No I have the real thing test susp made from syno. I want to use it as a race day enhancer, I have used it for the past 3 weeks only 150 mg in total, I have it in 1000 mg in 40 ml bottle of B12 I wanted to see how the body responded. I can feel 50 mg slightly. one cc shot should be 25mg if my scale is right. My question is do I need anti-est for a once a week pre race boost. just for that freshness factor.
