As for TB-500, there are no published peer-reviewed trials in humans
Supplier qualification criteria have been revised to include stricter compliance benchmarks
For example, researchers examining the impact of these two peptides on brain health and cognitive performance may prefer to use nasal spray due to quick absorption and rapid response
