Where to inject thymosin alpha-1?

As Zadaxin, thymosin alpha-1 is labeled for subcutaneous injection and not for intravenous use. That label does not name abdomen versus thigh versus arm. A research-chemical vial is not Zadaxin. The four general subcutaneous sites still apply: abdomen at least two inches from the navel, outer thigh, back of the upper arm, and upper outer buttock. Rotate sites. This is not a dose, a frequency, or a protocol. Full walkthrough at /injecting. Profile at /compounds/thymosin-alpha-1.
