Is Runescape always right?

Recently during my quest to get 70 crafting, I satrted to think of all the things i wanted to complete before becoming a member. One thing was acess to the magic guild. This would require level 63 or 64 magic because a wizards mind bomb drink raises your magic level by 2 or 3. After more research, runescape.com itself said that and i quote "Wizard's Mind Bomb
If your Magic level is 49 or below, the Mind Bomb will increase it temporarily by 2 levels. If your Magic level is above 49, your level will be boosted 3 levels temporarily. This item can be purchased from the inns at both Burthorpe and Falador." Here is the link-http://kbase.runescape.com/viewarticle.ws?article_id=2142. Is this true?? This link is from the real runescape website. I need to know. Can i trust it? Before i become a member i want acces to all the guilds(excluding heroes and legends). This is crucial if this is true. Level 63 magic will be miles easier then 64, so someone please tell me if i can trust the runescape websites claim. I need acces to the mage guild and this is the only concievable way, I also want to get into the guild via the drink. So please inform me(this message was directed to Stav and friends).

P.S. To get to 64 mage from 63 is over 2k more curse spells, doing that will take a while, 63 will be much easier, and i want 63, not 64. Also, next time Reasons for Runescape part 3 some out!

No, it is not used as a rest stop for someones finger between nose safaris, but it is used to allow humans to express a much larger range of lip motions than would otherwise be impossible, which enhances vocal and non-verbal communication.
