Is LEGO Nitro Muscle retired?
Yes — Nitro Muscle (8146-1) has been retired by LEGO and is no longer in production. Retired sets have fixed supply, which is why their prices are driven purely by the resale market.

What is the price per piece for Nitro Muscle?
At its $50 retail price across 598 pieces, Nitro Muscle works out to about $0.084 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Nitro Muscle a good investment?
Nitro Muscle currently trades 149.9% above its $50 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Nitro Muscle so expensive?
Nitro Muscle was released in 2007 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
