Hi, i am new here and and getting ready to purchase a panther chameleon in the near future. I bought a nice used set up for him from someone online and it came with the Herptivite Multivitamin Supplement and Rep-Cal Calcium w/ D3. The labels say they expired august and october 2011. Both are nearly full so my question is should i toss them and get new ones or are they ok to use still?
