The latest news about oxytocin is that it helped regenerate muscle tissue in old mice. This is not so surprising; while most of the excitement about oxytocin is around its influence as a neurochemical on our emotions and thoughts, it's also a hormone that travels through the bloodstream and helps regulate many bodily functions.
A study led by Irini Conboy at UC Berkeley found that circulating oxytocin can help repair muscles, reducing the muscle wasting, or sarcopenia, that comes with aging. Daily subcutaneous injections of oxytocin allowed the older mice to repair muscle injuries as fast as the younger ones did.
The study was published June 10 in Nature.
I have an acquaintance who's struggled with fibromyalgia for most of his life. He's working with a naturopath who is able to prescribe drugs and is willing to help him experiment with treatments. He recently tried oxytocin injections. I asked him to write me about his experience, and here's what he says:
I injected 1 ml (10 units) of oxytocin subcutaneously, for a couple of months, as an experiment. I found that it raised my mood and gave me energy, which jibes with the article's conclusions. I stopped using it because oxytocin is only manufactured in small vials suitable for one-time use. For daily use, a bigger vial that can use a vial adapter would be required.
Oxytocin is quite expensive, and, unlike drugs like insulin which are packaged to be drawn out with a sterile needle over and over, the vials my friend got from the pharmacy were more than he needed for a single injection, but they could not be resealed.
People frequently ask me how to get oxytocin, and I always tell them to find a healthcare professional who will work with them, so my friend's experience is a good example of how the relationship with a medical provider can work. Unfortunately, it also points up a big issue with using oxytocin off-label.
