No. The concentration of test does not affect the color. The color of the aas, the oil, oxidation, additives affect the color.I've got a kit of Test C250 I received early August from Sigma, with all the conflicting info I'm not sure I'm going to keep it; but out of curiosity, shouldn't it be apparent by the color if it's 50 or 250?
Here's a pic, the first is the C250 I received from Sigma, the second is C50 I recently received, and the third is the C250 from a source I've been using for years. They are all MCT based. From the pic I'd infer that the C250 we received from Sigma is actually C50.
But not sure this conclusion would survive scientific peer review.

Last vial is either GSO (or an oil other than MCT), not Test, or is oxidized.
Why not send 1ml from your kit out for testing to Jano if you have doubts?
