When T Nation first launched way back in 1998, getting your doctor to prescribe testosterone to you was tricky. Luckily most docs are up to speed these days on testosterone-replacement therapy (TRT). Heck, you can even find "low T" centers at your local strip mall and see commercials for testosterone in prime time.
Today you have the choice of injections, gels, creams, or pellets in treating low T. However, testosterone injections give you the most bang for your buck. And now, a new method may give you 20% extra bang for the very same buck. It's called subcutaneous or "subQ" injection.
If you've been on TRT for any length of time, it's likely your glutes are so scarred up from years of intramuscular (IM) injections that they're starting to resemble a piece of leftover gristle from the Sunday pot roast.
It's also quite likely those intramuscular injections are causing the occasional painful inflammatory response, in addition to needlessly spiking your estrogen levels. The safer, simpler, and perhaps even more effective way to administer testosterone is into the fatty layer just under the skin, otherwise known as a subcutaneous injection.
Dr. John Crisler, of the All Things Male Center for Health, has played a huge role in popularizing the subQ method.
