I purchased 1 vial of GLP2 (10mg). It was a good price. I have been on this peptide for about 6 months. This was the first time with this company. Came in an unprofessional package (bubble wrapped in a $1 store container) that looked like it was packed in someone's garage. Reconstituted as usual. Took usual dose (2.5mg). Took on my usual schedule (every 6 days). Did not experience the usual outcome (lowered food noise, lowered hunger, slowed digestion). In fact it was like I took nothing at all. The quality and/or potency was not there. Will not purchase from them again.
