The vials are Test Cyp and Deca. I live in Brazil and temperatures are always between 20 and 43 °C. It is commonly known that roids need to be stored at room temp. But at THIS temperature???

My first instinct was to store it at +5°C in the fridge door (least cold). However, some say this will form crystals in the liquid etc etc. Other say that crystals will dissolve easily by warming up. Other say heat makes the gear loose its potency. etc etc.
Anyone some ideas?
Your help would be greatly appreciated.
