Klein Becker’s Anorex / Leptoprin Fat Burner Review

Anorex (also known as Leptoprin), is a highly priced fat burner from Klein Becker. It’s marketed aggressively, and gives the succinct impression it is some sort of weight loss wonder drug, “available without prescription” (not all that surprising really, considering that “Klein Becker” sounds a lot like a drug company, and Anorex Leptoprin sounds a lot like a drug).

According to Klein Becker…

“Anorex is an extremely powerful anorectic agent and is not intended for use by the casual dieter who is merely attempting to shed five or ten “vanity” pounds.”

Uh-huh. Typical advertising hogwash.

This review is of the Anorex / Leptoprin ephedra-based fat burner which has been discontinued by Klein Becker because of the ephedra ban. I’ve left the review up for your convenience (I’ll be reviewing the ephedra-free version of Anorex soon).

(If you’re an ephedra fan interested in obtaining ephedra safely and legally, check out my review of “The Black Market Report On Ephedrine.” if you’re looking for a recommendation for an ephedra-free fat burner, check out my review of Lean System 7.

In fact, this review of Anorex Leptoprin was initiated by e-mails from angry readers who felt they had been duped by Klein Becker. Here’s the thing though…

Despite the outrageous hype surrounding Anorex, the formulation is more than sound, it’s actually pretty good.


Ma Huang, caffeine, ASA, and kola nut form the base for what is known as the ephedrine stack — a powerful combination proven to be effective for fat loss. It’s even more powerful than some prescription diet drugs, and there’s even some real clinical data to validate its effects! (I’ve written a ton of material on ephedra and ephedrine on this web site, so I won’t rehash it all in this Anorex review.

However, I must caution you… do not experiment with an ephedra based fat burner before investigating other articles at Ultimatefatburner.com).

Also included are…

1. Green tea: a wonderful anti-oxidant, but more importantly displays glucose moderating activity, and is therefore very helpful for balancing blood sugar and crushing cravings. It also has the ability to boost the metabolic rate, and unlike many natural fat burnersa, actually has a decent amount of clinical data validating its effectiveness (see the full review green tea for validation!).

2. L-tyrosine (reviewed in full here!): an amino acid that may have a beneficial effect on mood, as it is a precursor to several neurotransmitters. It also may contribute to an elevated metabolic rate by positively affecting thyroid levels. In “Dr. Atkins’ Vita-Nutrient Solution”, Dr Atkins describes L-tyrosine as an effective antidepressant…

“The amino acid works better than the majority of antidepressant drugs, costs less, and helps all of us think better when we’re under stress.”

Unfortunately, fairly high doses are rquired to obtain results… in the order of three grams per serving. There isn’t anywhere near that amount in this formula.

3. Kelp (standardized for iodine): May help encourage proper thyroid activity, but data validating this claim is in short supply. Kelp also has a tendancy to concentrate heavy metals, and needs to be approached with caution for that reason. Additionally, elevated levels of iodine can cause more harm than good for people with conditions of hyper/hypo thyroidism.

Cayenne, calcium, and vitamin B6, also included aren’t big winners, but they don’t hurt this compilation much. Unfortunately, there is a major problem problem with Anorex Leptoprin (and it’s the reason readers wanted an Anorex review)…

The price.

At $129.99 per bottle, that’s about 3 to 4 times what this product is worth, despite its effectiveness. The original ephedra-based Hydroxycut or even Xenadrine’s RFA-1 are much better bargains — and they’re no less effective.

Klein Becker also has a serious credibility problem. According to this release by the FTC, Klein Becker…

  • fabricates clinical trial results
  • makes completely unsubstantiated claims which cannot be validated by any research
  • misrepresents the fact that one of its founders, Daniel Mowrey, is a medical doctor.

As such, you have to call into credibility any of the claims this company makes about its products.
