5-HTP vs. Serotain

[umich]

Swim was recently looking in a Manhattan vitamin shop for some 5 HTP and came across a bottle of something called Serotain, which, after reading what was said on the bottle, seems to do the same 5 HTP does. It looked like the main ingredient in Serotain was 5- hydroxytryptophan. Anybody see the same thing or have any insight? BTW don't bother purchasing either of these in Manhattan (Midtown). Cheapest bottle was $28 and ranged up to $36. WAY overpriced, SWIM is used to paying something near the $15 range.
