Health Hazard SYMPTOMS | Symptoms of exposure to Oxymetholone may include cholestatic jaundice, hepatocellular neoplasms and peliosis hepatitis. Prepubertal exposure may cause phallic enlargement and increased frequency of erection. Postpubertal exposure may cause inhibition of testicular function, testicular atrophy, oligospermia, impotence, chronic priapism, epididymitis, bladder irritability, clitoral enlargement, menstrual irregularities, increased or decreased libido, excitation, insomnia, nausea, vomiting, diarrhea, leukemia, gynecomastia, deepening of the voice in women, hirsutism and male-pattern baldness in women, acne, edema, retention of serum electrolytes and decreased glucose tolerance. It may also cause higher risk of developing liver cell tumors. Other symptoms include abnormal liver function tests, salt and water retention and masculinization, particularly of the female fetus. |
Fire Hazard | Flash point data for Oxymetholone are not available. Oxymetholone is probably combustible. |

2. Oxymetholone / Anadrol Application:
Anadrol 50, also referred to as A50, is a powerful steroid that produces very noticeable weight
gains in a very short time. Unfortunately, it is also highly toxic in the liver and produces some
very unfavorable side effects, such as headaches, and bloating.
The gains from taking Anadrol 50 are very dramatic, but they tend to taper off quickly, which is
why it is often stacked at the beginning of a cycle as a kick-start to fast gains.
If this is the case we can only combat the estrogenic side effects of oxymetholone with estrogen
receptor antagonists such as Nolvadex or Clomid, and not with an aromatase inhibitor. The strong
anti-aromatase compounds such as Arimidex, Femara, or Aromasin would prove to be totally
useless with this steroid, as aromatase is not involved.
Anadrol 50 is also a very potent androgen. This factor tends to produce many pronounced, unwanted androgenic side effects. Oily skin, acne and body/facial hair growth can be seen very quickly with this drug. Many individuals respond with severe acne, often requiring medication to keep it under control. Some of these individuals find that Accutaine works well, which is a strong prescription drug that acts
on the sebaceous glands to reduce the release of oils. Those with a predisposition for male pattern baldness may want to stay away from Anadrol 50 completely, as this is certainly a possible side effect during therapy. And while some very adventurous female athletes do experiment with this compound,
it is much too androgenic to recommend. Irreversible virilization symptoms can be the result and may occur very quickly, possibly before you have a chance to take action.
It is interesting to note that Anadrol 50 does exhibit some tendency to convert to dihydrotestosterone, although this does not occur via the 5-alpha reductase enzyme (responsible for altering testosterone
to form DHT) as it is already a dihydrotestosterone based steroid. Aside from the added c-17 alpha alkylation, oxymetholone differs from DHT only by the addition of a 2-hydroxymethylene group. This grouping can be removed metabolically however, reducing oxymetholone to the potent androgen
l7alpha-methyl dihydrotestosterone (mesterolone; methyldihydrotestosterone). There is little doubt
that this biotransformation contributes at least at some level to the androgenic nature of this steroid, especially when we note that in its initial state Anadrol 50 has a notably low binding affinity for the androgen receptor. So although we have the option of using the reductase inhibitor finasteride
(Proscar) to reduce the androgenic nature of testosterone, it would be of no benefit with Anadrol 50
as this enzyme is not involved.
The old practice of slowly tapering off your dosage is totally ineffective at raising testosterone levels. Without ancillary drugs, run away cortisol levels will likely strip much of the muscle that was gained
during the cycle. If HCG and Clomid/Nolvadex are used properly, the person should be able to maintain
a considerable amount of new muscle mass. Before going off, some alternately choose to first switch
over to a milder injectable like Deca-Durabolin. This is in an effort to harden up the new mass, and can prove to be an effective practice. Although a drop of weight due to water loss is likely when making the switch, the end result should be the retention of more (quality) muscle mass with a less pronounced
crash. Remember ancillaries though, as testosterone production will not be rebounding during Deca therapy.
