Hey BB infact I do have the box and insert in my hand and THIS is what it reads..
First off the box itself states clearly "Storage for one month can take place in room temperature" That is directly on the box.
Now on the insert:
Number 16. Shelf Life
The powder for injection is assigned a shelf life of 24 months when stored at +2-+8C. Storage for one month can take place at room temperature.
Reconstituted JINTROPIN may be stored cold at +2-+8Cfor 7-14 days protected from light.
So there you have it maybe if Jintropin didn't work for you maybe your source took to long to send it or he had it out of the fridge as well, hence the fact you did not recieve the effects you thought you would. If I were you I would find out (look on the box) and see what day he sent it and make sure it took no longer then 2-3 weeks to get to you and you should be fine.
Also BB If that is what you read on your insert then maybe it is just plain fake bro, I know mine are real I have been dealig with the same guy for 4 years and I test every kit I get to make sure...Good luck
