Feb 28, 2015 Want to talk about “thick blood” and now to prevent that. A few years ago I had a pulmonary embolism. For those who don’t know what it is – its blood clot to your lung. Not going to bore you with the details of what happened but talk more in general what I learned. Some of us has “thick blood” naturally. That means your hematocrit and hemoglobin is high. Mine is a bit high but usually (without AAS) stays in the normal range. Its probably genetic since many Scandinavians has higher levels. Never really had a problem or needed to watch it before is started AAS. AAS will increase both H&H and it’s a linear relationship between high H&H and embolisms. Make no mistake, embolisms are deadly. My friends mom died in the hospital from an embolism. A few things I learned. Monitor your blood. Make sure you do blood work while staying on for a while.. Your H&H will slowly increase. Donate blood as often as you can, its good for you. I make sure I do a phlebotomy every 2-3 months regardless of my H&H levels. Since I start doing that my numbers has been ok. When your blood gets thicker its a greater change for it to clot. Your heart has to pump harder to move the "sludge" around. If you are getting up in age use aspirin (81mg) every night. If you are on cycle use it also. I think the combo of high test with high estrogen is a bad combo for H&H. Control your estrogen. After my episode I saw an hematology (blood) doctor. He asked if I had to stay on the TRT. I said yes. He told me to make sure I monitor this and not take it likely. Got the long lecture about test and what happens, etc but didn’t try to make me get off. Trust me on this. Sitting in the ER was a huge eye opener for me. First time I realized I was not indestructible. The pain was excruciating and I was actually concerned I was going to die. If you can afford a bottle of test you can afford a CBC and other blood work. Don’t mess around here. Your corpse will look like shit pretty quick. Hopefully others can contribute to this thread and maybe we can come up with some guideline on how to do this safer. I hate to see anyone die or have major problems if it can be prevented by simply doing a phlebotomy.
