First of all why do you want to take a product which is not found scientifically proven values and follows unethical marketing practices?
The promotional website has a disclaimer in the bottom
"Note: This website is not run by or affiliated with USPLabs, LLC. To visit USP Labs' official website, please go to USPLabsDirect.com. Please note that none of the statements made on this website are approved or endorsed by USPlabs LLC. All statements are the sole property of this site's owners." The official web site of the USP labs cannot be found.
If the drug works through a mechanism claimed in the site (it is not believable, the reason I am not discussing here), it can be dangerous. Better avoided. Effexor
acts through neurotransmitters
serotonin and noradrenalin. So there could be possible adverse effects.
Better method for weight loss
is health diet and exercise. Exercise will lift your depression
and you may need less medicines if done regularly.
