There are any number of suppliers other than the sole sanctioned one. Search Alibaba. Assume you will pay a fraction of what you'd pay the sanctioned suppliers, but you will also have to run a sample via a LC-MS analysis to see that you are in fact getting what you think you are getting. This is all pretty easy to arrange, and works for just about any well known compound, peptide, etc.

If you are willing to do that, one would hope that you are also willing to (a) actually assess the results with the more robust quantified self metrics, rather than just hoping and feeling, as so many people do, and (b) take full responsibility for any harms or legal issues you cause yourself in the course of experimenting, as so few people do.

The detailed guides section here contains a couple of posts that walk through this process for a couple of other items, but the same general outline applies in exactly the same way:

I don't think the average person has access to a Mass Spec or Liquid Chromatography equipment.

$100-150 to run a sample through LC-MS via any one of dozens of small laboratory groups. Most are willing to explain things to a newcomer who is working his or her way through learning the ropes.

As a former chemist, I'd want to run a few more tests than just LC-MS. Like heavy metal levels and residual solvent levels.

Plenty of impurities don't show up in LC-MS.

I'm often either:

a) surprised that processes that seemed futuristic or industrial are available to the average person at a reasonable price

or

b) surprised that others are surprised

I operate a 4kW laser cutter set up to cut metal. Once new customers realise how much product the machine can put out in an hour they understand that it isn't an expensive service, and that it is in fact almost always cheaper to have an item laser cut rather than do it themselves using any of the tools they have in their workshop.

Anyone here know if anything like this is a available in the UK?
