Ive used your Bombyx ULTRA complex for the 2nd time and they are incredible, the result was everything you want from an ED medication only far far better and lasted much longer, the only side effect I had was I felt and looked a little flush after taking it however I had no headache and felt better than taking the more conventional meds on offer, I am a fit man of 72 and no vascular or heart conditions however my only anxiety is are they relatively safe ?? ……I hope so as I really enjoyed them and will be ordering some more soon, they tick boxes.
