Hey, this provides a little something you might not have had on your own *if you have put in the work*. That is the takeaway. I use it occasionally for specific training workouts that I know will simulate race efforts. I definitely use it on race day. What matters most is the work you have put into your base training so that when the time for a marginal gain oriented product like this comes, you have both variables working in your favor. Slathering this on as some sort of substitute or supplement for training is probably going to leave you disappointed and slimy feeling.
The best cream you can use to prevent chaffing and rubbing to the inner loins that grip your saddle on long days where sweat and salts by friction rub you as raw as a newbie on Cell Block 6! This stuff imparts a cooling menthol type feeling quickly upon application but dissipates very fast. I apply directly to my skin rather than rubbing on the chamois pad like some do or at times, the manufacturer suggests. Truly a needed product just like supplements for any cyclists. So do yourself a favor and buy a jar today.......a little dab will do you!
This product is a cream for your "private" and/or "tender parts" that protects against chafing from cycling shorts and chamois particularly where the inner upper thigh joins the torso (about as graphic as I care to get). It works as advertised for me. I am a casual cyclist and my rides are typically less than three hours. As this product is water soluble, heavy use and sweating may necessitate reapplication. I usually put a nice blob (tablespoon ??) on each thigh/leg joint area (but not on chamois -- my choice). It works for me and prevents a pretty large "stretch mark" on one leg joint area that can otherwise get rubbed raw. Washes off easily and completely in the shower and doesn't stain any clothing (like the chamois).
