Hi Gary,
Thank you for providing us with your feedback on this product.
We're sorry to hear that the level of effectiveness you have seen has changed over time and we're keen to learn more about your experience and provide advice on how you may get more consistent results.
To reassure you, we supply genuine prescription medication from the same reputable sources used by high-street pharmacies and as effectiveness depends on a range of individual factors, it can be common to see some variance in effectiveness but there are many treatments available to try.
Our support team have contacted you directly to assist you further accordingly and we look forward to hearing from you.
