before i reply, i want to say that i am definitely new to this forum, so i don't claim that i haven't asked any dumb or slightly repetitive questions. but...
before asking about phs or
6-oxo or a myriad of other supps listed on this website... click on that little word "assistant" on the upper left side of your screen. this will allow you to search for topics in the various forums. in your case, you will probably find more information than you care to read on the question you have asked. when you ask a question without doing any sort of reasearch, it's obvious. the mods here are incredibly erudite and usually pretty patient, but i imagine they're getting a little tired of answering the same questions over and over again. so, before you ask anything else about phs or supps or whatever: 1)search the forums for the pertinent information and 2)read the articles posted on this website (try google, also... never know what you'll find). that said, if you want first-hand accounts of product results, then look up the product and click "reviews". it's straightforward, and it will stop cluttering up the boards with the same old stuff. phew. sorry that was long-winded, but you gotta put a little effort in before you appeal to the mods for redundant info. oh, and short answer to your question:
S1+, as it stands right now, is probably the best ph for your goals.
