Frequently Asked Questions
Q: Why do peptides have “TFA salt”?
A: Trifluoroacetic acid stabilizes synthesis but may alter biological activity at nM concentrations.
Q: Can I import retatrutide for research?
A: Yes with proper documentation, but human administration remains illegal.
Q: Does buyretatrutide.shop sell research peptides?
A: No. We only provide information pending FDA approval.
