TPQC is another clone from SAB member Nitrogen. The ID of the species changed repeatedly in the past, but it is probably a Trichocereus peruvianus. It developed crested growth after an injury, but is generally not a crested clone and I have never seen one of the cuts revert back to crested growth. It is probably best to consider it a normal clone of Trichocereus peruvianus.
