Purchasing all 100 packs will cost you 50,000 and yield 5000 vials. Selling those vials on the Grand Exchange for 3 each (15,000 total) nets a profit/loss of −35,000 coins.

Back when the Exchange price was as high as 80 coins per vial, the profit on reselling packs was 350,000 per restock. But this dropped drastically over the next four months:
In the first month to 60 each (250,000 total).
In the second month to 40 each (150,000 total).
Then to 20 each (50,000 total) in the third month.
And finally to 1 each (−45,000 total) in the fourth. And the price has been between 1 and 2 coins ever since.
