Serum 207 (3)
Serum 207 (3) is a members item. No shop sells Serum 207 (3) and no monster drops it, so an Ironman makes it: it takes 15 Herblore and gives 50 Herblore XP, using Tarromin potion (unfinished) and Ashes.

Ironman verdict
Where the materials come from: Tarromin potion (unfinished) (made with 5 Herblore); Ashes (made with 30 Cooking). Making ten takes 10 × Tarromin potion (unfinished) and 10 × Ashes and gives 500 Herblore XP. Reaching level 15 Herblore takes 2,411 XP in total; the Herblore calculator counts the actions and materials to any target, and the Herblore guide has the Ironman training route. One recipe uses Serum 207 (3): Serum 208 (3). Serum 207 (3) is members-only. It is untradeable, so every account, Ironman or not, gets it the same way.
