Дегидроэпиандростерон (ДГЭА) это гормон, который естественным образом встречается в организме и вырабатывается в основном надпочечниками. Он является предшественником нескольких других гормонов, включая тестостерон. Превращение ДГЭА в тестостерон является ключевым процессом, который влияет на различные физиологические функции как у мужчин, так и у женщин. Многие люди думают, что использование DHEA может заменить эффекты …

There are three FDA-approved testosterone injection formulations for use: ТК (Тест Ципионат),ТЭ (Тест Энантин), and TU (Test undecanoate). They are both testosterone and have different half-lives because they attach to ester chains of different lengths. TU has the longest ester chain, consisting of 11 carbon atoms, so it has the longest half-life and lasts longer after injection. TC and TE …

If we don’t know exactly what testosterone does, we can easily name a few, including muscle growth aand fat reduction. If you ask how testosterone works, most people probably don’t know. Сегодня, we will take a brief look at it. What’s the use of that, you might say? Who knows, maybe one day you’ll need it, maybe someone just needs …

When bodybuilders use Triiodothyronine T3, it is usually used during the cutting phase, which increases the basal metabolism, reduces fat and prevents muscle loss. Previously, T3 increased the basal metabolism and reduced fat, and today we will focus on how it can prevent muscle loss. In the cutting stage, it is mainly necessary to lose the fat stored during weight …

Natural testosterone refers to the testosterone naturally secrete by the body, which mainly produce by the testicles and regulate by positive and negative feedback of HPTA. Exogenous testosterone refers to testosterone introduced into the body from the outside, including testosterone replacement therapy (Trt) or anabolic steroids (Aas). Exogenous testosterone plays a role similar to natural testosterone, but it does not …

Since its discovery and in-depth study by biologists, testosterone has provided many new directions for human health and disease treatment. When use testosterone for medical purposes, it usually comes in the form of exogenous testosterone, which use to supplement or replace the body’s naturally testosterone and has an irreplaceable role. There are various forms of medical testosterone available, and This …

В организме человека, the thyroid hormones T3 and T4 exist simultaneously, one acting quickly and the other providing a slow and long-lasting effect. Rather than using one of them alone, the ideal idea for many BodyBuilders is to use them together. If use T3 and T4 together, how should we allocate the dose ratio of them? We can start …

When understanding the half-life of a testosterone derivative, we will propose that its half-life is relate to the length of the ester , and the longer the length of the ester chain, the longer the half-life of the corresponding compound. The half-life of testosterone is very short, only a few hours, and the testosterone after the addition of ester has …

Тестостерон является естественным мужским половым гормоном в организме человека. Он вырабатывается в основном в яичках у мужчин и в небольших количествах в яичниках и надпочечниках у женщин. Тестостерон представляет собой стероидное соединение с типичной стерановой структурой ядра, состоящей из трех углеродных пятичленных колец и одного углеродного четырехчленного кольца. It has the formula C19H28O2 and …

Usually use Triiodothyronine T3 to treat hypothyroidism ( the thyroid gland produce too little thyroid hormone ). This may be due to the disease itself, or it may be due to too little iodine intake or certain medications. Thyroid hormones are essential for the development of the body and mind, and hypothyroidism in childhood can lead to learning disabilities and growth …

The discovery and research of testosterone and its derivatives is of great significance, which opens the door of modern hormonology and greatly promotes the development of endocrinology, reproductive medicine and biology. The discovery of testosterone In the late 19th century, scientists studying the effects of castration on animals noticed that castrated animals lacked certain masculine traits and were associated with …

Тестостерон является мужским гормоном, однако, кроме мужчин, women also produce testosterone. Как происходит выработка тестостерона у мужчин и женщин? Testosterone production in men Men’s body produce testosterone mainly by the testicles , и гипоталамо-гипофизарно-тестикулярная ось (ХПГА) регулируют секрецию. Гипоталамус выделяет гонадотропин-рилизинг-гормон (ГнРГ) для стимуляции передней доли гипофиза к секреции гонадотропинов (ЛГ и ФСГ). Левая …
