Biotest has been making much ado about Fahrenheit, its fat burner “especially” formulated for women. A quick glance at the ingredients however, elicits a distinct feeling of “deja vu”. In fact, if you’re familiar with Biotest’s HotRox (Hot Rox) fat burner (reviewed here), you’ll recognize that Fahrenheit as nothing more than a watered down version of that same fat burner.
Although the Hot Rox / Fahrenheit compilation is somewhat different than your typical fat burner, feedback on its effectiveness has been decidedly mixed. Actual real clinical data establishing its effectiveness is in short supply too.
So what’s in Fahrenheit?
Well, like Hot Rox, there’s A7-E, Sclaremax, guggulsterone, and caffeine.
Caffeine is a moderately effective thermogenic common in most fat burners, but most effective when stacked with ephedra and caffeine. In the Hot rox formula, however, caffeine may help to improve the performance of one other ingredient in this formulation — sclaremax.
A7-E, sclaremax, and guggulsterone — in these three ingredients lies the backbone of the Fahrenheit formulation.
According to Biotest, A7-E is a thyroid supercharger, increasing levels of T3 thyroid hormone up to 30% (at this point though, there’s no irrefutable data to indicate that this is the case — but we’ll see). A7-E is supported by guggulsterones, which are also believed to have a positive impact on thyroid hormones as well as positively influencing cholesterol levels. Several studies validate the value of guggulsterones for elevating thyroid hormone levels.
Sclaremax (actually the extract of the Salvia sclarea plant), may be more effective than Coleus Forskohli at increasing cyclic AMP (a cell regulating compound). This may lead to a raising of thyroid hormone levels and further spurring weight loss. Alas, the validity of sclaremax is also largely undocumented at this time.
Bottom line on Fahrenheit for women?
If you’re interested in Fahrenheit, you’d probably be better off trying Biotest’s Hot Rox. The formula is a little more extensive, and probably a little more effective.
