So you would see this as a damaged product sold by the seller ?
I’d say I’ve never seen a Chinese seller do anything to replace “cloudy” rHGH. They always blame the end user and move on. Maybe it was ok when they shipped it, and it got stuck in a box near the roof of a cargo container in August hitting 150° f, not uncommon (I try to order peptides in cooler months). Maybe it had been sitting in a hot basement underneath a Beijing dry cleaner for a year before you got it. Who knows. This is why Pharma peptides are made by people in space suits and shipped in temp controlled conditions.
Toss it or filter it is my opinion.
At the very least try increasing dilution. Personally I’d filter it prior to use (remember, visible clarity is no assurance of lack of aggregation).
Just so you’re fully informed if you say fuck it and inject clouded solution, let me elaborate on the real world impact aggregates can have, and this is with pharma that wasn’t cloudy, and very likely has extremely low aggregates, unlike UGL:
None of us test for rHGH neutralizing antibodies, but if enough form they certainly affect rHGH effectiveness. The medial protocol has been to switch brands, (to one that hopefully has fewer aggregates the individual is sensitive to), and/or take a break.
Here you can see the level of inhibition (the amount of rHGH rendered ineffective by antibodies) in short stature children treated with rHGH and the steps taken to try and recover effectiveness.
And because endocrinologists know this matters while some bro-scientists will claim it doesn’t, here’s data from a brand of commercial pharma grade rHGH intended to illustrate the level of antibody production they produce vs competitors:
The biggest potential risk with peptides that resemble endogenous hormones like GH or GLP is the potential of developing immunity against your own naturally produced proteins. In other words, you develop immunity, and therefore reduced response, to your own naturally produced protein of the same compound.
Personally I don’t inject any unfiltered peptide to minimize immunogenicity risk.
