Inquire bulk and customized quantity Welcome, Customer: Please do not inquire quote if your intended use is for a patient since our products are for research use and for chemical synthesis use, not for human use . For in-stock products, we listed price in the web page. You may inquire prices for which sizes were not listed. If no price is listed, this means the product is not in stock at the moment, which may be available via custom synthesis. For cost-effective reason, minimum order of 1g is requested (typically very expensive). The lead time is usually 2-4 months. Quote of less than 1g will not be provided. MedKoo may not offer quote for below reasons: (1) current available synthetic method appears to be extremely expensive which is obviously not affordable to most customers; (2) Key raw material to make the product is temporally not available; (3) DEA controlled substances; (4) the product is under patent protection in customer’s country.
