Only in one vague study done on horses. That's the thing. If you've ever done suspension, especially in a muscle that used often, there's no week-later peak or spike. Not that I've ever noticed. Seriously. Not even trying to be argumentative but does that really add up? Human physiology determines how suspension and all IM injections work. Not studies with horses. Even the clinical pharmacology from the manufacturer that requires a great amount of R&D show a much shorter absorption mechanism of action within just a few hours. If some residual testosterone is left at the injection site, it would be cleared in a timely fashion perhaps over a day or two. Not a week later. Even if there is residual compound in the muscle, why would it just decide to absorb a week later? It's highly questionable to say the least. I would never do a suspension that was 100mg/ml. That's just asking for trouble. If you make a cup of tea, would the sugar suspended in the tea be more likely to settle if you put one teaspoon of sugar or four?
