Chemical Names: 4-androsten-3-one-17beta-ol 17beta-hydroxy-a ndrost-4-en-3-one
Estrogenic Activity: moderate
Testosterone cypionate is a slow-acting injectable ester of the basic male androgen testosterone. Testosterone is the principle anabolic hormone in men as well , and is the base of comparasion by which all other anabolic/androgenic steroids are adjudicated. Each testosterone injectables, testosterone cypionate is extremely preferred by athletes for its efficiency to promote strong gains in muscle mass and force.
Testosterone cypionate is obtainable in select human and veterinary drug marketplaces. structure and dose can diverge by country and manufacturer, but usually has 50 mg/ml, 100 mg/ml, 125 mg/ml, or 200 mg/ml of steroid solubled in oil.
Average dose: 250-1000 milligrams per week
The half-life of testosterone cypionate is about eight days after shot.
Side Effects (Estrogenic):
Raised estrogen levels could induce side effects such raised water retention, body fat gain or gynecomastia. Testosterone is regarded a moderate estrogenic steroid. An anti-estrogen such as clomiphen citrate or tamoxifen citrate may represent required prevention of estrogenic side effects.
Side Effects (Androgenic):
Testosterone is the basic male androgen, liable for maintaining secondary male sexual characteristic.
There`re androgenic side effects inclusive oily skin, acne, a body/facial hair growth.
Side Effects (Hepatotoxicity):
Testosterone doesn`t have hepatotoxic action; liver toxicity is improbable.
As this anabolic steroid is not very liver toxic, in-fact it is quite mild it can be used for extended periods of time; if you are not susceptible to DHT based side-effects you could reasonably supplement with Proviron the entire duration of your cycle. While it can be used for extended periods, as we will see dosing protocol can vary dramatically depending on the purpose for which it is used. If Proviron is being used simply as a quasi-anti-estrogen medication then a mere 25mg per day may be all you need but many will find 50mg to be needed if their cycle contains a high dosing of aromatizing steroids. For those who are supplementing for additional beneficial purposes higher doses may be needed; although 50mg will provide them solid effects a slightly higher bump may be needed. If you choose to use Proviron this is something you may need to play with as individual response will vary greatly. For the individual who supplements for the purpose of bridging, a rather common purpose of Proviron use, doses will necessarily be much higher, ranging from 100mg-150mg per day if the individual is going to obtain the desired effect and benefits.
While Primobolan is available as an oral, most females will find the injectable to be far more efficient for reasons we discussed above regarding the lack of C17-aa nature in this steroid. As for Winstrol, also available as an injectable in Winstrol Depot, in this case it doesn't matter which one you choose; however, as oral Winstrol is often available in a 10mg tab, the standard most common female dose, it only makes sense to go with the oral version. As both oral and injectable Winstrol are of a C17-aa nature, there is no safety benefit held by one and not the other. Then we come to Anavar, not only will this be the best of all oral steroids for females but the best anabolic androgenic steroid for females period. In many circles the Oxandrolone hormone that is Anavar has been labeled "The Girl Steroid" and for good reasons. This doesn't mean men cannot supplement; it simply means the hormone is more beneficial to women and as it is so well-tolerated it is more or less "The Queen" as it pertains to female anabolic steroid use.
An elevation in serum bilirubin level of more than 2 times ULN with associated transaminase rise is an ominous sign. This indicates severe hepatotoxicity and is likely to lead to mortality in 10% to 15% of patients, especially if the offending drug is not stopped ( Hy's Law ).   This is because it requires significant damage to the liver to impair bilirubin excretion, hence minor impairment (in the absence of biliary obstruction or Gilbert syndrome ) would not lead to jaundice. Other poor predictors of outcome are old age, female sex, high AST .  
As you can see from the references above, even the most toxic prescription oral steroid, Anadrol, has been deemed safe for use when dosed responsibly and when combined with proper monitoring. The above studies ranged from 16-30 weeks in length using doses of 100-150 mg per day, yet only the minority experienced an elevation in liver enzymes which was concerning to the medical researchers. If Anadrol can safely be used for extended periods of time under appropriate circumstances, then it seem reasonable to ascertain that less toxic steroids, such as Dianabol, can still be used for traditionally accepted 8-12 week cycles.
