Just received Lifeline - how much to give?

Just received my bag of lifeline and needing help on how much to give my chinny. He has lost 40-45g of weight over the last few weeks. Be broke his foot (which is healing nicely) but we had to separate him from his cage mate and he has pretty much stopped eating of drinking anything. Ou reason he is still here is because he has been fed CC 3 times daily. I've heard this lifeline works wonders but I am airflow confused as to how to use it. Do I mix it in with the CC or feed it separately? I understand this is not a meal replacement like CC.any help would be great x
