Hi Laura,
This product is a sublingual spray so it is sprayed under the tongue. The instructions are found on this same product page under the tab Dosage Instructions.
We also have more detailed dosage instructions at our HGH-Pro educational site. We send a link to our detailed instructions to every customer with their order invoice. Here is that link:
Dosage Instructions For ProBLEN Products
I hope this has helped. If you have more questions please let me know.
Best Regards,
Lisa Wells, RN
