A two-letter imprint from a reputable-looking shop. The packaging is the part that bothers me.
Light quality ruins more identification photos than anything else. Daylight, no flash.
Asking a pharmacist costs nothing and they can weigh and measure what a description cannot convey.
Holograms are the least useful check because they are the one everybody makes.
Happy to be told it is nothing.
You are not imagining it and you are not being difficult. Document it and take the document in.
How do you get a clear photo of an imprint? Mine keep coming out blurry.
Daylight, no flash. Side effects was my main issue with a two-letter imprint too.
Take one to a pharmacist. Free, two minutes, correct. Everything else here is a hypothesis.
Sorry, probably obvious, but where do you even start with something blank?
My pharmacist has become my actual doctor and I am at peace with it.
