About Serum 207 (2)

The Serum 207 (2) is a members-only potion in Old School RuneScape.

"2 doses serum 207 as described in Herbi Flax's diary"

Over the last 30 days it traded between 3 and 74 gp on the Grand Exchange, averaging 8 gp. About 6 units changed hands per day. The price is down 20.0% across that window. The Grand Exchange buy limit is 2,000 every 4 hours.

Casting High Level Alchemy returns 7 gp, which is 12.5% below the 30-day average price, so alching a bought one loses money.
