The best frontload is an oral, which puts you in an anabolic state almost immediately. But even an injectable doesn't take that long. I've seen rises in T via blood test within a couple of hours following a first shot.
When people say it takes weeks for a steroid to kick in they're simply mistaken. Most steroids are active (excluding a weaker half life period) for about 10 days. So the first shots don't do anything? Ridiculous.
It may take a couple of weeks to see gains (though it should occur sooner) but the anabolism is pretty quick. Make the most of it.
