Some users self-report it as similar to chewing on a copper coin

Simultaneously, the acidic pH that vitamin C requires (around 3.5) destabilizes copper peptides, which prefer neutral pH environments

Rapid onset of action Because the sublingual mucosa delivers peptides directly into the bloodstream, as explained in our how peptides work overview, onset of action is typically faster than oral administration and comparable to subcutaneous injection for some compounds

However, long-term human safety data is still being established

Additionally, BPC-157 restores gut barrier integrity, potentially reducing systemic inflammation that drives neuroinflammation linked to depression and anxiety
