17α-Alkylated DHT derivatives cannot be potentiated via 5α-reductase however, as they are already 4,5α-reduced. AAS users tend to be unhappy with the portrayal of AAS as deadly in the media and in politics. According to one study, AAS users also distrust their physicians and in the sample 56% had not disclosed their AAS use to their physicians.

Non-17α-alkylated testosterone derivatives such as testosterone itself, DHT, and nandrolone all have poor oral bioavailability due to extensive first-pass hepatic metabolism and hence are not orally active. dragon pharma to this are AAS that are androgen precursors or prohormones, including dehydroepiandrosterone , androstenediol, androstenedione, boldione , bolandiol , bolandione , dienedione, mentabolan , and methoxydienone . AAS that are not orally active are used almost exclusively in the form of esters administered by intramuscular injection, which act as depots and function as long-acting prodrugs. Examples include testosterone, as testosterone cypionate, testosterone enanthate, and testosterone propionate, and nandrolone, as nandrolone phenylpropionate and nandrolone decanoate, among many others . An exception is the very long-chain ester testosterone undecanoate, which is orally active, albeit with only very low oral bioavailability (approximately 3%).

Misuse of anabolic steroids can cause a variety of side effects ranging from mild to harmful or even life-threatening. Most side effects are reversible if you stop taking the drugs, but others may be permanent. Technically called anabolic-androgenic steroids , steroids are a type of artificial testosterone.

This is called “stacking.” The athlete believes that different drugs will produce greater strength or muscle size than by using just one drug. What they don’t know, or choose to ignore, is the damage to the body that abuse of these drugs can cause. Strength improvements in the range of 5 to 20% of baseline strength, depending largely on the drugs and dose used as well as the administration period. Overall, the exercise where the most significant improvements were observed is the bench press.
