Glutathione is a molecule that is produced naturally by the liver
The conditions we treat most frequently with BPC-157 in this category include Achilles tendinopathy, patellar tendinitis, lateral epicondylitis (tennis elbow), rotator cuff partial tears, partial ACL and MCL tears, and chronic ankle instability
In resting cells, GHK-Cu produces modest ERK1/2 activation supporting proliferative responses, while in inflammatory conditions, the peptide suppresses p38 and JNK activation, contributing to anti-inflammatory effects
In one case, a pharmacy used dietary supplement grade glutathione powder (intended for oral use) to make injectable drugs
For 5AR2, at those levels youd only reach ~1040% inhibition unless free Cu climbs into the tens of M
