The 3 Myths and Many Dangers of Anabolic Steroids

The term “pure” hormonal product implies a suspension of a substance that weider prime testosterone review dissolves in the body in a short period of time under the influence of certain factors. However, the suspension has a number of negative factors, in particular serious side effects on the body and rapid decay. A good alternative to the use of aqueous solutions, it is considered to be the appearance of hormonal preparations diluted in oil bases, as a result, substances with the conditional name - testosterone esters are obtained. Extracts from the seeds of wine grape varieties are used as an oil base.

How long do testosterone esters live?

 The principle of action of esters involves the slow activation of individual elements in the blood in contrast to drugs containing pure hormone. The unit here is considered to be the time spent on the half-life of the drug, when the volume of its content will be halved. The second criterion of measurement is the life cycle of a substance, or the existence of hormones in the blood before they are fully absorbed.

A life span is a period of time during which a hormone acts on the body or suppresses certain functions. This period is influenced by the dose of the injected substance. So if the half decay period of 100 buying testosterone gel online mg of the hormone testosterone propionate is two days, then the full life cycle will be at least 5-7 days.

Testosterone Esters - Basic Types

It is conditionally possible to differentiate drugs for substances with a short half-life (up to 2 days) and longer viability (up to 2 weeks). For use in bodybuilding pick up substances from the first group: testosterone propionate, enanthate, decanoate, cypionate and sustanon. The half-life of a substance can be determined based on its characteristics and properties, but the lifetime will be determined by the dose administered testosterone boosters for men and the properties of the substance. When prescribing the drug, one should pay attention mainly to the time of active stay of the hormone in the bloodstream.

Anabolic Steroids and Red Blood Cells

Testosterone Propionate

The period of half-decay of the hormonal drug is two days. In bodybuilding - this is the most popular drug that is in demand precisely because of the short period of its absorption by the body. It is included at all stages of the training course, initially propionate “accelerates” the process until the inclusion of “long esters”. At the end of the course, it is used for a quick exit, helping to quickly reduce the concentration of hormones in the blood.

Propionate is less prone to aromatization without filling muscles, it contributes to their drying with drawing of muscles, which is especially important when preparing for a competitive process. In the case of long esters, it is necessary to closely monitor the dosage of the drug, so it is often choose propionate. Among the disadvantages of using this drug should highlight the need for regular injections, testosterone prick will have with regularity every other day zinc and testosterone.

Testosterone Enantan and Cypionate

Enantan has a half-life of 10 days, respectively, for cypionate this period will be slightly longer and will be 12 days. By their properties and principle of action, these two ethers are very similar to each other. Differences are observed only at the molecular level. Most often, these esters are used in courses on the set of muscle mass. Conduct injection injection no more than once a week, the action of esters contributes to the retention of fluid in the body, therefore, it is preferable to apply them in courses on weight gain, but for the "drying" they will not be effective.

Testosterone Decanoate

 The half-decay time of a substance in the blood is 15 days, this is the longest period among all hormonal esters. Decanoate is not very popular among bodybuilders, it is mainly used low testosterone after vasectomy for a quick set of muscle mass or as one of the elements with the complex use of hormonal drugs.

Sustanon 250 (analogue Omnadren 250)

Testosterone and its esters Acetate caproate

Sustanon is a mix of four different essential testosterones. The composition of one milliliter of the active substance includes:

  • 30 mg of propionate;
  • 60 mg of phenylpropionate;
  • 60 mg of isocaproate;
  • 100 mg decanoate.

The combination of several ether testosterones at the same time does not allow a thorough designation of the half-decay time in Sustanone. Propionate is the lowest concentration of active ingredient in Sustanon, so it is advisable to prescribe it as an injection in the initial days of the course. Most bodybuilding enthusiasts arrive on the basis of the indicated how to stack winstrol and anavar formulas, start and end with propionate ether, and in the middle period apply sutanone. This regimen of hormonal steroids is similar to the use of enanthate or cypionate.

Anabolic Steroids: Facts, Effects and Health Risks

Sustanon has shown its effectiveness in full-fledged courses on building muscle mass, a greater effect is achieved due to the simultaneous use of several ethers. Another positive aspect is considered to be the uniform background of the distribution of hormones during the course.

Sustanon can be conditionally free to buy in a regular pharmacy, here it is better known as Omnadren 250. In most cases, pharmacy workers will require a prescription, but it is quite possible to find a place where they can sell without a prescription by going around several institutions. Pharmaceutical Sustanon distinguishes originality of manufacturing, here the chance of acquiring low-quality drug is minimal, which distinguishes it in comparison with the purchase of steroids from AU dealers.

Acetate and caproate and other esters

There are topical testosterone creams a number of other, less well-known ethers, the acquisition of which will cause certain difficulties, in particular because of their rare distribution. The half-life of these esters shows the following indicators:

  • Format. Just two hours, that is, the injection will need to be done immediately before exercise;
  • Acetate. Disintegrates to half the volume of its initial consistency in three days;
  • Phenylpropionate. The absorption of essential hormone occurs within five days;
  • Butyrate It can also be found in pharmacies, the half-life of about 6 days, can be used in combination with other esters;
  • Valerat and Hexanoat. Similar ethers with a half-life of 8 days, are quite rare;
  • Isocaproate An effective analogue of previous esters with a slight molecular difference, disintegrates to half of the active substance within 9 days;
  • Caproat It has a decomposition period similar to the previous drug (9 days), but differs in its composition;
  • Heptanoate. Half-life is 11 days;
  • Octanoate and Nonanoat. Analogs of esters with a long half-life of 12 and 13 days, respectively;
  • Undecanoate. Quite a rare form of testosterone with 17 days half-life.

In essence, the listed drugs have no significant differences from the esters considered in the initial part of the article. The only exception is the fairly “fast” testosterone format. The criteria for calculating the duration of the course and the time of the beginning and end of admission remain the same. Testosterone is the key basis of any course, respectively, is present in it, regardless of the type of reception and the intended purpose. The drugs are used under strict control of the athlete's health, often a course is prescribed simultaneously with maintenance therapy aimed at preserving the state testosterone booster really work of the liver and kidneys.
