It seems legit idk I’m only started on .5 mg of Reta these past 2 weeks and I don’t know if it works or if it’s placebo or not lol

Found a great peptide source
Very good service and reasonable pricing for quality peptides. Hope to see more bioregulators available in the future. Very legit and knowledgeable staff.
