I believe the answer is:

generative

I'm a little stuck... Click here to teach me more about this clue!

'up' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I don't see?

'having the means of production i've reagent to get' is the wordplay.
'i've reagent' can be anagrammed to 'GENERATIVE'.
But, I am not sure how this is indicated.

'made' acts as a link.

Can you help me to learn more?

(Another definition for generative that I've seen is " Capable of reproduction".)

I've seen this clue in The Times.
