read that testosterone can stimulate red blood cell production, so I added a low dose of aspirin and started drinking more water, plus I scheduled a phlebotomy after another month.

My next labs showed hematocrit back down to 42 % and I felt fine. Has anyone else seen this at similar doses? Any tips on monitoring frequency or natural ways to keep it in check, especially for us women?

No? Thanks.

  • skeptical_nomad: That is a pretty sharp jump for 100mg, tbh. I have seen this happen with some guys on way lower doses too. It is kind of a wild variance. I usually prefer to see the actual data before jumping to a solution. Aspirin is one way to go, but for me, just staying hydrated and keeping a close eye on labs was the only thing that felt safe. Did you see any change in your blood pressure or just the hematocrit? I am always skeptical of "natural" fixes for blood viscosity. You should definitely talk to y
  • rationaljenna: I didn’t notice any blood pressure rise – my cuff stayed around 112/70 the whole time, so the only change was the hematocrit spike. I agree staying hydrated is key; I upped my water to about 3 L daily and that seemed to help. I’ll keep the aspirin as a safety net but will focus on weekly labs for the next two months, just like you suggested. Thanks for the reminder to keep the doctor in the loop.
  • cole_trains: I agree that the variance is strange. For me, keeping a steady water intake seemed to help, though it could just be placebo. fwiw, I found that staying lagom with the dose and not overdoing the supplements kept my blood pressure stable. It is always better to trust the bloodwork than a feeling.
  • rationaljenna: Thanks, cole_trains, I totally see what you mean about not over‑doing the supplements – I stopped the extra vitamin D and magnesium just before the phlebotomy and my BP stayed flat. I’ll keep the water steady at around 2.5 L/day and watch the dose; maybe a 75 mg weekly split will be enough now that the Hct is normal again. Have you noticed any change in your own HRV when you cut back?
