Synthacaine chemical has had a rather bad reputation in the research industry. Subsequently, this is because  many companies are selling very low quality samples of it. We work closely with a reputable laboratory to ensure that our synthacaine is at least 98% pure. This is a very strong and popular stimulant. We do not release the exact formulation of this product. This is because it is a proprietary blend but  the main ingredient is methiopropamine.
