I've seen a few posts here and there about hematocrit, but never everything in one place. I've explored a lot, so I thought I'd post a little on what I've found.

First, I'll say, I'm no medical doctor. I'm not a medical researcher. But I'm not a total idiot, either. I can read, and I can evaluate sources and references. Most of what I'm posting here is not just some random crap I read on the Internet. No, most of these things will be based on what "medical science" says and what I've read in actual research reports, even when they're funded by drug companies. And yes, researching this stuff pisses me off to no end because the more you look, the more you realize how incredibly hard it is to find actual information, especially related to things like steroids. But I'm not here to talk about that...

Hematocrit is, simply, the volume percentage of red blood cells in your blood. But that's where the controversy shall end.

Many people will get blood tests to try and track their health for various reasons. Hematocrit is often on those tests. Most blood tests like that have a "reference range," which many people consider "normal." So, what's normal for hematocrit? It depends. And it varies. A lot.

Some tests show 38.5-50%. Some say 40-50. Others 45-55. I've seen 41-50. Another report shows 42-54. Some (not all) give different numbers for females (36-41). Oh, but wait -- if you're at a higher altitude, those numbers don't count. No, you see, the numbers are higher for every 1,000 ft in altitude you gain. So what's normal? Apparently, based on a survey of medical journals and science, for men, anywhere from 36-60 or so.

Of course, anything outside the "reference range" means you need drugs or something to fix it, right?

Anyone heard of blood doping? You know, some athletes who have been caught doing something against the rules? Yeah, blood doping is intentionally increasing your own hematocrit. Why? So you have more blood cells to bring oxygen to the muscles so you can produce more muscle. See why this might be a side effect of AAS? See why some athletes will risk getting caught because they intentionally want a high hematocrit (even if only for a short period of time)? I also recently read a detailed report that looked at intentionally elevated hematocrit levels. They found no increased risk or danger to people with levels up to 70%!!! They also noted the performance increased tapered off quickly above 60%.

I'll ignore low hematocrit for now, as few reading this will likely have that. Instead, let's focus on the horrors and terror of high hematocrit. What's often the largest reasons given for high hematocrit? Dehydration. Yup, if you happen to get a fasted blood test first thing in the morning without drinking, you're going to have high hematocrit. #2 on the list? AAS use. This is a feature of AAS. As I mentioned, if the steroids are trying to build muscle, having blood cells to bring oxygen to them is a feature, not a bug. What else causes high levels? Sleep Apnea. Seriously! If you're not sleeping well, your body might produce more red blood cells! Of course, most medical providers will focus on the thought that you're having a heart attack and start collecting cash, err, I mean, treating you for that.

So if you actually have "too much" hematocrit, what is that? That's a condition often called polycythemia. In general, this is a genetic condition with no cure. The symptoms? dizziness, headaches, vertigo, fatigue, easy bruising, and so on. Gone untreated, this can lead to things like heart attack and stroke. So if you truly have too many red blood cells, this can be serious. But I'll refer back to the start of this article to let you determine how much is "too much..." and you can tell me how many symptoms you happen to have related to having too much...

-----

Again, I'm no doctor. I'm not giving you medical advice. But I also know 99% of the medical industry is useless here. Anyone invested in the medical industry will not help if you say, "Hey doc, I'm taking tons of steroids, and I'm trying to manage my hematocrit levels. Can you help me ensure I'm within norms and safe?" No, the answer you're going to get 99% of the time is, "Stop taking steroids, and you're lucky I don't call the cops." (I know some of you have close relationships with doctors and can tell about exceptions, but that's why I listed 99%).

If you want to donate blood, donate blood. It's a nice thing to do. From what I've read and researched, drinking (or not drinking) a couple gallons of water will have more of an effect on your hematocrit levels.

So, we have to rely on one another and our experiences and research. I am NOT saying to ignore your hematocrit. I realize that every single person is different and I really believe every single person's body reacts to different things in different ways. Here is what I would suggest, based more on years of reading and studying, as opposed to my own, personal experiences (because there's a 0% chance your body is exactly like mine): If you're going to use AAS, get a blood test before you start. After that, get regular blood tests. Watch the numbers, but ignore the "Reference range." The reference range isn't for you and doesn't apply to you. If you want to be in the reference range, stop taking drugs (all of them). Is there risk? Sure. Are you going to die of a heart attack tomorrow because you were 0.1% above the reference range? No, but you might get hit by a car, anyway.

Do what you need. Adjust how your body tells you. Use a mix of blood tests and feelings. And maybe one day, in the far future, we will have an industry that will help those of us who just want to help ourselves.
 
Great post. I'm heading in for labs a little later today. I'll see how much dropping the vitamin C has reduced my hematocrit from last time.

Edit to add: Sleep apnea, smoking, overweight, there are lots of reasons for your body to produce more red blood cells to push more oxygen. The doctor's freak out level is usually what determines the severity of the diagnosis.
 
Great thread. I went off trt for two months now b/c doc was concerned. Felt like shit. Following and will try to provide some insight.
 
for the cyclists blood doping i know that they raised their hema so high they would all wake up in the middle of the night to cycle to push the blood through. so i know there are dangers with how high those fuckers were pushing it. beyond that I agree. if youre 1 or 2% high, and exercising a ton, youre probably fine. drink more water, drink some before the fasted test. see how you score.
 
I appreciate the post. Doctor diagnosed me with polycithemia, said to give blood every 2 months. Think I'm gonna drink more water.
Did he confirm by testing for JAK2 gene? Probably not. These doctors are quick to assume and treat without knowing the how or why. This is referred to as “idiopathic”. They are “treating the symptoms” rather than finding the actual cause. Pretty much how western medicine operates.
I wonder how many dickhead docs cry polycythemia when the numbers are a few degrees off?

The increase in blood cells from testosterone use is not defined as fact. Read the studies. They are as conclusive as global warming.

I wouldn’t have thought this way twenty years ago, but now I wouldn’t doubt this is part of the emasculation of all men in society. Remember “toxic masculinity”? Can’t be giving drugs that might cause that. Now they use hematocrit as a tool to wave the warning flag.
 
I've had one blip over the past 2 years on TRT where my HCT seemed high and it corresponded to when I was only injecting IM 2x week and also upped my dose, even then I don't think it was that high. All that has changed from that one high reading is dosage and frequency. I wonder if possibly there could be a period where it rises as your body adapts and then goes back to baseline. I use a CPAP daily for sleep apnea. I also think that the values can move a few points just from being dehydrated. Neither my PCP or urologist who prescribes the TRT have had any concern with any of these numbers. I only became concerned with the July 23 reading from reading posts on forums like this and on Redditt where everyone makes it sound like you are going to stroke out without warning.

i just got a reading of 57.7 and was told that i needed to have a phlebotomy? does any one out there now what the fuck that is? Do i just need to go get my damn blood drawn? Anyone got insight into this matter?

Yes. It means you go get your damn blood drawn. Phlebotomy is a big word for that.

Were you hydrated at the time of your blood test? That would make a big difference.

Yep, and if you hydrate like a mofo for three days go get another hematocrit blood test. You'll likely be fine. There's ONE belle curve reference study that it seems all the docs are trained to read about this, and every time I ask one for more info on why, they don't seem to know. Early 2000s especially if we were using EQ we would dump blood donations on the regular. Problem with that at least for me, is my iron problem is now a bigger problem with shitty absorption. Others know more here than me on this one. Ever since I got right with staying hydrated , I don't even get close to 50

yes i was properly hydrated at the time of the test. Thanks man i appreciate the response i was trying to decide if i needed a damn doctor or a blood clinic.

So im guessing popping a 57.7 is high as shit or what these doctors seemed to have a freak out that it was crazy high.
 
if my hematocrit gets over 52ish i can physically feel it. it's like sleep won't do anything. can sleep 6 hrs, 8hrs, 12 hrs... all will feel like i slept 3 hrs. Makes me lethargic af. giving a double red makes me feel better instantly

Man that kinda answered a quesion without me even asking. Thanks for the assistance i got an appointment set up for today to go donate blood for me being that high how many times do you think i will have to donate in order to get my levels lowered?

itd probably drop you to 51-54%. id just start with a double red and then get a cbc later in the week. u may feel fine at those numbers. i usually dont.

Okay I didn’t even know about a double red. So thanks for pointing me in the right direction. I’ve dabbled with gear for a while but I’ve never really takin giving blood or doing labs seriously so I’m a bit ignorant on it all. One last question by you saying that it will drop me 51-54% are you saying it’s going to 20s on my levels?

no like down to 51-54ish end result. i expect around 1.5-2.5% per pint donated when i do it

U ever try supplementing nattokinase?
Is it from PED use or ?

i imagine im a lil susceptible to it as my dad gets altitude sickness. but my hct definitely hikes up on blasts. anadrol, deca, and high test tend to do it the worst. i think dhts dont really do much to it

Give nattokinase a a shot, it may not completely fix it but I would bet it makes a very noticeable difference.
When I dump blood at home it slow as fk without nattokinase but while on it I can notice it a lot thinner.
FYI- I am not promoting dumping blood at home but sometimes u get in a jam learning this shit & u gotta do what u gotta do.
 
 
Shit works!

JFC.
@MythicCajun did you not get any instructions or have any discussion after getting your readings. I assume the person who told you that you needed a phlebotomy was a doctor or a nurse?

I'm not necessarily dogging you for not knowing what a phlebotomy is but geez, some in the medical field don't really do their job. You should have been given specific instructions and been very clear on next steps.

u out here fixing all my ailments 😍

i'll give it a shot; when I had to dump a couple liters back in october (pulse was 126, red cross rejected me 💀) it was coming out like jelly

No phlebotomy but getting labs drawn in a few months. I will def be supplementing with nattokinase soon.

I have no anecdotal evidence yet that it helps lower by blood counts (tried supplementing last time before my blood draw) but I do know that it doesn't do anything to harm my other markers and my TomJoke-like google searches and forum reviews have definitely intrigued me enough that I gave it a shot and I'm going to try it again.

I remember you saying that. You really shouldn't have been rejected for that pulse. Perhaps someone there hates you. :unsure::Do_O
