Caffeine

The chemical formula for caffeine is C8H10N4O2. Thus:

line 1: The total number of atoms (“members”) comprising a caffeine molecule is 24 (“twenty-four”) (8+10+4+2). Caffeine is a stimulant for the nervous system, therefore making it a chemical compound which is a “lively blend”.

line 2: The “C8” of caffeine (or C8H10N4O2). Eight (8) atoms/members of caffeine are those of carbon, which can become diamond under sufficient and prolonged pressurization (“pressured”). The phrase “for a girl to befriend” alludes to the saying “diamonds are a girl’s best friend”.

line 3: The “H10” of caffeine (or C8H10N4O2). Ten (10) atoms/members of caffeine are those of hydrogen, which is an element (symbol: H, atomic number: 1) found at the top left-hand corner of the periodic table of elements, i.e. “at the head of a table’s left end”.

line 4: The “N4” of caffeine (or C8H10N4O2). Four (4) atoms/members of caffeine are those of nitrogen, which makes up about 78% of the Earth’s atmosphere.

line 5: The “O2” of caffeine (or C8H10N4O2). Two (2) atoms/members of caffeine are those of oxygen, which is released by a plant (“a leafy friend”) through the process of photosynthesis.

line 6: Caffeine delivers “rejuvenation” (i.e. a boost) to “your system” to make you feel more energetic.

For the first hint, caffeine is a stimulant, so it can “pick you up” i.e. give you energy, if you drink coffee, for example, or some other beverage containing caffeine “in the morning”.
