No offense but loeffler is probably the worst of all the mexican companies. AP, Powerline, Denkall, QV and SYD are your top of the line. Denkall, QV and AP all coming from the same corperation Salvet. Brovel and tornel are actually a father/son combo. I cannot remember the family name but the father owns brovel and his son own tornel. Syd is a good company. But loeffler isnt really credible. Yes they make reforvit B but to be honest that is probably the only good product they make.
Now like brovel and tornel, they are major pharmacutical companies in mexico who sell and array of vet care products to vet shops so steroids are not thier sole money maker as is for QV,AP, Powerline, SYD, Denkall, etc. So I doubt the accurate dosing is a not a real concern for those companies.
Granted I personally like tornel and brovel. I would still use them today if I didnt have anything around and to be truthfully honest in 30 years when all the dust and smoke settles and sure they will still be there long after denkall, QV, AP, SYD, and the rest are all gone. They were the first and I am sure they will most likely be the last.
