does eca expire?

[xenobears]

like title says, does it expire? I bought an order little over a year ago from sen nutrition, and my order got messed up so they ended up giving me a free bottle which brought the total to 3 bottles. i didnt really have a desire to use the third one, but now its staring me down and i'm thinking of taking it (its been unopened) and i just want to make sure it's still ok to use

It will but not for like 10 years or more. You are good to go bro.

sweet, ty for the answer.

follow up question though.

my brother was prescribed phentermine by his doc, and he took it for like 3.5 months but stopped because he was getting overly aggressive and wanted to take a break. so he had a 2 week supply that i asked for and he gave it to me.

i've been taking it for the past 1.5 weeks and only have a few to go. if i wanted to take eca, could i start it right away once i'm done using phentermine or should i take some time off?
