Serum 208 (4)
Serum 208 (4) is a members item. No shop sells Serum 208 (4) and no monster drops it, so an Ironman makes it: it takes 15 Herblore, using Serum 207 (4).

Ironman verdict
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. Serum 208 (4) is members-only. It is untradeable, so every account, Ironman or not, gets it the same way.
