Hey everyone - we've updated our Payments today, yay! We now accept Open Banking payments.

This is a good thing, as it offers considerably more security for you as the customer, and it means we can reduce prices even further.

We've had a small delay in postage during this past week to some customers due to a tech issue. Please rest assured everything is now resolved and back on track. Thank you for the patience from everyone who had problems.

Stock has landed! Note that any GH related peps are in scarce supply, we will therefore be limiting purchases to a maximum of a 4 week supply (based on medical average dosing) to keep things fair.
