Testosterone P 100mg/ml 2 ml c/u 5 vials Testosterone is one of the most commonly used substances within an anabolic cycle, as it is practically the basis on which most cycles are built. Within testosterone we can find different types, each with anabolic properties and characteristic side effects, as in all these types of substances, the more potent it is, the greater and more dangerous its side effects. One of the types we can find is testosterone propionate or testosterone propionate, within the testosterone scale can be placed at the midpoint, offering an acceptable increase in muscle mass and energy, without a great retention of liquids and with some side effects that while, should be taken into account, are not of the same intensity or magnitude as those that may appear by using testosterone enanthate or testosterone cypionate. Despite being a fairly balanced product, testosterone propionate is not a testosterone commonly used in anabolic cycles or in preparations for powerlifters. The clinical use of this substance is aimed at the treatment of patients with severe muscle loss due to complicated postoperatives or severe nutritional disorders. Also to treat hypogonadism (abnormal functioning of the testicles) in males and sexual dysfunction. Testosterone propionate is very fast absorption, and therefore its effects will be visible in a very short time, increasing energy, aggressiveness and appetite. Its duration in the body is 4 or 5 days, this makes it necessary to inject every 2 days if you want to maintain its effect during the cycle, instead, this fact makes it a more controllable substance being able to prevent side effects. Its use increases nitrogen retention in the muscles and a consequence of this is the better assimilation of the protein, in addition it also increases the amount of red blood cells and insulin growth factor (IGF-I) levels and, therefore, the level of growth hormone also increases. The retention of fluids that occurs with this type of testosterone is not a problem to consider since it does not come at all to the levels produced with enanthate or cypionate, therefore, the muscle mass obtained is of higher quality and definition. The duration of a cycle with this substance usually lasts between 8 and 16 weeks, and, although it is not a dangerous testosterone, the natural production of endogenous testosterone should be stimulated at the end of the cycle as the use of these substances inhibits this natural function of the testes. Having such a short life in the body makes it one of the most suitable testosterones to be used in women, provided that enough days are allowed between doses, otherwise virilization symptoms may appear. Testosterone Propionate Side Effects Although not of the most dangerous testosterones, the use of testosterone propionate may favor the appearance of certain undesirable effects that, in the event of falling into the error of using this substance, the necessary precautions should be taken to counteract and prevent them. Among the usual and less serious are the growth and strengthening of body hair, the appearance of acne in torso, back and limbs, and increased aggressiveness, a problem that can be more serious in people of an aggressive nature already in itself. The use of any testosterone can cause the baldness process to accelerate in those with a genetic predisposition to develop it. Although its androgenic level is lower than that of other testosterones, this does not exempt the risk of onset of gynecomastia, it is unlikely, but a suitable antiestrogenic such as Proviron or Novaldex should be used to avoid this unwanted effect. As mentioned above, when using a testosterone for a certain time, the testes stop naturally producing this hormone since the external contribution "accommodates" them so to speak not to produce, because, thanks to that contribution, the needs are covered. The problem arises when exogenous testosterone is stopped and the testes are not able to re-produce it, so substances such as Clomid should be used to favor this production after the end of the cycle, otherwise testicular atrophy will occur. It should be noted that when using testosterone increases cholesterol, therefore, people with hypertensive or high cholesterol should not use it. When using testosterone there is a relief in the joint pains that may be suffered, special care should be taken with this since it is more of an "anesthesia" than a recovery, the damage remains but not the sensation of pain, therefore, the joint will be subjected to greater efforts and burdens and can aggravate the injury. Although not one of the most dangerous products in the world of anabolics, the use of these substances is not recommended under any circumstances. Some of the side effects that may arise are irreversible and constitute a high price to pay for the use of anabolic products.
