Oil Base q.s.

Drostanolone propionate is an injectsble anabolic steroid derived from dihydrotestosterone (DHT). Here, the DHT backbone has been rriodified with a 2-methyl group to increase its anabolic properties. making this agent significantly more effective at promoting the growth o‘ muscle tissue than its non-methylated parent. Drostanolone

propionate is described in product literature as a “steroid with powerful anabolic and anti-estrogenic properties,” and indeed does seem to share some of both properties.

Admittedly, however, its anabolic properties are more properly described as moderate. especially when placed in the context of other agents. The drug is most often used by dieting bodybuilders and athletes in speed e-sorts, where _it is highly favored for its ability to produce solid ircreases in lean muscle mass and strength, which are usually accomanied by reductions in body fat level and minimal side effects.

The US. Food and Drug Administration approved drostanolone propionate for the treatment of advanced inoperable breast cancerin postmenopausal women. This remained the principle clinical indication for the agent in all international markets as well. The prescribino literature reminds doctors and female patients that there is

considerably ess virilization with drostanolone propionate as compared to equal doses of testosterone propionate. Suggesting this was a much more comfortable alternative to testosterone iniections for the given audience, Still, the given dosage level (300 mg per week was relatively high, and the literature also reminds us that mild virilization symptoms still commonly occur, such as deepening of the voic, acne, facial hair growth, and enlargement of the clitoris. it also reports that marked virilization sometimes follows long-term  therapy.

How is Drostanolone Propionate supplied

Drostanolone propionate is no longer availab e as a prescription drug preparation. When produced. it was supplied in the form of 1 mL and  2mL ampules and 10 mL vials containing 50mg/ml or 100 mg/ml of steroid in oil.

Structural Characteristics of Drostanolone Propionate

Drostanolone. (also known as dromostanolone) is a modified form of dihydrotestosterone. it differs by the introduction of a methyl group at carbon-2 (alpha), which considerably increases the anabolic strength of the steroid by heightening its resistance to metabolism by the 3-hydroxysteroid dehydrogenase enzyme in skeletal muscle tissue. Drostanolone propionate is a modified form of drostanolone, where a carboxylic acid ester (propionic acid) has been attached to the 17-beta hydroxyl group.

Esterified steroids are less polar than free steroids, and are absorbed more  slowly from the area of  injection. Once in the bloodstream, the ester is removed to yield free (active) drosianolone. Esterified steroids are designed to prolong the window of therapeutic effect following administration. allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. The halflife of drostanolone propionate is approximately two days after injection.

Drostanolone Propionate Side Effects (Estrogenic)

Drostanolone is not aromatized by the body, and is not measurably estrogenic. An antiestrogen is not necessary when using this steroid, as gynecomastia should not be a concern ever among sensitive individuals. Since estrogen is the usual culprit with water retention, drostanolone instead produces a lean, quality look to the physique with no fear of excess subcutaneous fluid retention.This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns. As a non-aromatizable DHT derivative, drostanolone may impart an anti-eetrogenic affect, the drug competing with other (aromatizable) substrates. for binding to the aromatase enzyme.

Drostanolone Propionate Side Efifects (Androgenic)

Although classilfied as an anabolic steroid, androgenic side effects are still possible with this substance, especially with higher than normal therapeutic doses. This may include bouts. of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are warned of the potential

virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregtilarities, changes in skin texture, facial hair growth, and clitoral enlargement. Drostanolone is a steroid with relatively low androgenic activity relative to its tissue-building actions, making the threshold for strong androgenic side effects comparably higher than with more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone. Note that drostanolore is unaffected by the 5—alpha reductase enzyme, so its relative androgenicity is not affected by the concurrent use of finasteride or dutasteride.

Drostanolone Propionate Side Effects (Hepatotoxity)

Drostanolone is not c17-alpha alkylated, and not known to have hepatotoxic properties. Liver toxicity is unlikely.

Drostanolone Propionate Side Efiects (Cardiovascular) .

Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values. which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. iniectable), type of steroid (aromataable or non-aromatizable). ant: level of resistance to hepatic metabolism. Prostanolone should have a stronger negative effect on the hepatic management of cholesterol than testosterone or nandrolone due to its non-aromatizable nature, but a weaker impact than c-17 alpha alkylated steroids. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation. and support left ventricular hypertrophy. all potentially increasing the risk of cardiovascular disease and myocardial infarction.

To help reduce cardiovascular strain it is advised to maintain an active cardovascular exercise program ant: minimize the intake of saturated fats, cholesterol. and simple carbohydrates at all times during active  administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.

Drostanolone Propionate side Effects (Testosterone Suppression)

All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Vlfithout the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.

Drostanolone Propionate Administration (Men)

Drostanolone Propionate was not FDA approved for use in men. Prescribing guidelines are unavailable. For physique- or performance-enhancing purposes, this drug is usually injected three times per week. The total weekly dosage is typically 200-400 mg, which is taken for 612 weeks. This level of use is sufficient to provide measurable gains in lean muscle mass and strength.

Drostanolonc propionate is often combined with other steroids for an enhanced effect. Common stacks incude an iniectable anabolic such as which can provide notably enhanced muscle gains without excessive water retention. For mass gains, it is often combined with an iniectable testosterone. The result here can be solid muscle pain, with a lower level of water retention and other estrogenic side effects than if trese steroids were used alone (usually in higher doses). Masteron, however, is most commonly applied during  cutting phases of training.

Drostanolone Propionate Administration (Women)

The prescribing guidelines for Drolban recommended a dose of 100 mg giver three times per week. Therapy 3 given for a minimum of 8 to 12 weeks before an evaluation of its efficacy is made. If successful, the drug may be continued for as long as satisfactory results are obtained. Note that virilization symptoms were common at the recommended dosage. When used for physique-or performance-enhancing purposes, a dosage of 50 mg oer week is most common, taken for 4 to 6 weeks. Virilization symptoms are rare in doses of 100 mg per week or below. Note that due to the short-acting nature of the propionate ester, the total weekly dosage is usually subdivided into

smaller injections given once every second or third day.
