This site says Cayenne Pepper's capsaicin content is traditionally linked to circulation support and a feeling of warmth.
The wording points to traditional use, not to a measured result. The two outcomes named, circulation support and a feeling of warmth, are described loosely, and warmth is a sensation rather than a metric.
On the homepage, Cayenne is grouped with Green Tea in the metabolism-support step. No amount is published, so you cannot tell how much capsaicin a serving contains from this site.
