Most Deca 300mg brands available in Mexico are quite high in quality, in comparison to other vet products. The same can be said for Equipoise as well, for whatever reason. It's when you get into the Testosterones, is when Mexican Vet-lab quality can vary from brand to brand. Tornell isn't exactly high on the quality list. Not at the bottom, but close.
If I were at a granero, I would select my Deca in the following order:
1. Ttokkyo Labs. 10 ml vial. 300mgs/ml. They are still making AAS. No more "K" though obviously. Being that is isn't the same person running the company now, I will question the quality until I can see for myself. I used their Nandrolona 300 specificly before the company was shaken down by the Feds.
2. Quality-Vet. Same as the TT.
3. Brovel Norandren 200 50ml jug. Their products have at times been tested at below the acceptable minimum amount of milligrams per cc. Still though, the price on that huge ass jug can't be beat if you are hurting on cash.
