Yes I check it 2x a day it stays 125/60 before I started trt in December it ran 105/55 with a rhr average 45 now rhr is 55 , also take Reta 2.5 mg
Your naturally low BP is the biggest clue.
Edema is a common rHGH side, and usually resolves after a month or two as the body adjusts.
11lbs weight gain isn't mild edema that can be fixed by waiting it out or adjusting sodium intake. It's "Fluid overload" and you have to address it.
Your low natural BP means you have low vascular tone. A good thing, Your blood vessels are relaxed and flexible. But that also means they're more permeable than someone with higher baseline BP, so water can escape capillary walls more easily (blood cells are too large to pass).
Because that's your natural state, everything else that regulates water retention has compensated for this. Mainly your kidneys and how much sodium they keep or excrete to keep everything in balance.
But you've got two things overriding that balance now. TRT raising your blood pressure, and rHGH increasing the permeability of your blood vessels.
So your choices are:
Significantly lower or eliminate the rHGH
Lower or eliminate the TRT to reduce blood pressure. (a BP med won't help here, as it'll reduce your vascular tone more and worsen the problem).
Since we're here for performance enhancement, not under medical treatment, I'm going to assume eliminating one or both of those is unacceptable.
What a doc would do for a patient with fluid overload but who must be on rHGH is add very mild diuretic. 12.5-25mg HCTZ, aka Hydrochlorothiazide.
This, combined with the natural rebalancing that will happen over a few months should completely resolve your issue.
Look up precautions. but for healthy people it's basically start with 12.5, stay hydrated, check electrolyte bloodwork in a few weeks. If you still have water retention and everything's ok you can increase to 25mg. Overall it's a very safe, common diuretic, easily available from the PCT sources here or telemedicine. And stop using it if you drop TRT. It could. drive you into hypotension since your baseline BP is low.
