Anatrofin (stenbolone acetate) is an injectable anabolic steroid that was developed in the 1960's in Germany. As a matter of fact, steroid guru Dan Duchaine considered anatrofin as one of his favorite steroids, and has written that if he had to pick one compound to run for the rest of his life, he would choose anatrofin. Unfortunately, this compound is very difficult to find today, and even though there were rumors of possibly only one company still producing it overseas, they were not confirmed. Nevertheless, there is always the possibility of this compound regaining its popularity, especially if the appeal for the lean muscle mass look will return to bodybuilding again.

Stenbolone acetate was introduced first in Germany by Schering, and two years later Syntex brought it to the United Kingdom, followed by Mexico, under the brand name Anatrofin. Eventually, it was brought to Spain under the Stenbolone name. Just like many anabolic androgenic steroids (AAS), anatrofin was used for its wonderful effects on anemia, and it was a very popular alternative to anadrol for this purpose because it had less side effects.
Background and Facts
Its name can lead us to logically put together that the acetate is the ester attached to this compound. However, the structure of this steroid has some unique properties. Anatrofin is derived from dihydrotestosterone (DHT) on a 1-testosterone framework with the addition of a 2-methyl group. Compared to testosterone, it is three times as anabolic with only a slightly higher androgenic effect.
From a structural standpoint, you could argue that anatrofin is similar to primobolan, with the only difference that primo has a 1-methyl group and not 2. This alteration is also seen if we compare masteron to proviron - both are very similar, but one is an oral and the other one is an injectable. Nevertheless, in this particular comparison, oddly enough, both compounds are injectables. Hence, the change might have more to do with the Germans' desire to come up with their own unique version of an anemia drug with very low side effects. No matter the reason, anatrofin was extremely popular in Europe among pro bodybuilders, who used it as a pre-contest agent because of its properties.
The side effects are automatically going to be low, as this compound does not aromatize into estrogen at all. Therefore, such estrogenic side effects as increased blood pressure, insomnia, water retention, and gyno will not occur. Interestingly enough, anatrofin does have slight androgenic traits, even without the aromatization of estrogen, leading to a possibility of having some acne, oily skin, and increased aggression. Thus, women should be wary of this steroid.
Obviously, all anabolic steroids will produce different results in different situations, but we can build on others' experiences to give an idea of what a compound will probably do for an athlete. Hence, most users report that you should not expect to gain massive size or strength with anatrofin because this compound will put on lean muscle mass without water weight gain.
We can speculate that Dan Duchaine loved this steroid because of its mild side effects combined with the ester attached. Thanks to its much shorter half life, you can expect anatrofin to give you primobolan like results in half the time.
PIP stands for post injection pain, which is a known problem to deal with when cycling anatrofin. The best way to combat this, is to mix the oil with another compound to dilute its bite. Furthermore, injecting small amounts per muscle each time can considerably help decrease the PIP. Unfortunately, this can become troublesome, since the dosage typically averages 500 milligrams (mg) per week for males. Thus, if you manage to get a hold of this stuff, expect to make a lot of painful injections.
As the reader can guess, with the acetate ester attached, the half life is only 3 days. This means that you will need to inject anatrofin much more often than the common ester of primobolan enanthate.
Remember, half life doesn't mean how long the compound stays in your system - it means the duration of time that will elapse, when half of the compound will be left. Having said this, with the acetate ester, either everyday or every other day injections are recommended.
Anatrofin dosages can range from 300 to 700 milligrams (mg) per week, and the normal cycle duration is 6-12 weeks. The short ester makes it possible to run a shorter cycle than you would usually do with primobolan enanthate. Female dosages are less than 75mg per week total.
