Rating of nandrolone
Nandrolone was first synthesized in 1950, but the use he found only ten years later, in sports practice. In the 60s and 70s with nandrolone and methandrostenolone testosterone reigned in the big sports. I was no exception, of course, and bodybuilding. In the practice of bodybuilding place nandrolone – directly behind the undisputed leaders – testosterone and methandrostenolone, hardly any of anabolic steroids will soon encroach upon its position. Its structure is almost identical molecule nandrolone testosterone molecule. Except for one “small” detail – it does not have a methyl group in position 19. Hence the other name of nandrolone – 19-nortestosterone. Due to the elimination of one of the methyl group, nandrolone gained the ability where as better stabilize the androgen receptor (AR) that is, the existence of complex “Nandrolone + AP” over the lifetime of a similar complex with testosterone, and not just more, but once some sort of 2-3. And you know that the more time-ny androgen receptor is in an activated state, the more protein the cell can synthesize.
Nandrolone is not affected by aromatase. Despite this, he does convert to estrogen (specifically – estradiol), but in very small quantities: five times less than testosterone. At the same time it is known that nandrolone has a pronounced progestogenic activity, i.e., copies to a certain extent the action of another female hormone – progesterone. Despite the fact that the main activity of nandrolone and testosterone expressed in the same – namely, joining the androgen receptor within the cell and strengthening thus protein synthesis, these two steroids are synergistic; nandrolone not even in very large doses – of the order of 200-300 mg per week – to amplify the effect of testosterone. The combination of nandrolone with testosterone is superior to the combination of the well-known “deca-methane”;
Well, perhaps, with the entry finished, we now turn to the immediate consideration of the drugs.
Esters of nandrolone
We will consider only those of them that contain the active substance nandrolone decanoate or nandrolone phenylpropionate. But the general information about the other esters of this steroid also try to lead. And to begin with three interesting facts concerning not only nandrolone, but esters of anabolic steroids in general.
1. A “long-lived” esters are capable of providing a stable level of the active substance in blood plasma, although higher peak parameters inherent namely esters with less long chain ether.
2. In nandrolone decanoate actually slightly smaller than phenylpropionate. This is due to the fact that the ether chain decanoate has a higher molecular weight than the ester chain phenylpropionate; an equal number of greater nandrolone esters appears in either of them, wherein less “ballast”.
3.Of great importance is the concentration of active substance in solution – the higher it is, the drug appears to be more effective. Regarding nandrolone, the preparations with a concentration of 100 mg / ml are less effective than their four times “concentrated” counterparts 30-50%. Decanoate and phenylpropionate In addition, there are other nandrolone esters. In Italy and in France under the brand name “dinabolon” produced a rare broadcast of nandrolone – undecanoate. The ether undecanoate chain has one carbon atom more than the ether chain decanoate, and therefore the half-life of the drug was slightly longer – 9-12 days. Another drug, which is quite a rare visitor in our market – Laurabolin (nandrolone lo-rat). Laurabolin – injectable veterinary steroid producing mainly Mexican company Intervet and its Dutch affiliate. Nandrolone laurate – the active ingredient Laurabolin – has a more long-chain ethereal than undekaonat, and therefore has a longer half-life – 12-16 days. The rest of Laurabolin – this is the usual nandrolone, with all of this steroid advantages and disadvantages. And finally, the last of the “non-traditional” esters of nandrolone – geksiloksefinilpropionat (Anadur). This is the most “long-life” of the milestones of esters, period of his life is about 20-25 days. with all of this steroid advantages and disadvantages. And finally, the last of the “non-traditional” esters of nandrolone – geksiloksefinilpropionat (Anadur). This is the most “long-life” of the milestones of nandrolone esters, period of his life is about 20-25 days. with all of this steroid advantages and disadvantages.

nandrolone phenylpropionate
Phenylpropionate half-life hardly differs from the half-life propionate. Therefore, phenylpropionate injection frequency is the same as that of testosterone propionate – once in 2-3 days. Unfortunately, this broadcast of nandrolone are not as popular as its “big brother”, and for nothing, I must say. Whatever it was, found preparations containing the active substance nandrolone phenylpropionate harder. On this market they are only two.
