Info: Drostanolone Enanthate, which should be more frequently known as Masteron Enanthate, is a long estered variant of Drostanolone. Drostanolone Enanthate is an anabolic androgenic steroid that first hit the market around 1970 under the trade name Masteron (which was Drostanolone Propionate,a short estered variant of Drostalonone) manufactured by Syntex.
Drostanolone is a Dihydrotestosterone (DHT) derivative, meaning it is a modified form of DHT itself. There are many anabolic steroids within the family of DHT derivatives, some of which are very well known and very popular (Oxandrolone/anavar, Stanozolol/winstrol, Methenolone/Primobolan and etc.).
The reason as to why DHT-derivatives are so popular and useful in the world of bodybuilding and athletics is due to the fact that they are incapable of conversion (aromatization) into Estrogen. DHT is not recognized as a proper substrate for the aromatase enzyme in the body, and therefore any hormone that is derived from DHT will assume these same qualities. The only strange exception to this rule would be Anadrol-50 (Oxymetholone), which expresses heavy estrogenic effects, but still does not actually aromatize. On the other hand, no estrogenic effects what so ever should be experienced with the use of Masteron Enanthate at any dosage used at all. The same goes for any other compounds that are in the DHT-derivative family (with the exception of Anadrol, of course)
Drostanolone carries relatively normal anabolic and androgenic activity; however, these ratings are somehow misleading. It’s important to remember DHT, the basis of Drostanolone , is five times more androgenic than testosterone with a much stronger binding affinity to the androgen receptor. This again promotes a harder look and can also enhance fat loss.
Drostanolone enanthate is one of the most underrated cutting steroids in the world.

Bodybuilders use this steroid to obtain hardness and sharpness of their muscles. It is commonly made the part of a pre-contest or an off-season program for adding new muscles while retaining existing muscles and keeping the body fat levels.
- Improves endurance
- Moderate increases in strength
- Faster regeneration
- Burn 5-7% of fat during cycle
- No water retention
- Muscle build-up
- Increases in collagen synthesis and bone mineral content.
- Increases in levels of IGF-1 and MGF hormones (which also promote muscle growth)
- Increases haemoglobin (red blood cell count)
- Anti-catabolic effect on muscle tissues by way of acting as an anti-glucocorticoid
Dose range and duration of use
- Common cycle length is 6-10 weeks
- Beginners: 200-400 mg/week
- Hobby: 400-600 mg/week
- Professional Range: 500-800 mg /week
- Women: 100-115/weekly
- Half-life: 4-6 days
- Detection time: 3-5 weeks
Masteron does not aromatize and it does not carry any progestin nature making estrogenic side effects impossible with this steroid. This means gynecomastia, bloating and water retention will not be concerns.
Due to its androgenic nature, Masteron can produce virilization symptoms in women. virilization symptoms can include body hair growth, a deepening of the vocal chords and clitoral enlargement.
Other possible side effects: loss of body hair and enlargement of the prostate gland, increased aggression, unsafe increases in cholesterol levels, high blood pressure, acne, and liver damage.
After cycle therapy
After cycle therapy start when 15-19 days past, when you done your last injection.Following the end of any cycle, a thorough and proper Post Cycle Therapy is always necessary, where Testosterone stimulating ancillary compounds such as Nolvadex and/or HCG should be utilized in order to facilitate the normalization of the HPTA (Hypothalamus-Pituitary-Testes-Axis) and endogenous Testosterone production as quickly as possible.
Drostanolone propionate iteself does not aromatize into Estrogen and thus does not require anti-estrogen protection throughout the cycle. However it is most commonly used in combination with a testosterone (which does require protection).
