Transparency is our score out of 100 for how much a vendor makes public about itself. It isn't a purity test.
Before you compare on price alone
A low price is only a bargain if the vial holds what the label says, and a high one doesn't prove quality: only an independent lab test shows what's in a vial. Check the vendor's latest batch certificate of analysis (how to read one), and see our Oxytocin overview for what's known about the compound.
