What I would not buy (or buy again).  

There are a great many products that claim to contain pheromones.  Many claim to be the best or strongest.  There are also review sites that recommend bad products.  Often the most convincing sites sell bad products with all the money going into marketing a little into the product.  If you type "best pheromones" into google there are three paid for highlighted links at the top of the page, two of these are scams - they contain little or no pheromones and lots of exaggerated claims.

This is just a few of the many products that I would not buy (or buy again, as a few years ago I purchased two of these products before doing research - see photo at top and bottom of the page)   

Pherlure is the most heavily marketed pheromone, some people claim results but it is mostly bought by the inexperienced who fall for the wild claims. It claims it contains "di-dehydroepiandrosterone"  this does not exist.  Have a look at this site www.di-dehydroepiandrosterone.info You will have to cut and paste the link as I have read about them getting in touch with web hosts and trying to get sites taken down.

Androstenone Pheromone Concentrate APC claims to be the strongest on the market when it actually contains only a tiny amount, best avoided.

Pheromore Claims to be very strong but tests have been done disproving this claim by respected pheromone manufacturers.  Also got bad reports on forums.  This was about 4 years ago.

More to follow soon

ebay  -  the UK site is not good, Europe is probably worse, the US has a few good ones but lots and lots of bad ones.  Also with the feedback system people that know your username can see what you have purchased, not good.

Review sites -  Most so called review site are just scam sites promoting pherlure and nexus and other bad so called pheromones products
