In conversations with chemists, there is no evidence Laxogenin needs to be in a sub-lingual or cyclodextrin base, although I suppose it couldn't hurt. 400mg is a very large dose, as Laxogenin (one of a family of 4 compounds studied by the Russians) was found effective in a dose as low as 25mg. Indeed, the whole point of these compounds (compounds 1-4 in the former Soviet literature) was that they were effective at a much lower dose than the reference "base" compound, Ecdysterone.
Laxogenin is a fine compound, but like Ecdy needs certain other ingredients to exert its full effects. One of those should be an optimal testosterone level, as castration of the animals in the study I'm thinking about showed much inferior growth rates. You don't need supraphysiological levels, but rather optimal will do (750 to 1,000ng/dl). Beyond this, a compound to increase feed efficiency/appetite is useful, as is an ingredient to replenish phosphagens (creatine).
If you're cutting, it's much more important for Ecdy to be complexed with ingredients that replenish cellular energy, which takes a nose dive on lower calories/carbs and immediately following training. That's why you get weaker on a diet, that's why you feel lousy and that's why many tend to go, "flat". Replacing cellular energy (without the normal caloric load), acting as an anti-inflammatory and dramatically accelerating recovery are what Ecdy/laxogenin do best. And they do it better IMO than anything else.
Legal, anyway...
