Many thanks for the replies. I will give it a go when I get home from work. You have helped me get out of this conundrum. Sorry if this offends anyone "Glory to the Empire! My the death of the Jedi order be swift, and the galaxy ruled by the power of the Sith."

Is this in the Diplomacy missions, how do I choose a lower level, as only grade 4 companion gifts and medical supplies seem to be available. Thanks for the quick responses!

Greetings. I appreciate any help you can provide on this matter. I didn't spend much time on Crew skills initially as I got swept up in the game, however I did keep sending my companions out on diplomacy missions to increase my darkside points and get companion gifts. However I am now trying to increase my biochem and can't get any biochemical compound as I only can get grade 4 medical supplies. Is there anywhere I can purchase it? I apologise if this seems a bit of a noob question, but we are all ignorant at one time or another.
