SWIM sees the point. Yes, it is quite frustrating not knowing why and it is difficult to trace the reason for the recommended (from the suppliers) storage temperatures.

SWIM has the tendency to disagree with the recommendations that come from the companies. Not always but sometimes. In many occasions he has stored materials in the freezer while the company recommends fridge storage and he has found no loss in quality. He's talking about storing biomolecules such as purified antibodies which are quite prone to degradation resulting from temperature differences.

SWIM believes that no good/accurate studies are always performed when a company decides the temperature storage of an X chemical. He thinks it usually goes like that:

1) some of the X substance is kept at room temperature, some in the fridge and some frozen.

2) after a year or so quality of the product is assessed.

3) and if fridge storage is as good freezer, then fridge storage is recommended.

The MSDS for freebase 5-meo and (the attached pdf) do not state something like "avoid freezing". Strassman as far as SWIM remembers was keeping his dmt fumarate in the freezer.

In the end not much point arguing this kind of stuff. It would be quite interesting to see whether salts kept in the freezer lose potency compared to those kept in the fridge. And doing this kind of studies (i.e. bioassays) is always fun:wink:
