Can you provide any substantiated evidence (or better yet, proof) that any sort of cream or oil has tangible, notable, and/or significant influence on gains, whether alone or in conjunction with penile exercises (like stretching) ?
The website you linked (which has been temporarily removed) looks like it was made 15 years ago and the product appears to have no regulation from what I could gather, hence the deletion. [Note to Readers* --> censorship is antithetical to this site in general, however, there are a multitude of scams and demonstrably unethical procedures & supplements (reviewed over decades of forum contributions & reviews) that on rare occasion compels me to remove from the site in order to prevent legitimizing literal snake oil. That said, if a strong case is made for its legitimacy, I'm open to any & all methods of (relatively) safe means of enlarging the penis on this forum.]
If you wish to share more about what you know, I may permit the link to be re-posted, but till such time, the term "snake oil" in American English implies a scam. I know English isn't your first language, and I'm sure that is not what you meant, but I can't help but look at the site and feel that it's nothing short of just unfounded claims. I know you're a Forum Veteran, so I know you mean well when sharing this content, so I ask of you to share with us more about the workings of this supplement for now before we start sharing "how to buy it." This is for everyone's benefit.
I hope you (and everyone else) have my understanding. Among my many responsibilities here, dispelling penis enlargement myths is one of them (e.g. how enlargement pills for example are notoriously scam-ridden).
