I dunno. This stuff reminds me of what they do to wheat. First they mill off the really nutritious parts. Then they put some of the vitamins they just took out back in and tell you they've enriched the product.
This is true of some but not all concentrates. You really have to examine how each trate is produced, eg., some trates are made by combining isolate with non-cannabis, plant terpenoids - I avoid these completely. The best but most expensive is full spectrum live rosin, which is a solventless trate made from flash-frozen plant material with nothing added.
I purchased on-line on 420 some full spectrum, hydrocarbon-produced CBD resin with nothing added for $26/gm discounted (Ashville-extracts), which is still excellent quality but less expensive than rosin. Live rosin THC cannabis trates are much more expensive, $80/gm at least.
Also becoming very popular is to flatten flowers with heat in a dab press so as to squeeze out pure cannabis rosin that can be dabbed immedately in a dab rig using either an enail or an isobutane torch, or a portable dab rig, like the DTV4 or the Saionara.
resin = solvent produced trates
rosin = solventless trates
live = flash-frozen
full spectrum = no distillate, no isolate, includes all the cannabinoids, terpenoids, & flavonoids from the original plant
