Summary: Any effective drug or supplement has potential side-effects. Most of the gym whisperings and pop culture assumptions about steroids and their side effects are overblown at best. Usually they are out-and-out lies. These myths include “roid rage,” hair loss in men who aren’t already predisposed to baldness, and penile shrinkage. The side effects that have been reported from Test Propionate include slightly faster body and facial hair growth and an increased need to shave, slightly accelerated hair loss only in men who already are balding, and temporary mild acne even with low dosages. Please avoid this product.
c) Concentration of active product. This is probably the most prevalent cause of post-injection pain experienced by anabolic steroid users. This is most likely due to the demand for underground laboratories to produce more concentrated steroid preparations (high mg/ml of hormone) to reduce number and volumes of injections. One good example of this is the production of testosterone propionate by many different labs. If we look at the preparation of testosterone propionate by legitimate pharmaceutical companies, we see that the maximum concentration normally produced is 50mg/ml. Despite this, most underground labs today will produce multi-use vials of testosterone propionate that are at a minimum of 100mg/ml. Hormones that contain short esters on them (like acetate, propionate, phenylpropionate) have a much higher melting point and thus cannot be made as concentrated as those with longer esters (enanthate, decanoate, etc). Although testosterone propionate can be effectively made in standard amounts of solvents and oil to 100mg/ml without crashing out of this solution, once injected in the body, the solvents tend to leach out of the solution very quickly, being absorbed much quicker than the oil. This leaves behind oil and hormone in the muscle, and at the higher concentrations (which rely on solvents to not crash in solution) this will result in some of the hormone crashing out of solution to give crystals. These crystals cause significant muscular discomfort, and also can result in the recruitment of lymphocytes involved in inflammation thus the area around the crystals can get inflamed with a build up of blood cells. This takes time to dissipate and longer for the crystals to be absorbed into the body, which is why this type of pain and discomfort usually lasts for several days.
It should be noted however that there are certain carriers and solvents which allow for higher mg/ml preparations to be made that result in the reduction of pain. One solvent occasionally used is guaicol, which allows for more concentrated solutions to be produced and also acts as a slight analgesic or pain reliever at the site of injection. A more useful lipid carrier as an alternative to a normal oil carrier is ethyl oleate (EO). EO can be substituted for other carrier oils, and is a less viscous (thinner) carrier that also allows more of the hormone to be dissolved in it compared with other oils. The safety of EO for injections in humans is often questioned; however several different pharmaceutically produced injection products have been made that use EO as a carrier, most notably Farmak testosterone propionate. Furthermore, ethanol (alcohol) is converted to several products in the body when ingested, one being oleic acid. One potential issue with the use of EO however, is that a small percentage of users may experience an allergic-type reaction to its use, typified by a rash and some local discomfort, yet this is a more rare reaction to EO.
