Conversely, it also increases bleeding risk, especially from gastric ulcer, and the net benefit will therefore largely depend on an individual’s cardiovascular disease (CVD) risk. Finally, some AAS users ‘treat’ their high hematocrit levels with low-dose aspirin (acetylsalicylic acid; 75–100 mg daily). A recent retrospective cohort study examined the risk of developing major adverse cardiovascular events (MACE) or VTE in 2 cohorts of hypogonadal men who received TRT and subsequently either developed erythrocytosis (hematocrit ≥52%) or did not (51). The HAARLEM study – a large prospective observational study in which users self-administered a mean AAS dosage of 898 mg weekly over a median duration of 13 weeks – showed similar results (46). In older men receiving the same dosage for the same duration, hemoglobin levels increase by 2.9 g/dL (37). Likewise, dutasteride had no effect on hemoglobin levels compared with placebo when used in conjunction with graded doses of testosterone enanthate up to 600 mg weekly (23).
Hypertension is an important risk factor for the development of cardiovascular disease and end organ damage, thereby causing significant morbidity and mortality (90–92). Prostate volume, as assessed by magnetic resonance imaging (MRI), remained unchanged in response to graded dosages up to 600 mg testosterone enanthate weekly for 20 weeks in healthy men (22). Clinical data in the literature remain limited to a single case report describing a 40-year old chronic AAS-using bodybuilder presenting with a prostate adenocarcinoma (87). Short study duration and the lack of sufficient statistical power make it impossible to draw firm conclusions. However, none of the trials to date have been designed to be sensitive enough to measure such an increase. While a severely flawed approach, the bioassay remains in use today, to some extent, in the quest for selective androgen receptor modulators (SARMs) (83, 84).
While this might indicate a true difference compared with testosterone, it might also be attributed to the relatively low dosages used and small samples sizes that make the research liable to type II statistical errors (a ‘false negative’). Similar changes are seen in men receiving supraphysiological dosages (200–600 mg weekly) of testosterone enanthate (15, 37, 118, 119), although not all trials show a statistically significant decrease (34, 120, 121). While not seen in every clinical trial, treatment of hypogonadal men with testosterone therapy reduces circulating HDL-cholesterol (117). Dyslipidemia, an imbalance in these lipoproteins, is recognized as an important risk factor for CVD, and treatment thereof forms one of the cornerstones of primary and secondary CVD prevention. The collective increase in these serum markers should thus be interpreted as a sign of liver damage, even in the presence of concomitant muscular exercise. The HAARLEM study also found no (sub)acute clinical signs of liver damage despite 67% of subjects reporting the use of oral AAS (39).
While direct data are lacking, these data suggest that 17α-methyltestosterone increases creatine biosynthesis and consequently the total creatine pool. Additionally, there is some evidence indicating that AAS use might increase endogenous creatine production. A larger increase in serum creatinine levels was observed in a small 4-week placebo-controlled trial with resistance-trained men randomized to 330 mg daily of the oral prohormone 3β-hydroxy-5α-androst-1-en-17-one (1-androsterone) or placebo (38).
These risks are further increased when athletes take steroids alongside other drugs, causing significantly more damage to their bodies. These effects include harmful changes in cholesterol levels (increased low-density lipoprotein and decreased high-density lipoprotein), acne, high blood pressure, liver damage (mainly with most oral AAS), and left ventricular hypertrophy. Anabolic steroids have a number of medical uses, but are also used by athletes to increase muscle size, strength, and performance. It is not known whether anabolic steroids are distributed into breast milk. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power. Stanozolol is a synthetic anabolic-androgenic steroid (AAS), which promotes cell growth (anabolism) and development/maintenance of masculine characteristics (androgenism).
Thirty-one men enrolled in the HAARLEM study were subjected to 3D echocardiography before, at the end, and a median of 8 months after the start of their self-administered AAS cycles (97). In hypertensive individuals, LV mass corrected for body surface area adds prognostic value for ischemic heart disease and heart failure in addition to established (SCORE) risk factors (218). However, they might compound the cardiovascular risk imposed by the other atherogenic effects of AAS, such as dyslipidemia, acting as potential CVD risk modifiers. AAS use can lead to concentric left ventricular hypertrophy, as signified by an increased LV posterior wall and interventricular septum thickness. Similar results were reported by Krieg et al. who observed a decreased Em/Am ratio on the basal part of the interventricular septum in a small group of AAS-using bodybuilders compared with steroid-free strength athletes and sedentary controls (216). AAS do not increase progesterone levels and only a select few demonstrate significant progesterone receptor activation (205).

It takes several months of testosterone treatment before hematocrit stabilizes, with one (uncontrolled) trial reporting a continuous increase in hematocrit up to 12 months in older men receiving testosterone (43). The effects of AAS on muscle mass and strength are at the root of this class of drugs’ popularity. More recent well-designed trials continued to provide further support for the potent muscle-building effects of AAS that had already been recognized by athletes for decades (15, 22, 35–38).
AAS users also self-medicate with these drugs to either prevent gynecomastia from developing or to reduce the size of existing gynecomastia. Such practice should be discouraged because it is illogical and produces possible side effects such as cardiac abnormalities or arrhythmia. As such, it seems reasonable to conclude that an absolute excess of estrogenic action causes the development of gynecomastia during candy96.fun AAS use, regardless of its relative action compared with androgens.
AAS users tend to research the drugs they are taking more than other controlled-substance users;citation needed however, the major sources consulted by steroid users include friends, non-medical handbooks, internet-based forums, blogs, and fitness magazines, which can provide questionable or inaccurate information. Another 2007 study found that 74% of non-medical AAS users had post-secondary degrees and more had completed college and fewer had failed to complete high school than is expected from the general populace. Studies in the United States have shown that AAS users tend to be mostly middle-class men with a median age of about 25 who are noncompetitive bodybuilders and non-athletes and use the drugs for cosmetic purposes. Ergogenic uses for AAS in sports, racing, and bodybuilding as performance-enhancing drugs are controversial because of their adverse effects and the potential to gain advantage in physical competitions. Objective evidence is conflicting and inconclusive as to whether these medications significantly increase athletic performance by increasing muscle strength. /is/ indicated in conditions such as chronic infections, extensive surgery, corticosteroid-induced myopathy, decubitus ulcers, burns, or severe trauma, which require reversal of catabolic processes or protein-sparing effects. - https://sigma-talenta.com/employer/dianabol-dosage-guide-how-much-dbol-should-you-take-per-day/
