Hello Keith, Welcome to the forum 🙂 The reason you can not purchase the advanced products like P79 or TAL and TAH is because they are test mixes. They are for research and development and you need to be experienced with Androtics consumer line before you can purchase them. Androtics sells these pheromones at cost for accurate and detailed feedback. Studing and using pheromones successfully are two different things. Its best to start at the beginning and use consumer products instead of skipping right up to advanced. Here is a post that will explain it better. > [@Special Orders Not Accepted...](https://pheromonetalk.com/t/special-orders-not-accepted/4325): > > Until further notice for any customers who’ve been with us for less than 1 year, unless otherwise authorized by me. Aside from private and academic researchers, only those enthusiasts positing explicit, helpful feedback with dosage based mix details will be authorized. There has been an excessive amount of custom orders lately from newbies, and it’s starting to create an undesirable backlog that prohibits serious researchers and enthusiasts who depend on us. It only inhibits our own R&D. It tak… Jasmin and SteveO dont make people wait the year as it states in the post. Usually after you make a order or two and you leave your feedback on those consumer products they will let you start using the advanced products. The site is slowly changing and the advanced products will eventually be seperate from the consumers and at invitation only.
