Is the color variation in this 5-Amino-1MQ kit normal?

[v2boi]

Hi everyone ! received this kit and noticed there’s quite a bit of color variation between the vials. Some are a light beige while others are noticeably darker/orange.

I’ve read that lyophilized peptides and related compounds can sometimes vary in appearance between vials due to manufacturing, moisture content, oxidation, or differences in the freeze-drying process, even when they’re from the same batch.

For those with experience using or testing 5-Amino-1MQ:

• Is this amount of color variation considered normal?
• Have you received kits that looked similar?
• Did testing show any potency issues, or was everything within spec?

Everything else appears normal, but the color difference caught my eye.

Thanks!
