It seems that benzyl alcohol is blaimed for pain at injection sites more often than any other drug or excipient non medicinal in parenternal preparations but the claims are completely unfounded and not backed up by anything in the scientific literature. My only explanation is that benzyl alcohol SOUNDS ominous so it must be responsible for pain...it couldn't possibly be the fact that most UG steroid preparations for injection these days contain unrealistically high concentrations of low solubility drugs like testosterone propionate and boldenone undecyclenate.
Benzyl alcohol is a topical aneastetic like its close relative phenol, BA is commonly used to lessen the pain associated with novocaine injections prior to the onset of action of the lidocaine. Here is a excerpt from a document from pubsmed:
MESH Definitions
Benzyl Alcohol
A colorless liquid with a sharp burning taste and slight odor. It is used as a local anesthetic and to reduce pain associated with LIDOCAINE injection. Also, it is used in the manufacture of other benzyl compounds, as a pharmaceutic aid, and in perfumery and flavoring
end quotation.
The use of benzyl benzoate and oils and solvents that greatly increase the solubility of the raw materials are much more likely to cause pain indirectly as many of them are quickly absorbed by the lymphatic system or surrounding tissues faster than the drugs or alternatively they are broken down or metabolized to their parts thus no longer acting as effective solvents or possibly the breakdown products could cause pain, main point being that this phenomena would result in undissolved raw materials=pain.
If you look at benzyl benzoate or ethyl oleate for instance a hydrolysis would yeild an organic acid , and hydrolysis is very common in the human body , the acid would have a ph much lower than physiological ph and that would also cause pain.
the strongest argument i think with respect to this topic is that legit pharmaceutical companies never used these witch doctor concoctions and potions of umpteen components to dissolve steroids and keep them dissolved in the bottle..becuase they know they don't stay dissolved in the body. they most commonly use 5% ba and one of sesame, poppyseed or grapeseed oil. some even go as high as 9% ba. they just dissolve what it will take comfortably and thats that, usually 50mgml for tp or bu and even sustanon by organon is 9%ba.
