Vendor review for NextGen - I had sub-par results with their Tirz; Reta seems fine

[theexquisitehour]

I bought a 10-pack of Tirzepatide 30mg from NextGen in mid February. The packaging is really slick and nice-looking, but a few days into the first vial of NextGen's T30 I began to feel like it wasn't working very well. I upped my dosage, in case it was a plateau or an underfill, but didn't see improvement. At the same time I was also experiencing skin pains, torso, leg and foot aches, tiredness, dizziness, and various other random and intermittent ailments. Some of these can be diabetes symptoms, which would also suggest the pep wasn't having its usual effects, but by the middle of the second vial, I was sufficiently concerned that I decided to discontinue, and find another supplier. Their batch documentation and coa transparency isn't the greatest, so I've been meaning to send a vial in to Finnrick just to see what they say (can't afford $200+ for solo, self-funded testing). There was a big stink in March about grey vendor GLP-2 that turned out not to be Tirz at all, as well as vials with really high endotoxin levels, so with all these resellers sourcing ingredients and finished product from just a handful of Chinese manufacturers, it's not inconceivable that I got a bad batch. When I finally did recon my one vial of NextGen reta, it was fine. Did anyone else experience poor performance, or unusually severe allodynia with NG's late-winter/early spring T30?
