Top in my book
Let's say, in this industry, it's hard to find companies with integrity that do what they say they'll do. Sigma wins at this hands down. Fast shipping, great compounds that you don't have to worry about not reconstituting, which I have had happen with other companies.

Excellent service
Excellent service. Despite a shipping glitch (not the company's fault), they offered me a discount on the purchase of replacement items.
