That sucks, I think I have the same batch.
I got kisspeptin from a forum sponsor. The first two vials were fine and mixed okay with BAC water bought from the same place. Bought it late March 2026 and it arrived the first week of April so about three weeks ago. I keep everything in the fridge. Before mixing I let both the water and vial warm to room temp. Now every vial turns to gel in less than fifteen seconds after adding the water. The first two worked fine and I used them. The problem started yesterday. I emailed the seller and am waiting to hear back. Anyone know what could cause this?
