Thioderon
(mepitiostane)
Thioderon Description:
Thioderon, a.k.a. mepitiostane, is a modified version of dihydrotestosterone (DHT), an anabolic steroid that was designed to treat testosterone deficiency in males. Thioderons possession of a rarely occurring modification causes it to differ from the usual c-17 alpha alkylated group (a modification that permits the drug to pass through the liver and into the bloodstream without being deactivated, thereby making it effective for oral administration). It replaces the 17aa group with an ether group attached to the 17-beta hydroxyl group (a modification that facilitates oral dosing via the lymphatic system) which serves as an alternate oral delivery method.

Thioderon is a moderately anabolic, mildly androgenic, non aromatizing steroid with anti-estrogenic properties. Based on the potency of this compound, you can expect it to produce measurable improvements in muscle size, strength, and performance making it the type of steroid that favors competition athletes. However, due to its limited manufacturing and rarely seen exportation, this steroid is not widely used by athletes.
Thioderon Form:
This Japan originating steroid comes in capsules containing 5 mg of steroid, and is exclusively manufactured in Japan, where it is available as a prescription medication.
Thioderon Indications/Purpose:
For bodybuilding/athletic purposes Thioderon increases testosterone levels which induce substantial increases in bodily shape and size, largely due to its ability to increase your number of muscle fibers. Androgens like testosterone also protect your hard earned muscle from the catabolic (muscle wasting) glucocorticoid hormones, by inhibiting their ability to send a message to muscle cells to release stored protein. Additionally, testosterone signals muscle cells to store more contractile protein (called actin and myosin) effectively countering the glucocorticoid hormones opposite release protein message. Furthermore, testosterone has the ability to increase erythropoiesis (red blood cell production) within your kidneys, and a higher red blood cell (RBC) count may improve endurance via better oxygenated blood. The presence of more RBCs has also been shown to improve recovery from strenuous physical activity.
The recommended dosage for Thioderon users is 20-50/day split in halves for twice daily administration (10-25/2x day) for 8-12 weeks, and 20 mg (10 mg/2x day) for 4-6 weeks for female administration, which is often enough to keep blood serum levels well above baseline with this particular drug. More specifically, Thioderons modest muscle and strength gains along with great muscular hardening, vascularity, and overall bodily definition are largely on par with those of the legendary cutting steroid Winstrol. Thus, Thioderon is a great latter cutting cycle addition which, compliments of its 17aa group removal, is not hepatotoxic.
Thioderon Side Effects:
There are hosts of possibly nasty, clinically-cited side effects for testosterone usage, many of which are greatly exaggerated by the media. However, the otherwise healthy bodybuilder has much less to worry about regarding side effects.
Thioderons very low aromatization means you can expect to be virtually free from estrogenic side effects (those due to increases in estrogen estradiol, prolactin, progesterone or progestin) which generally include increased water retention, body fat gain, and gynecomastia (actually due to an imbalance in the testosterone to estrogen ratio).
Androgenic side effects, those having to do with male sexual characteristics, occur due to elevated testosterone levels which are likely to produce oily skin, acne, body/facial hair growth, and testicular atrophy (temporary reduction in the size of your testicles). Androgen drug use of any kind is also known to accelerate balding, but only in men with a genetic predisposition for hair loss. In other words, if youre losing or going to lose your hair then testosterone supplementation can speed up the process, but it is never the primary cause of hair loss.
Synthetic testosterone and several other steroids, including nandrolones will shut down natural production altogether. A mere 100 mgs per week of either of these takes about 5-6 weeks to cause this shut down, 250-500 mgs shuts you down by the second week, and it takes roughly a month to return those testosterone levels to baseline. Although Thioderon may not be androgenic enough to promote shut down, it will definitely suppress natural testosterone production.
