I'm restarting my cycle I stop because I had a torn hamstring. I order more Test Cyp (BD) brand but I notice this one had a darker color like a golden yellow, doesnt look like the others I bought before I check every were even in the BD website for legitimate but all looks good in the bottle, Label, Date rubber seals, and the cap havent been broken. It is possible that the mixture of the quemical tends to change color. Or I should worried. My source always been Legit.
