And this with a 3 day half life:
Once testosterone enters the bloodstream, a part of it is converted into estrogen by a process called aromatization. Increase in the level of estrogen is responsible for side effects like water-retention, gynecomastia or male breast enlargement, and even higher levels of blood pressure and cholesterol. Many side effects related to estrogen can be countered by the intake of supplements that inhibit aromatase. Changes in blood pressure and cholesterol levels can also be controlled through a balanced diet rich in omega fats, and cardiovascular exercise.
I will be doing something very similar and can offer some comments.

Testosterone androgenic side effects have more to do with the fact that Testosterone is converted into stronger and more potent androgen Dihydrotestosterone (DHT) by the 5-alpha reductase (5AR) enzyme.
Gynecomastia is the abnormal development of breast tissue in males. Enlargement of the breast tissue is associated with increased estrogen levels. This is countered by Selective Estrogen Receptor Modulators or Aromatase Inhibitors.
The potential for adverse reactions should also be considered when choosing a steroid to use, especially if AAS use is to be regularly repeated. For example, the listed oral medications present greater strain on the cardiovascular system, and are also liver toxic. For these reasons, the injectable medications listed are actually preferred for safety (testosterone most of all). Potential cosmetic side effects may also be taken into account. For example, men with a strong sensitivity to gynecomastia sometimes prefer non-estrogenic drugs such as methenolone, stanozolol, or oxandrolone. Individuals worried about hair loss, on the other hand, may isolate their use to predominantly anabolic drugs, such as nandrolone, methenolone, and oxandrolone. A detailed review of personal goals, health status, and potential side effects of each drug is advised before committing to any AAS regimen.
