Side effects

Also, like any type of testosterone, TEST COMP 250 is converted into estrogens. That’s why TEST COMP 250 provokes gynecomastia, fat deposition (in the beautiful half of humanity) and suppression of the production of personal testosterone. These manifestations from the use of this drug can be avoided if you use anti-estrogens – Altamofen (Tamoxifen Citrate) or Promifen (Clomiphene Citrate). By lowering the reproduction of endogenous testosterone, testicular atrophy is likely. This destructive effect of the drug can be avoided if the TEST COMP 250 course is not prolonged for more than 8 weeks and takes anti-estrogens. For long courses, Vitagon (gonadotropin) is required. In the body, testosterone is converted into dihydrotestosterone, which causes hypertrophy of the prostate, alopecia, acne. All of the above can be called androgenic side effects of TEST COMP 250. In addition, athletes often notice a rise in body temperature and an influenza-like condition. Like most of the steroids, TEST COMP 250 increases the level of harmful cholesterol in the blood (prevented by taking Omega-3 throughout the course of the drug). After the injection, infiltrates sometimes appear (seals or “bumps” in the buttocks or in another place of injection). Often infiltrates resolve within about 2-5 weeks.


The usual course duration is 6-8 weeks. Injections are made once a week with maintenance therapy, in a dosage of 250 to 500 mg. If it is necessary to prolong the course, doctors recommend including also gonadotropin. Also for the recruitment of muscle mass, the combination of Sustanon with Nandrolone has proved to be well, and Winstrol additionally promotes drying and relief set.
