Characteristics:

Anabolicum Vister is innovative, and yet a dinosaur. Its technology is similar to that of andriol, in that its an attempt at a non-toxic oral anabolic. But its alas no longer in existence. It was discontinued some time ago now, and I doubt many people in the illegal circuit really noticed. It was successful in the same manner andriol was, it was indeed a non-toxic oral. It used a similar delivery system, but instead of a long ester, it used an ether attachment at the 17-alpha position to increase its lipophillicity. It was then sealed in a oil-filled capsule. The idea behind it being that the oil could be absorbed by the lymphatic system and thus by-pass the liver and avoid being broken down that way. That would reduce the need for a 17-alpha-alkylated structure that could damage the liver. The lymphatic system is a system of veins and arteries that ONLY absorb water. Or rather re-absorb water. When blood is delivered to tissues, only 85% of the fluid is recovered. If this process was allowed to continue, we would all swell up and explode. So the lymphatic system is called upon to remove the excess water and carry it to a place called the angulus venosus, where two large veins meet right before they empty out into the heart. But in the digestive tract, the lymphatic system also transports fats, which is why the lymph fluid in that area is particularly troubled. With a system such as that of Anabolicum Vister, the oil inside the cap (which is a fat) would easily be absorbed into the lymphatic system, avoid liver breakdown and be introduced directly into the bloodstream. Attaching the ether to make the molecule, in this case a boldenone molecule, more fat-loving allows it to stay suspended in the oil, and the whole should be absorbed and delivered. That's the theory behind a non-toxic oral.

But as was illustrated with andriol, the system didn't exactly work. It showed highly variable results, not just from person to person, but from day to day. Blood levels jumped up and down and in some people it seemed as if most of the time it didn't work at all, which basically meant instead of importing quinbolone (boldenone+ether) into the blood, you were feeding boldenone to the liver. Therefor effective doses of this steroid were quite high. If you know that each cap has 10 mg of quinbolone (which is maybe 8 mg of boldenone) and you need to take 100-200 mg to see a notable effect, then you know what you are dealing with. Especially since boldenone has a fairly high oral activity of its own, so 200 mg per day orally would do the trick regardless. In light of the cost and it being the only alternative, I think most people sucked it up and just took shots of boldenone instead. And so this nonetheless innovative steroid died a very unglorious death. Today very few people even really know it ever existed.

What is truly remarkable about this drug is its name. Quinbolone. It was given a new name while its basically just boldenone with an ether attached. Normally new names are only given when permanent structural changes are made, such as 17-alpha-alkylation. So its understandable that one would name a 17-alpha-alkylated boldenone methandrostenolone (D-bol) because the structural change is permanent, and all its metabolites will be altered in the same way and the drug will have different interactions with structures inside the organism. But not so for ethers and esters. They are usually broken off once they enter the blood leaving only the base steroid, in this case boldenone. I mean, Equipoise is still boldenone undecylenate, it isn't given a new name because the alteration is not structural or permanent. But Anabolicum Vister is called quinbolone because of its ether. Perhaps someone felt that boldenone cyclopentenyl was too hard to remember.

This is a particularly safe steroid. Androgenically boldenone is quite mild, and has little or no interaction with the 5AR enzyme1, so it doesn't form a more androgenic metabolite. Estrogenically it has only half the potency of testosterone, and unlike the other oral boldenone, methandrostenolone, it doesn't have a structural alteration that makes it form a more potent estrogen. So its particularly weak estrogenic as well. Since it's a non 17-alpha-alkylated oral, its in and out of the body in no time and no a serious threat to endocrine recovery after a cycle and the list goes on. So certainly the Parke Davis company succeeded in creating a safe anabolic steroid. Unfortunately it wasn't very effective. And definitely not cost-effective. This drug can now be considered completely extinct. Its no longer manufactured and hasn't been around for quite some time. Is it a shame ? Well, the bodybuilding community didn't feel it was, it barely even noticed it existed. Perhaps its discontinuance is a sign that no anabolic steroid can survive on the market without adequate interest from illicit users.

Stacking and Use:

As a particularly safe steroid in all aspects, quinbolone could easily be used with any other product, and unlike most orals, for extended periods of time. For perfomance enhancement I sincerely doubt anyone would think of using it by itself. Its somewhat weak, and having to take at least 10 caps per day didn't make it likely you would invest your funds in even more weak and expensive stuff. While 20-25 caps a day could easily mimic the effects of 300-400 mg/week of boldenone undecylenate injections, how many people do cycles of only 300-400 mg/week boldenone undecylenate ? Adding 10-15 caps per day to a cutting stack with trenbolone, winstrol and/or proviron for example could offer some benefit. Mild anti-catabolic properties and such, increased appetite and perhaps even some added vascularity, as these are properties of boldenone. For those seeking to gain mass however, quinbolone wasn't very useful.

What one needs to note about using this product (although since it no longer exists, this doesn't really matter) is that the daily doses need to be split up over the day. 3 or 4 doses. Unlike with 17-alpha-alkylated steroids which could exert influence way beyond their half-life time of 3-5 hours, quinbolone does not have this benefit, and its influence would be limited to its half-life time. Therefore, to keep levels somewhat constant, one needs to use multiple doses. With methandrostenolone, oxandrolone, stanozolol, oxymetholone, mesterolone, norethandrolone, methyltestosterone, etc, a single dose per day would suffice, but for things like Anabolicum Vister or Andriol, multiple doses are a must for proper effect.

The use of ancillary products with Anabolicum Vister is not required, due to its mild nature. Some Nolvadex or Clomid after the cycle may help to keep gains and bring back natural testosterone, but I wouldn't go digging deeper than that. Although because its almost essential to stack it for good results, you will probably need to addition other products to control the rest of your stack.
