question from a user

Every time I inject testosterone, my legs get really heavy and I got back aches. These symptom usually come on the day after injection and persist for several days. Ive tried different doses and protocols. Currently dosing 10mg a day for a total of 70mg a week of test C. Ive also tried various carrier oils. Noticed no difference.

AlphaMD's Answer

This is not a common side effect of TRT. However, there is some evidence that some men do experience muscle tightness with TRT. It is believed that this is due to increased activity at the neuromuscular junction resulting in increased muscle tone. In addition, testosterone does increase collagen deposition in the muscles, which can sometimes result in muscle stiffness. According to the research, this effect does slowly decrease with time. Either way, you would want to follow up with your doctor to discuss it further and rule out other potential causes.
