Primobolan side effects include that of cardiovascular strain and negative cholesterol changes, which is a side effect shared among all anabolic steroids. This involves the reduction of HDL (the good cholesterol) and increases of LDL (the bad cholesterol). The result of such changes is an increased risk of arteriosclerosis, and the degree to which these changes occur for the worse are usually dose-dependent (with higher doses increasing the negative changes and the risks). Other factors that affect these negative cholesterol changes are: duration of use, and route of administration. In terms of the route of administration, oral anabolic steroids are known as being the worst for their negative impacts on cholesterol in comparison to injectable anabolic steroids. This is where oral anabolic steroids hold a negative reputation for exhibiting a far worse negative impact on cholesterol in comparison to injectable anabolic steroids. This is due to the fact that the liver is essentially the body’s cholesterol processing and production center, and increased hepatotoxicity as a result of oral anabolic steroid use is associated with negative cholesterol changes.
Anabolic steroids can cause the development of acne. However, the extent to which it is experienced can be due to a number of varying factors, with the particular steroids and exact dosages used being primary. The skin´s sebaceous glands have a particularly high affinity to Dihydrotestosterone, which is an androgen the body naturally produces from testosterone via the enzyme 5-alpha Reductase. Increased sebaceous gland activity promotes oily skin which can combine with bacteria and dead skin (normal wear and tear) eventually causing pores to become clogged more quickly than the body can cleanse them. This of course, is preventable by using only particular steroids, cleansing the skin regularly, and perhaps using a topical anti-androgen.
In general it has been found that oral steroids are more likely to prove detrimental to cardiovascular health than injectable forms of non C-17 alkyl steroids. In this regard it is important to point out that estrogen is actually known to have a positive effect on cholesterol levels, enhancing HDL levels, and keeping LDL levels under control. It is when aromatase inhibitors in ancillary compounds come into play during the steroid cycles that the individual is at risk of cardio-vascular diseases owing to estrogen levels being subdued. Further, it has been seen that when the individual is committed to a healthy diet that supports desired cholesterol levels during the steroid cycle , the risk of cardiovascular disease arising from steroid use can be kept under control.
