Tolerability of intramuscular injections of testosterone ester in oil vehicle.

We undertook a prospective survey of the tolerability of deep i.m. injections of testosterone enanthate in a castor oil vehicle, the most widely used form of androgen replacement therapy. Over a period of 8 months, 26 men received 551 weekly injections into the gluteal, deltoid or thigh muscle and side-effects were recorded immediately and 1 week after each injection by the same nurse using a standardized questionnaire. Most injections caused no complaints [389/551, 70.6% (95% confidence interval 66.6-74.4%)] but minor local side-effects, mostly pain and bleeding, were common [162/551, 29.4% (25.6-33.4%)]; no serious side-effects were observed. Considering all side-effects, the gluteal site had fewer complaints and was less prone to bleeding but was painful more often than deltoid or thigh injection sites. The laterality of injection at any site had no significant effect on side-effects.
The only systemic side-effect was episodes of sudden-onset, non-productive cough associated with faintness following eight injections [1.5% (0.6-2.9%)] which we speculate may have been due to pulmonary oil microembolism. We conclude that, when administered by an experienced nurse, deep i.m. injection of testosterone enanthate in a castor oil vehicle is generally safe and well tolerated but causes relatively frequent minor side-effects, including pain and bleeding. An improved depot form of testosterone would be highly desirable for androgen replacement therapy and hormonal male contraception.

I have searched this board all over but "cough" is almost always associated with tren injections. And in my own experience i did some 40 injections with deca and test and never had a problem, but on my 2nd fina shot, i got the cough and some mild faintness. But in this study, they only used test enanthate and also experienced this side in rare cases. So? it might not be the fina itself but maybe the solution has the ability to penetrate veins more easily and therefore causes lung embolism. Isnt there a DMSO form of application with fina that is not possible with other AS? Are tren molecules smaller?
