The problem with certain peptides (the Eli Lilly patented ones like Tirzepatide and Retatrutide) is that when you carefully look at whats going on, you'll notice that they are recently filing lawsuits for anyone who mentions those words on their website, even med spa's and compounding pharmacies [0].
It is legal to sell research only peptides that are not FDA approved, but as soon you talk about efficacy and human use, you also become a target for the FDA warning letters. [1] [2] [3].
Anyone selling these peptides who are indexed by search engines face increase scrutiny immediately, especially if you're going to try to sell the patented ones, because then you're a Target of not just the FDA but also Eli Lilly... peptides are big business but it's big risk if you do it wrong.... Eli Lily wants people spending $1,000 per month to use these peptides.
I think the trick about selling peptides to people is to probably do it word of mouth, no indexing by google, no ads, double gated website with invite only structure.
There are some peptides which have been abandoned by the pharmaceutical industry before completing phase 3 trials and which can be sold through an FDA exception by compounding pharmacies.
That being said, there’s usually a reason they were abandoned by the pharmaceutical industry; they were ineffective or had a worse side effect profile compared to other drugs already in the pipeline. Good example of this is the “Barbie drug” melanotan II which was abandoned in favor of bremelanotide for treating hypoactive sexual desire because the latter targeted fewer receptors and was less likely to cause hyperpigmentation and other side effects.
Ultimately, most people should probably just stick to pharmaceuticals that have been FDA approved.
