Post-Injection Pain - A Guide to intramuscular (IM) Injection Soreness
In this article I will review the main causes of localised muscular pain, tenderness and soreness that are experienced as a result of intramuscular IM injections. There are two main causative groups which injection pain can be categorised:. Within these two categories there are further sub-groups for causes of injection pain, and these will be discussed in further detail. Solvent concentration of substance.
The concentration and type of solvents used in the preparation of the substance to be injected will affect any pain and soreness that will be experienced post-injection.
Certain buffers and solvents used when injected in pure form give a fair amount of soreness. For example, some peptides are suspended in mM acetic acid, which when injected even in small amounts can give the user some discomfort. It is an important point to make that pain resulting from solvent concentrations used is most likely to commence quite soon after the injection, from a few minutes to a few hours maximum.
Pain that takes longer than this to develop is usually due to other factors discussed here. Another common solvent used as a preservative in anabolic steroid and other IM injection preparations, is benzyl alcohol BA.
At high concentrations, BA will cause injection pain in the vast majority of users. Many people claim that underground laboratories that make injectable anabolic steroids in a non-regulated manner use high BA percentages in their products such as testosterone propionate which is why users experience pain.
However, as explained here and in point 2 iii , the BA is unlikely to be the cause of pain. This is why it should be noted that in actual fact, many pharmaceutical preparations contain higher than expected amounts of BA in them.
However, many would here argue that Sustanon is a sore injection for many. For reasons discussed in part 2 iii , we may safely assume that the pain is more likely to occur due to the high concentration of these short esters, as opposed to merely high BA concentration.
Other solvents within the preparation apart from the ones outlined here can also contribute or cause injection pain; however the ones discussed are the most significant in the context of anabolic steroid preparations.
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.
Below is a list of common anabolic steroids and when prepared with common percentages of solvents and normal oil carriers not EO , what the maximum normal concentration that can be achieved before pain is experienced: In summary, there are various different causatives of IM pain post-injection, however the most prevalent is likely to be the concentration of hormone used in the preparation and secondly to a lesser extent, the concentration of solvents used.
However as outlined, with any injection this is an invasive procedure with regards to breaking the body's natural barriers, there is always a risk of soreness and discomfort.
