What’s in an injectable?
There are usually three classes of components in an oil based injectable. These include a hormone, solvent/cosolvent, and preservative, like benzyl alcohol or chlorbutanol. The hormone is one of the various steroids available, and the main solvent is some type of oil, usually sesame. There may be cosolvents present as well, to aid in making the steroid more soluble. These cosolvents are the key to the “magic dissolving solution”. Since the “magic dissolving solution” prevents crystallization in depot, aka "the formation of steroid crystals in your butt", and hence, pain, we must ask what could prevent crystallization in depot? The obvious answer is a cosolvent.
However, the current cosolvent of choice, benzyl alcohol, has not done a very good job at giving pain free injection. The main reason being that benzyl alcohol is irritating at high concentrations, like above 10%, and that it is a water-soluble. One gram of benzyl alcohol is soluble in only 25mls of water (1). Thus, the benzyl alcohol will tend to leech out of the depot, and the steroid will become insoluble, and crystallize, and you will start walking like you have a corncob hidden in, well, you know Now if the cosolvent used was oil soluble and water insoluble, then we might have something. The cosolvent would stay in the oil, keeping the steroid in solution, and preventing crystallization. A well-known oil soluble cosolvent is benzyl benzoate. This is used in T-200 as a cosolvent, and is insoluble in water (1). If I had to guess, I would say this is the main ingredient in the “magic dissolving solution”, but really this article is about how to make your own high concentration steroids, and not what the ingredients are in any kit out there. A higher concentration of this combined with a reduction in oil could yield a pain-free injection with a higher mg/ml concentration.
Author’s Note: After writing the first draft of this article, a member of a discussion board I am on tried, independent of me, using 7mls of benzyl benzoate and 3 mls of benzyl alcohol, along with 10ml of oil to make a pain free 200mg/ml concentration of trenbolone acetate! Looks like it works!
