Boldenone is an oil-based anabolic steroid injection, to which the undecylenate ester is attached due to a slower rate of release and half-life. It is a derivative of testosterone, which maintains its anabolic strength, but shows less androgenic strength compared to testosterone. Boldenone is particularly a veterinary product, originally designed for use in animals. Boldenone gained popularity among bodybuilders and athletes as a less androgenic form of testosterone with less estrogenic activity than testosterone. Boldenone undecylenate was accidentally developed while trying to create a long-acting injectable form of methandrostanolone. This is the fact that clearly justifies why Boldenone is very wrongly linked to the chemical affinity of Nandrolone. It is actually an injectable form of methandrostanolone without a CH3 group. Provides slow, quality and sustainable gains without excessive water retention. An increase in the effect of the pump and an excessive 'veiny appearance' that provides a low percentage of fat are also mentioned. This AAS is used as in the diet, as well as volume. The most commonly used form is the injection together with the ester undecylenate, the least frequent use is its propionate form and especially because it causes significant pain on the second day after application, along with the influenza A condition that is often so unpleasant that it is almost impossible to finish the training It not only increases protein synthesis, but also the level of erythropoietin, which increases the number of red blood cells and the effect of the pump during training.With the use of this preparation, increased appetite and glycogen levels are often mentioned as well. Regarding side effects, it belongs to the group of highly underestimated anabolic steroids, although it is not an extreme, there is something to consider since it was a very little used AAS for human use in its injectable form. SIDE EFFECTS Side effects resulting from the action of estrogens are mild in nature. However, it aromatizes and with increasing dosage the aromatization occurs more and more. But it can be said that the estrogenic activity of this substance is so low, that it brings more benefits in the context of enhancing anabolic effects than disadvantages. Androgenic side effects are still lower than estrogenic ones. Its conversion in the body to dihydroboldenone is completely negligible (dihydroboldenone is 5 times more anabolic than testosterone), so hair loss and acne are rarely mentioned. It reduces endogenous testosterone (natural body), but it can be said that only slightly, but with increasing dosage and duration of creation of testosterone use will decrease significantly. Increased blood pressure is another side effect, which tends to manifest itself especially with prolonged use. Another common side effect is excessive stress on the kidneys and irregular heartbeat, all due to excessively high levels of red blood cells. This increased level of red blood cells can manifest in shortness of breath during daily activities, which also reduces the intensity of training. DOSAGE Boldenone undecylenate should be administered every 5-7 days.It is usually used frond-loading style, if used in constant doses its effects are felt only after a few weeks, frond-loading style use, Noticeable effects may be achieved a little earlier. The effect remains in the body for 3 to 4 weeks. The most important thing is not to forget the fact that it is necessary to take boldenone for a period of 8-16 weeks. For beginners, a sufficient amount is in the range of 300-500 mg per week. Intermediate users achieve huge gains and progress in the 500-700mg per week range, with no need to use doses higher than 500mg per week, especially when combined with other anabolic steroids. Experienced users do not normally use very high doses such as anabolic steroid such as Boldenone, but advanced users doses are in the range of 700 – 1000mg per week. Material balances are maintained in the body for 4-6 months.
