I have a question I'd like to run by the community. I was reconstituting a vial of MT2 when I noticed spots on the inside of the vial. I've been using peptides for years now, from a dozen or more different vendors, and never had a situation where the contents of the vial did not dissolve completely within ten or fifteen minutes, nor have I noticed anything that might be regarded as a contaminant stuck to the inside of a vial.
I've attached pictures with the larger spots circled. Keep in mind this is reconstituted, so there water drops as well. There were numerous smaller spots that do not show up in the photos. The spots appear to vary in color because some are above the water and some are below - I rolled the vial to try to catch both sides.
These pictures were taken roughly 24 hours after reconstitution. As I write this four days after that, the spots are still present.
This was part of an order from QSC. It was the second MT2 vial and noticed no issues with the first one. I've also used several vials of HCG, TB500, and BPC157 from that same order with no issues. I contacted QSC and sent the pictures you see below and, to be completely honest, I found the reply to be a little dismissive. I've also attached that email thread.
Basically, QSC claims that many peptides have solubility issues. However, I've never encountered that with any of the peptides I've ever used with any of the vendors I ever purchased from, and MT2 is one I've used for years. QSC also speculates that not enough BAC water was used for reconstitution and if I added more, the spots would magically dissolve. Again, I've been doing this for years, and 1ml of BAC has always been enough for 10mg of MT2, especially considering it's been DAYS since it was originally mixed. QSC offers no explanation for the (most likely) possibility that the vial wasn't clean and this is simply something stuck on the inside of the glass.
I know there are people here that like to bash QSC at every opportunity. I'm not looking for any of that. I've ordered from QSC several times and never had any issues. I was ready to place another order when this question popped up, and I'd like to get member feedback on these spots before I go further. Has anybody else had anything similar happen with peptides from QSC or anybody else? If so, what, if anything, did you end up doing?
