Every human carries an amino acid complex of scent in varying degrees...leaving behind the predatory scent component L-Serine, in each and every fingerprint.

So what does that have to do with fisherman?  

L-SERINE -  As seen in the diagram, it is in high concentration in human fingerprints.  In the early 1950's, J.R. Brett and D. Mac Kinnon did their classic studies to determine this repellent scent to fish.  They tested over 54 different substances such as soap, pine oil and brasso, by dropping the dilute scents above a fish ladder during a salmon run.  The only major repellant found were pieces of skin from natural predators of the fish including bears, seals and humans. Some of the fish actually jumped back down the ladder.  This ability to detect their predators at a distance by smelling L-SERINE and to be alert for danger must be a distinct survival value.

A lure contaminated by human fingerprints can turn the fish away.  Remember fish have the most elaborate, sophisticated, and sensitive olfactory apparatus in the entire animal kingdom.

There are two methods of covering up these repellent fingerprints.  One is to use a very strong “cover up” odor, like anise oil, fruit scents or garlic, like in many popular fish attractants.  This approach risks alarming the fish because of the alien and confusing effects of these odors. In contrast, Dr. Juice Fish Scent uses an amino acid profile to eliminate the human fear odor.  This amino acid profile changes the pattern of the fish’s brain responses and eliminates the fear response. An analogy of how this works is that the repellant L-SERINE amino acid is not perceived as a single and menacing “peak” among rolling hills as seen in the diagram.  It is instead, camouflaged, only to appear as another hill in a mountain range. This subtle camouflaging effect of attractant amino acids make the L-SERINE very nondescript without confusing or alerting the fish to anything “out of the ordinary”.

Dr. Juice Hand and Lure Cleaner is a successful antidote - a dramatic breakthrough that counteracts the L-Serine scent by breaking down the molecular structure.

Dr. Juice Hand and Lure Cleaner

The low-foaming revolutionary cleaning formula that neutralizes offensive odors that are a repellant to fish, deer, and other game.

• Breaks apart the fish repelling amino acid L-Serine left on lures by human fingerprints.

• Cuts grease, grime, oil and gasoline. (Good all-around cleaner for the camp, garage, and home).

• Removes offensive odors and residue left by sunscreen, insect repellants and lotions.
• Maximize the performance of attractant fish scents by cleaning lures and hands before
