You can get sick from an overdose. Last year, there were 18,000 reported cases in the U.S. among users of brand-name pens.
Cases of endotoxins in batches from direct sellers in China are very rare. I've seen two or three come up over the past year, and people are still discussing them on the forum. The community handles these alerts very effectively. Just don't buy your peptides in a parking lot.
Ask an AI to compare reactions at the injection site, particularly when the solution is hypotonic, with reactions to endotoxins and live bacteria.
You’ll see many posts in this forum about immediate reactions, such as redness and itching, which last only a few tens of minutes. There are ways to address this, such as adding NaCl, diluting the solution further, using the right needle size, etc.
The reaction to endotoxins occurs after one or more hours and can last two or three days if the body is able to eliminate them. Sometimes there is a fever. Sometimes the symptoms worsen, requiring a doctor’s visit.
When I start a new batch, I do a test with a small amount. Reactions to endotoxins depend on how much was injected, your weight, and the health of your immune system. It’s important to know that during a diet, the human body goes into starvation mode, and the immune system becomes overactive (to ensure the survival of the species; the opposite happens in rats, which reproduce more than usual).
After three months, dozens of injections, and three different vendors, I haven't had any problems. It's not enough yet for me to draw any statistically significant conclusions, but it's encouraging, especially since it's consistent with what other users have reported.
