It seems that posters are getting confused between Sexual performance Enhancers, and treatments to slow or delay performance.
The products I mentioned above, available from Oxford Online Pharmacy are:
1. Vimdal, which is supplied in suitable containers for direct injection into the penis - an Enhancer containing Alprostadil, which is a similar drug to Viagra and with the same effects
2. Caverjet, also an injectable drug, similar to Vimdal, and containing the same properties and having similar effects
3. Vitaros, a performance enhancing cream to be rubbed into the penis, containing Alprostadil and with similar effects
4. Muse, which is in pellet form supplied with an applicator, one pellet being inserted directly into the tip of the penis where it is almost immediately absorbed. This also is an Alprostadil drug with similar effects
None of these drugs is a delay type drug
