fda approved ghk-cu injectable Peptide Injection Before and After: What Changes Can You Expect? FDA scientists flag concerns with

Anterograde NO signaling promotes insertion of AMPA subunits at synapses undergoing LTP via guanylyl cyclase dependent protein kinase G (PKG) phosphorylation of its tail domain, while direct nitrosylation of multiple AMPA subunits and associated interaction partners also tend to have net LTP-promoting effects (Ivanova et al., 2020)

Most peptide solutions are essentially odorless, so any strong smell warrants investigation
