Primo prices are overpriced..people just need to get it from India pharma but that's a different topic. So far I'm still on Q's HGH, hopefully they do get back on their feet and start producing it early 2026. The only products they produced were HGH anyways. They were simply resellers for everything else.
QSC didn't really "manufacture" rHGH. They produced the finished product by taking raw rHGH, adding mannitol, and lyophilizing it. This did give them a big price advantage over other vendors at the time.
Interestingly Tracy's chemist initially used a more complex excipient formula, but it lowered purity, so they switched to mannitol only.
Knowing what I know now, that excipient formula probobly kept rHGH more stable, but the short term purity test was more important for competing, so the product was downgraded to get a better number.
I read the process of a pharma company developing a new rHGH excipient formula, and they accept that some excipients will cause slight reduction in purity, with the tradeoff being much better stability after reconstitution.
Finally, a couple of sources have said there's only one supplier for rHGH bulk raws to all UGLs, GenSci's "Somatropin Industrial Park", a sprawling manufacturing complex that produces rHGH raw materials in huge quantities. This makes a lot more sense than some small operation trying to produce one of the most complex pharma molecules from a basement operation in a cost efficient way. Easy to slip a kilo, 3 million iu's, out of the back door of a place like this.
