Hey there, well I was told by a friend of mine who said there is a potion (not ther serum 207) that only costs 5m to level herblore from 63-70. I was wondering if anyone knew what this potion was or if there is a faster way.

You can sort by best GP/XP.

 

According to RS Wiki, the cheapest potion to make right now that is worth the effort and able to buy/sell is strength potions at -10.64. Good luck.

 

Potions and herbs are bouncing around a lot because of the MTK glitch, so if you are careful you can take advantage of this, or loose a lot of money. Be careful.

I think you can mix serum 207's faster than any other potion. But yea, it is more expensive than strength potions at the moment.
