Below you can find classic combined courses for high-quality muscle mass increasing, which are based on the basis of maximum safety and effectiveness.

The authors of the William Llewellyn's 10th edition book about Anabolics write that a combination of steroids is mostly often used by professional bodybuilders who are faced with a training plateau. In most cases, however, the combination allows you to achieve a cumulative effect (an increase of the total blood anabolic steroids concentration), which is necessary in further tolerance overcoming.

The rational combination involves a combination of high androgens contents substances  with predominantly anabolic effect drugs. The Anabolic category includes: boldenone, methenolone, nandrolone, oxandrolone and stanozolol. Androgen drugs include testosterone, oxymetholone. Methandrostenolone and Turinabol take an intermediate position and can serve as androgenic as well as anabolic component.

Who can use these steroid courses?

Slim-built men in the age over 25 years, who want to increase lean muscle mass, and don't have any contraindications to the anabolic steroids use.

To achieve maximum result each cycle should also include:

• Lean-muscle building diet plan - keep in mind that during one cycle you need to gain around 10 kg (2-3 kg would be lost later), so be sure to step on weight scales every three days, and control mass gain with the help of a diet plan.

If the mass gains are not fast enough, you need to increase calories intake and vice versa, otherwise you are just wasting time. The total amount of protein in the diet plan should be at least 2 g / kg body mass.

• Digestive enzymes
• Sports nutrition for mass increase
• Specialized training

Short courses for lean body mass increase

• Turinabol eliminates the testosterone androgenic effect, and also its combining helps to reduce the amount of stress put on the liver. It is used twice a day: in the morning and afternoon on an empty stomach.
• Testosterone propionate is a short ester, which allows to start anabolism quickly, and the course duration is significantly reduced. If you develop side effects, it is possible to stop taking the drug as soon as possible. Propionate has inconvenient application scheme and painful injections. It should be noted that propionate is often used during cutting courses with Winstrol; if you want to put on weight it is preferable to use enanthate. The differences of these esters are not in the effect mechanism, but in half-life duration and introduction convenience. Acceptable dose reduction is to 50 mg every other day.
• Aromatase inhibitors - are required even at low doses of testosterone, as the level of testosterone aromatization is high, so there is a need in the prevention of estrogen side effects (fluid accumulation, gynecomastia, suppression of the hypothalamic-pituitary-testes axis). Low doses of anastrozole are applied, which allows the body to maintain the required estrogen level, at the same time it improves the relief and speeds up recovery. Numerous reviews of athletes and skilled professionals confirm these facts. Ideally, the AI taking should be under specialized supervision (especially when estradiol level is high), and it should be noted that gynecomastia is often irreversible. An indirect sign of excessive estrogen suppression is reduced libido and erectile dysfunction, in this case, you should reduce the AI dose.
• Tamoxifen - is the post-cycle therapy base, which begins in 3-5 days after the final propionate injection. Tamoxifen can be replaced by less toxic clomiphene or toremifene.

Long-term courses for muscle mass increase

If the duration of the course is over 6-7 weeks, it increases the risk of irreversible testicular atrophy and incomplete recovery. This problem is solved by the use of gonadotropin. It should be noted that the maximum increase of athletic activities and muscle mass is observed only during the first 6-8 weeks and then it gradually reduces, along with certain side effects risk increase. Thus, there is no need to prolong the course for more than 10-12 weeks.

Turinabol is used as a front-loada during first 2-4 weeks to rapidly increase the anabolic steroids concentration in the blood until the enanthate absorption reaches high rates. Take the drug two times a day (morning, afternoon) on an empty stomach.

• Testosterone enanthate can be replaced by cypionate
• Aromatase inhibitors - anastrozole can be replaced by other similar drugs. Appropriateness of AI including is the same as in the previous course, it is desirable to take it under supervision.
• Chorionic gonadotropin has a set of controversial application protocols. However, recent studies have shown a clear need in the gonadotropin during long courses (more than 6 weeks). It allows to recover after the course much faster. Courses recommendations are based on the experience of andrology experts.

The course is similar to the previous one, with the replacement of Turinabol with more accessible methandrostenolone (it also used two times a day on an empty stomach).

Methandrostenolone is required as a front-loada for rapid increase of anabolic steroids concentration, because injectable forms begin to take effect only on the 2^nd or 3^rd week. Methandrostenolone can be replaced by Turinabol (30 mg daily). If it is necessary, you can skip taking front-loada, without any additional changes in the course.

Boldenone (Equipoise) can be replaced by Primobolan (200-400 mg per week).

Testosterone enanthate can be replaced by Cypionate, Sustanon or Omnadren.

In this case, aromatase inhibitors are not recommended by many experts, because testosterone dosage is low. However, it should be on hand for emergency use at the first signs of gynecomastia (itching and nipple swelling).
