Sustanon (also known as Sustaretard and Tetrasterone) is a mixture of different testosterone esters, first developed and marketed by Organon as a hormone replacement therapy for insufficient endogenous testosterone secretion. At present, almost all mixtures of testosterone esters are identified with Sustanone.
Sustanon 250 contains four testosterone esters:
- phenyl propionate.
The esters in Sustanon are as follows:
- Propionate – considered one of the most popular forms of testosterone – a fast ester that has an almost immediate effect;
- Phenylpropionate / isocaproate: “middle” esters that start to act later than propionate. Isocaproate is needed to maintain optimal testosterone levels between propionate and decanoate. The half-life is 9 days. Phenylpropionate maintains optimal testosterone levels after complete rapid degradation of the ester.
- Decanoate is a “long” ester that is used in every steroid. Its half-life is 14 days. So it will be in the blood for a whole month. For this reason, experts recommend starting PCT a few weeks after the last dose of Sustanon.
Each form of testosterone that is part of Sustanon has a different rate of absorption, which allows it to maintain a consistently high level of anabolic hormones in the blood for one month. Frequent injections are not necessary, Sustanon is given only once every three weeks (for medical purposes). Some believe that Sustanon is a combined course in a bottle, but this is not entirely true because every component of the drug in the body only converts to testosterone.
The rate of absorption of each form is different, which explains the high efficacy of the drug. Maintains high testosterone levels throughout the month. Propionate enters the bloodstream first, followed by phenylpropionate, then isocaproate enters and decanoate is absorbed last.
The duration of action makes it possible to reduce the number of injections. This in no way affects the effectiveness of the mixture. By no means is it worse than drugs given alone. The only downside is the price. The mixture is usually more expensive.
Course of sustanon
- The Sustanon course is only recommended for men over the age of 21 to gain muscle mass, without contraindications to the use of anabolic steroids.
- The course of Sustanon lasts 6 weeks (only 5-6 injections per course). Gonadotropin is required for a longer period of time.
- The drug is injected once a week at a dose of 250-500 mg intramuscularly (it is desirable to inject Sustanon into the gluteal muscles).
- Start taking Nolvadex 10 mg daily starting the second week of the course. Stop taking Nolvadex 4 weeks after the last injection.
- 3 weeks after the last injection, start taking testosterone boosters for 3-4 weeks to resume your own testosterone production.
- For maximum effectiveness of the course, use a complex of sports nutrition for gaining muscle mass and follow a diet for gaining muscle mass.
Be sure to consult an expert before taking Sustanon.
Sustanon 250: Combined course
Sustanon can be combined with medicines such as:
- Nandrolone – for a set of muscle mass.
- Winstrol – For drying and relief.
The combination makes it possible to reduce the frequency of side effects and improve the effectiveness of the course.
The improved muscle mass set shows the use of the drug with nandrolone and relief and drying with Winstrol. A competent combination of steroids allows you to achieve a much better result than using each drug individually. This approach is not only effective but also minimizes the risk of adverse reactions.
Indications for acceptance
Sustanon is prescribed as part of substitution therapy for a number of pathological processes:
- delayed sexual development;
- Endocrine diseases that affect the functioning of the gonads;
- androgen deficiency;
- osteoporosis in women;
- Malignant neoplasms of mammary glands;
- Uterine fibers;
- endometriosis, etc.
The drug is actively used in sports:
- To increase resistance by stimulating the production of erythrocytes, which ensure rapid access of oxygen to the cells;
- To stimulate appetite during periods of energy stress;
- For fast muscle building;
- On anti-catabolism (slowing down the process of breaking down proteins in the body).
Important! The original Sustanon 250 is available only in glass ampoules, since, according to the storage conditions, the substance should only be in glass containers. Rubber caps are not allowed. The drug produced in vials has nothing to do with an anabolic steroid – it is 100% fake.
