HR Labs Fever 40 is a capsule‑based thermogenic supplement delivering a blend of plant extracts, caffeine and vitamins aimed at supporting fat‑loss and energy.
+ Broad mix of thermogenic actives (caffeine, forskolin, hordenine, bitter orange) in one formula. + Includes Bioperine, which can enhance nutrient absorption. + Positioned as a budget‑friendly option within its category. - Uses a proprietary blend, so individual ingredient amounts are not disclosed. - Contains multiple allergens (egg, gluten, milk, soya) and a high caffeine dose that may be unsuitable for sensitive users.
The product stands out by combining a wide range of stimulant‑type extracts—caffeine (350 mg), forskolin‑rich Coleus Forskohlii, hordenine and bitter orange—alongside vitamin B6 and B12 at roughly 500 % of the NRV, all in a capsule form. Its use of silicone dioxide as a flow agent and egg as an excipient is uncommon among peers, and the brand markets it as a budget‑tier option, though the exact quantities of each active remain undisclosed due to the proprietary blend.
