The Nyloxin/Cobroxin differences/non-differences continues being a quagmire. Originally when Nyloxin was announced, Rik himself stated that the 2 are 100% identical, just the name was changed for international marketing reasons, unless at some point in time a decision was made to release a stronger product that was still considered to be an OTC product, but the company has not fully clarified this, thus the confusion. The other part that sounds stupid, is that if in fact Nyloxin is a stronger version and better for most people, why is it only going to be offered online in the US, instead of phasing out Cobroxin and replacing it with Nyloxin on the US shelves. There is too much segmenting going on for a less than 1 year old product that is still trying to gain repeat customers. Does NPHC really need 4 different strengths of the same product (lowest to highest strength) 1. Cobroxin OTC, 2. Nyloxin OTC, 3. Nyloxin OTC Extra Strength, 4. Nyloxin RX? I could see possibly 3, combine Cobroxin/Nyloxin into a single slightly stronger product, make the Nyloxin ES also available as an OTC, and the a single Nyloxin RX if it is really necessary. But in reality, you can just increase your dosage and achieve the same effect without having to fragment/segment the product when the only difference is the dilution of the active ingredient.
Cobroxin works great for me, but I already need to double my dosage for the desired effect (severe nerve impingement from herniated disks), basically making me take Nyloxin without buying it. Since I effectively use 2 bottles a month, it would make more senese for me to buy the Nyloxin in the first place as at $25, it's cheaper than buying 2 bottles at $18.99. And would make buying the Nyloxin ES at $35 or even $45 at 4 times the strength even more cost effective since I'd only need 1 spray 3 times a day as opposed to the current dosage. The product needs to be on the store shelf to make it accessible to more people however, and this online only arrangement is a pain in the ass for regular customers like me.
