"The advantages of a topical application are self-evident. Dr P.,you have first hand experience with peptide copper compounds; how is the Grafcyte(TM) product different from the Tricomin(TM) solution? Is it just different packaging?

It is a little different compound. But most compounds with this kind of SODase/antioxidant activity stimulate hair growth. This includes the original one, a drug called "Orgotein", which is approved for veterinary use in the US and Human use elsewhere.. If you have the activity, ya don't even need the copper, as NCI researchers report with another such agent ( TEMPOL ) in enhancing hair regrowth in radiation alopecia..

Also, are FDA approval standards less stringent for topical applications?

As a general rule, yes. In fact, if it is a "cosmetic" ya don't even need FDA-approval per se. Ya just can't make any drug claims. A whole new class of agents ("cosmeceuticals" ) has arisen that's half-way between.

Also, a recent supreme court ruling ("22 liquormart") essentially gives first amendment protection to commercial speach, if it is true. This undercuts the whole FDA thing ( thank goodness ). We are now seeing drug companies indirectly promote off-label uses for their drugs. E.g., Merck is now promoting Propecia by having their researchers go around giving "seminars", with Merck sales people present. They would not have done this before. Interesting times are coming in the drug trade <G>.

BTW, Procyte was really smart and got Iamin gel (TM), and Graftcyte (TM ) thru as "medical devices".
