Libriol is a blended injectable veterinary steroid preparation that is made by RWR (formerly a subsidiary of Nature Vet) in Australia.This is primarily an anabolic agent, containing a mixture nandrolone phenylpropionate and methandriol dipropionate. These two steroids are present in a concentration of 30mg/mL and 45mg/mL respectively, equating to a total steroid concentration of 75mg/mL. Both agents in this product are considered pretty mild in terms of side effects and overall effectiveness, and are looked at more so for their abilities to promote lean tissue gain than bulk mass (for a more comprehensive discussion on the individual components, please refer to their respective drug profiles). This makes Libriol a great lean tissue builder, but far removed from drugs like testosterone, Dianabol, or Anadrol in its ability to pack on sheer weight, size, and strength.
Since both of the steroids present in Libriol are modified with fast acting esters, blood hormone concentrations will not stay steady for very long after each injection. It would therefore be most effective to inject this drug at least twice per week, three times if you want to be meticulous about dosing.The total concentration of steroid is not remarkably high in this product either, so you better get used to quite a bit of injecting if you plan on using this as the sole drug in your next cycle. A weekly total dose of 6cc would probably be most appropriate (adding up to 450mg), perhaps even 8cc (600mg).This would mean two to three injections would be given each and every week, with a full 3cc's of oil volume needed almost each time (not too comfortable). For this reason most use a bottle or two of Libriol to add some potency to an already existing stack, rather than relying on this drug alone.
In 2005, RWR officially replaced Libriol with RWR 4 Fillies. This is simply a new trade name for the same original formulation. RWR 4 Fillies is currently sold only in 10mL multi-dose vials, which means that you are getting only 750mg of steroid in total in each.This is not a lot of steroid, and likely the vial will not be dirt-cheap to purchase either.
As a result, it is probably not one of the most cost effective steroids available. Plus, its packaging is pretty simple, and well suited for counterfeiting (fakes have been identified, so be warned). This means that any abundance, especially in the U.S. where Aussie steroids do not circulate very often, should be looked at with extreme suspicion. Aside from the above concerns, there is little else to criticize about this product. It is a very simple blend of two effective and mild anabolic agents, which do exactly what you would expect them to do (provide fair gains with minimal side effects). If you have a real bottle, and you paid a fair price for it, I suspect you will find it is a very good addition to your next cycle.
