What Is THCp and Does Mellow Fellow THCp Get You High?
THCp (tetrahydrocannabiphorol) is a naturally occurring cannabinoid first isolated by Italian researchers in 2019. It has become one of the most talked-about compounds in the hemp-derived cannabinoid market. Mellow Fellow offers THCp across disposables, cartridges, edibles, and flower. Here is what you actually need to know.
The Science: Why Is THCp So Potent?
THCp has a seven-carbon alkyl side chain compared to Delta-9 THC's five-carbon chain. This structural difference gives THCp much higher binding affinity for CB1 receptors — in laboratory studies, up to 33x greater affinity than Delta-9 THC. This does not mean exactly 33x more intoxicating in practice, but it does mean a small amount goes a very long way.
What Does THCp Feel Like?
Users consistently report longer-lasting and more intense effects than Delta-9 THC at equivalent doses. Body effects are particularly pronounced — deep physical relaxation, heightened sensory perception, and extended duration often 3-6 hours for edibles. At low doses it can feel similar to a potent indica hybrid. At higher doses it is genuinely overwhelming for most people. This is not a product for first-time cannabis consumers.
Mellow Fellow THCp Products Available
The THCp Bursts edibles range from 2.5mg (entry-level) to 25mg per piece (experienced consumers only). THCp is also present in blend products including the Destination Series disposables and Max Dose gummies. The hash hole THCp prerolls represent the most complex delivery — combining THCa flower with a THCp-enhanced concentrate core for extreme potency.
Dosing Guidance: Start Extremely Low
New to THCp: start with the 2.5mg Bursts edibles. Take one piece and wait a full two hours before considering more. For vapes, one short draw is sufficient to start. THCp's extended duration makes overconsumption easy. The 25mg edibles are strictly for consumers with very high cannabis tolerance. See our FAQ for compliance and dosing details.
