We present searches for molecular gas (CO, OH, CS, and Ammonia) in six GHzPeaked Spectrum (GPS) radio sources. We do not detect gas in any source andplace upper limits on the mass of molecular gas which are generally in therange 1E9 to a few times 1E10 solar masses. These limits are consistent withthe following interpretations: (1) GPS sources do not require very dense gas intheir hosts, and (2) The GPS sources are unlikely to be confined by dense gasand will evolve to become larger radio sources
