I emailed the popular supplier expressing concerns about ability to still obtain T3 and this was their response.
"Due to the fact that Uni Pharma T3 is almost non existent in pharmacies in Greece in last two months and the fact that we have it caused abnormal number of orders in recent weeks and it seems like half of the world is ordering from us at the moment. Because of several hundreds or orders we have to ship daily we physically cannot manage to honor our 48 hour shipping policy people are so used to, although we employed even more staff recently. So there are shipping queues and longer periods of waiting than usual. But we are doing our job properly as we always did and everybody are getting their orders eventually.
