Standard pharmacy grade Test Cyp is 250mg/ml. The UGL can make it whatever strength they want. The test you are getting from the UGL could be higher or lower strength depending on how they prepare it. Not to mention it could be anything or a mix of more than one thing. It's possible that what you are getting from the UGL is not steroids at all. The only way to know for sure is to have it tested at a lab. However, you are asking for trouble if you show up at a lab with a handful of steroids asking for an analysis.
You can ask your UGL what strength the test is. But they may lie to you. Or, they may not know at all what it is. It's possible what they purchased the substance from someone else already prepared. There are almost too many variables to be able to give you a straight answer.
