I have received your message and am replying here again on the issue so that more people can see it and hopefully it will help more people
First of all Potassium Carbonate is usually too much but 856g is too much, if the subsequent cleaning is not thorough enough it may affect the purity of the product, so we suggest you use 750g.
For 5-bromo-1-pentene, we suggest you to use 550g.
For the reaction time we suggest about 5 hours, but here we remind you to use powdered potassium carbonate, all suppliers who do not remind this before or provide crystal potassium carbonate are considered extremely unprofessional, please pay special attention to this detail.
For MDMB-CHMINACA/FUBINACA etc. we can supply precursors and related materials, provide instructions and assistance, and guarantee 100% success according to our promises.
Once again, don't just worry about the price, the quality of the precursor varies, we only provide the correct precursor with high purity, so the manufacturing cost will be higher, but we guarantee that the product you produce with our precursor will have the strongest effect, as far as the profit margins are concerned, I think it's better to spend $200 more to get a better precursor than to get an inferior one, a good product will get you more customers and more profit returns, we are not just about price. A good product will get you more customers and more profit, so we always believe that quality comes first, Sellers who offer low-priced, inefficient precursors will be eliminated from this market sooner or later
