Neither needs to be a local injection. I am not sure who started the trend, but sub q meds dont just magically enter the tendon/ligament in the area of injection. It would be like trying AAS directly in a lagging muscle. It just doesnt work that way.700ugx7 days come on bro 4.9mg lol. I’ve never used TB500 does it need to be a local injection like BPC157. The closest I could get to elbow was IM deltoid. Didn’t really want to try and subq in forearm. I guess bicep could be used.
