it DEFENITELY cause it, like the majority of steroids. Tren might be more dangerous due to its potency though.
But the problem is, the vast majority of people don't understand certain key indicators, due to our catastrophic corrupt deplorable medical system. We don't have access to real medical science, thats why the majority is misled and misinformed.
Cholesterol levels. Those are not just random numbers that go up or down just because. When your HDL goes down and your LDL goes up, people, due to our completely wrong allopathic medicine, see the number itself as the problem. As the disease. The number IS NOT the problem. The number is just an INDICATOR saying that something else is terribly wrong!!!
When a steroid like trenbolone causes the LDL to go up, that means, terrible damage is going on inside your body. Specifically, chronic inflammation. When chronic inflammation occurs in this case in the heart, the walls of the arteries literally begin to tear apart. At a microscopic levels of course. The body has its own mechanism of defense. Key amino acids and vitamins are used to repair and rebuild the tissue faster than it can completely burst. On top of that, the body use key antioxidants to combat the free radicals and prevent or decrease as much as it can oxidative damage. But there is a big problem. The vast majority of humans are severely low in essential nutrients. The right amount of vitamins, minerals, amino acids, are not present in the right quantities. Therefore, the body DOES NOT have the proper raw materials to efficiently combat the toxic effects of trenbolone. Let alone that an athlete needs multiple times more the essential nutrients than a sedentary human needs.
When the body does not have an efficient way to repair and rebuild the tissue on time, it has a secondary last resort measure. Use cholesterol and deposit it in the wall of the arteries in order to prevent internal bleeding. The liver produces more cholesterol and the Low density lipoprotein production goes up to carry the cholesterol to the areas being destroyed.
We can definitely say that when you use steroids, you are literally poisoning yourself just like with any prescription drug. There is no question that drugs are dangerous and can have catastrophic side effects. Its all a matter of weighing the benefits with the cons, and of course being as healthy as possible when it comes to nutrition. But that nutrition is not what you found in the locker room advises or even "generic" diets on boards. It is professional knowledge, assistance, monitoring, it is real medicine.
Lp(a) is a more specific indicator of heart damage, however no allopathic doctor ever test it. Why? ask pharmaceutical corporations.
NOTE: I am not a doctor nor trained in any medical field, I have just read, learn and researched extensively by myself because my dad passed away last year from heart disease. In an attempt to save him, for years I started investigating what was killing him.
