This site's own FAQ addresses this directly: there is no responsible universal timeline for any supplement. Results, if any, depend on the actual formula and the individual using it.
Rather than manufacturing a specific week-by-week promise, this site states plainly that it cannot offer a timeline without a confirmed formula — worth crediting that honesty over an invented, specific number of days or weeks.
Worth noting this site ties the timeline question directly back to its own unverified ingredient list — it cannot commit to a timeline for a formula it couldn't fully confirm in the first place.
