@drgreghealth: Are peptides actually dangerous? I've been a functional medicine doctor for more than 25 years. Here's the honest answer. Peptides themselves aren't inherently dangerous. Some, like collagen peptides, have decades of safety data behind them. But the ones getting hyped online right now are sitting in a legal and regulatory gray zone. The FDA is still actively reviewing whether they can even be legally made, and that review is unresolved. Here's what most people miss: the real danger isn't in the molecule itself. It's the sourcing. Peptides bought online with no oversight come with no guarantee of purity, dosage, or even sterility. If you're going to explore peptide therapy, do it through a provider who can verify the source and monitor you. The question isn't, are peptides dangerous. It's, do you actually know what's in the vial? Curious about a specific one? Ask me below. Find the root. Heal the whole.

The FDA approved ones contribute to mental in balance.. it’s like you become detached from emotions that give you simple pleasure in life and that in itself seems dangerous

In reality these are micro dosed, mcg so if there were impurities what percentage of the peptide for say a 10mg vial would be dangerous? If the 10mg vial was 90 to 95% pure and it is reconstituted (diluted down) and then micro dosed how much of this micro dose would you need to take to be as dangerous as other chemical sources which we use every day? Cleaning chemicals, Petrochemicals, Heavy Metals, Asbestos, Arsenic in water, Smoking, Alcohol, Energy Drinks, Artificial Colour, Meat Preservatives, Micro Plastics in the Environment, Rubber for car tyres, General Air Pollution. Please don't spin bull dust

what's the level of checking the sourcing on supplements? what's the difference, seems reasonable to think supplements pose a higher risk.
