Antipyretic Analgesic testosterone cypionate Stanozolol Tamoxifen
Estrogen activity, moderate progesterone activity, low common form of injection oil testosterone heptaneate brief introduction:
Testosterone heptaneate is a long-acting product of testosterone injection. After deep intramuscular injection, heptaneate releases testosterone into the blood for about 2 to 3 weeks. In order to maintain the normal physiological level of testosterone during androgen replacement therapy (TRT), it is usually necessary to inject testosterone heptaneate at least once every two weeks. In medical practice, most doctors prefer to inject testosterone heptaneate once a week. Like all testosterone injections, heptanoic acid testosterone heptanoic acid is favored by athletes because it can promote the strength and growth of muscle mass.
Testosterone heptaneate in the medical field:
Testosterone heptaneate is most commonly used in clinic to maintain the normal level of testosterone required by adult men with low androgen levels. Low androgen levels are characterized by low libido, weak body, small muscle mass and daily mental fatigue and lack of vitality. Testosterone heptanoate is also used to treat adolescent male testicular dysplasia and delayed puberty, and occasionally used as a secondary drug during female inoperable breast cancer. Testosterone heptaneate has also achieved great success as a male contraceptive. A group of studies on men in Thailand showed that the injection of 200 mg testosterone heptaneate per week would effectively reduce the sperm production of most men within three months, and this inhibition continued until the withdrawal of the drug. Up to now, testosterone heptaneate is still the most widely used testosterone hormone drug in the world.

Structural characteristics of testosterone heptaneate:
Among them, heptane acid has been connected to 17- β Hydroxyl. Esterified testosterone has less polarity than free testosterone and is absorbed more slowly from the injection area. Once in the blood, remove the ester and get free (active) testosterone. The esterified form of testosterone is designed to extend the window of treatment effect after administration. Compared with the injection of free (non esterified) steroids, the injection frequency of esterified steroid products can be less frequent. The half-life of testosterone heptate is about 8 days after injection.
Side effects of testosterone heptaneate: (estrogen side effects)
Testosterone is easily aromatized in the body, and then converted into estradiol (estrogen). Aromatase (estrogen synthetase) is responsible for this metabolism of testosterone. Elevated estrogen levels can cause some side effects, such as body water storage, increased body fat and breast development in men (bitch milk). Testosterone is considered to be a moderate estrogen steroid. Some anti-estrogen drugs, such as clomiphene or tamoxifen, are necessary to prevent the side effects of estrogen elevation. Aromatase inhibitors such as Arimidex can also be used instead, which can control estrogen more effectively by blocking the synthesis of estrogen. However, compared with anti-estrogen drugs, aromatase inhibitors are more expensive and have a negative impact on blood lipids. The effect of estrogen side effects is generally determined by the use of doses. Higher doses of testosterone (higher than the normal treatment level) need to use anti-estrogen or aromatase inhibitors at the same time to inhibit the body's estrogen level. The reduction of water storage, body dryness and muscle clarity caused by higher doses of testosterone is common, so this testosterone heptaneate is generally considered not to be added to the preparation or fat reduction cycle. Its moderate estrogenicity makes it more suitable for the non-season muscle increase period. The water storage feature is more conducive to supporting the training intensity and muscle size in the non-season season, and to promoting a stronger anabolic environment.

Dosage of testosterone heptaneate:
For the treatment of androgen deficiency in medical treatment, the prescription guidelines for testosterone heptaneate require a dose of 50-100 mg every 2 to 4 weeks, although the activity in the body lasts a long time. However, in the field of bodybuilding, the commonly used dose for muscle growth or improving exercise performance is 200-600 mg per week, usually used for 6-12 weeks. This level is enough to make most people notice the significant increase in muscle size and strength. Testosterone heptaneate is usually used in off-season muscle augmentation. In off-season, the water storage brought by testosterone heptaneate is irrelevant, and users are more concerned about muscle growth than state. Some athletes also use it as the basic testosterone level maintenance in the preparation cycle, but usually use a lower dose (100-200mg per week) and aromatase inhibitor to control the estrogen level. Testosterone heptaneate is a very effective anabolic drug. Even if used alone, the effect will be very good. Most people use it in combination with other anabolic/androgen steroids to obtain stronger effects.
