Mackey MA, Conway AJ, Handelsman DJ. Tolerability of intramuscular injections of testosterone ester in oil vehicle. Hum Reprod. 1995;10(4):862-5.

ABSTRACT

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'm a little surprised at the bit about the delt\thigh being less painful than glute. This must be a VERY common misconception.

Its also odd that injection volume wasnt mentioned. At 2cc I would opt for glute over delt (or quad) 10/10 times.

The microembolism theory is pretty well common knowledge by now.

This study could be considered to shatter 2 common myths:

A) Glute is least painful site (at least with < 2cc)
B) The cough, so commonly called "tren cough", is due to the tren itself.

Imagine the day when pinning seems archaic and people are inhaling the latest and greatest designers. Inhalable insulin is already a reality.

i find that delts are the least painful spot by far. i put 2cc of 300mg/ml Tcyp there 2 days ago and if i didnt remember, i'd never know it. 100% painless. same shot in my glute from a week or so ago hurt (very dully) for probably 2 days. in the quad? forget about it. limped for 4 days.

The general consensus is that the best site for new/inexperienced people is the glute. Perhaps people should rethink this stance when giving advice. Not only is it harder to self inject there, but it may have no real benefit w/ normal volume injections. I see most people advising glute shots. Anyway, food for thought.

I do it for the kids....

Good find.
The pulmonary oil microembolism is what I believed caused the coughing so this is nice to read. However, it does seem that people tend to experience this much more frequently with tren than with other substances.

Glutes could possibly be a more forgiving for an unsteady hand than other areas.

Ventro glute is easy peasy lemon squeesey. :) More people should look into that site, IMO.

Deltoids are cake. Sometimes I get a painfull one that can ache for days.

I like glutes when my wife is administering as I can stay nice and relaxed. Minimal pain, if any.

I will never put a pin in my quad again, ever.
