Well test is test. But when you take into account the weight of the ester, and the fact that suspension has no ester, I guess you could say that it is the strongest. My last cycle consisted of 125mg of suspension ed for six weeks. I gained a ton of weight (and a ton of water, ever though I used l-dex) and my strength went through the roof.
Now back to the part about the esters. Suspension has no ester, theirfor 125mg per cc = 125mg per cc. All other testosterones have esters which kind of act like a time release mechanism. I cant remember off the top of my head how much actuall test is in 250mg of enanthate, but part of that is the weight of the ester. So if you inject 125 mg of enanthate you are getting a slow release into the bloodstream which last several days. If you inject 125mg of suspension you are getting 125mg of suspension right then! (well actually the half life is about 4-6 hours.) but you get the picture.
