Latest news (8th May 2014) on payment changes the requirement for prescriptions is on this update blog post.
Latest news (10th December 2014) on the closure of two of IHP’s sites is on this blog post.
Update 2, 7th May: Some people have received shipping confirmation from IHP following the advice here, so it appears it may be accurate. Update: Also see this email from IHP, which seems to contradict the information given over the phone. However…
Although phone calls and emails to the UK contact details listed on the IHP website have gone unreturned, someone has managed to contact with via their US web site. They have been told that the prescription required message is incorrect and was only intended for US customers, and that if you select the option to fax a prescription on the .biz site then they will ship it anyway as normal.
In addition, payment options have reappeared on the web site for UK shipping addresses and estrogen is no longer showing as all out of stock and/or discontinued.
I have not spoken to IHP personally, but this is all good news. I would be happy to hear from anyone who has received a shipping confirmation from IHP in the last 24 hours. (Receiving your order will, obviously, take a little longer!)
