You just don't get it, there are counterfeit ED meds on the market here, even in some strategically located pharmacies. Just as you have fake women in Nana plaza.
This one was all over the place here, 9 or 10 years ago. https://www.tga.gov.au/news/safety-alerts/lilly-icos-cialis-20mg-tablets-lot-numbers-05668-and-ad47385-counterfeit. Bought a box in Pataya, wasn't impressed, a couple of month later bought another on Koh Chang, same <deleted>. Checked the boxes and then I saw that they had the lot number (05668), googled it and got many hits. These idiots just copied the box and didn't have any idea of what a lot number was. And no Tadalafil in those pills, just a weak dose of Sidenafil.
