Adding flavor to my shakes

Hi!

I love the strawberry flavor of the Carnation Instant Breakfast!!! I like to add that to my Protein powder (vanilla or unflavored) to make it taste more like a "real" strawberry milkshake.

However, I've only been able to find the CIB assorted packets that have 2 strawberry packets and a variety of others (I like all the others too except for dark chocolate)....anyway, my stores don't sell just a container of the strawberry flavor (only milk chocolate)....

SO my question is.....

Can I add Nestle Quik strawberry powder or syrup to my vanilla or unflavored protein to make it more tasty? My stores don't carry the SF Torani syrups in strawberry, otherwise I'd just buy that. They don't even carry regular strawberry Torani syrup, but while I was perusing that aisle last night, right near the Torani syrups were the chocolate milk mixes, hot cocoa, etc. and that's what got me thinking about adding the strawberry Nestle Quik when I want a strawberry flavor. My daugther wouldn't drink plain white milk when she was a little younger but would happily guzzle it when we added the "magic" syrup (strawberry nestle quik) to make it into "princess milk"....(whatever works to avoid a power struggle with a 2-year-old!)

I know the Nestle Quik has lots of sugar and probably calories, but I'm talking maybe using a teaspoon or so, just to perk up the flavor.

Any ideas?

Thanks!
