I think Mickaelia or John will wear it - A lot of new members seem to miss the pack first time and I think I’ve seen them ok them getting it on subsequent orders. Drop either of them an email to confirm. 
I think they are more concerned about us established members stocking-up on the cheap! 
Have you read this thread:
Broadly, you have three main groups of pheros - sexuals, socials and status.
Sexuals - Ammo, TUTH and IJ. These are based on Androstenone with different balancing/steering mones
Socials - IO, IH, Instant Shine - IO/IH are based on different proportions of alpha and beta androstenol with steering and IS is based on TAA
Status - IG, A314 - Both are mainly Androsterone. A314 is a complex mix of pheros whilst IG is more simple and steered more towards a lighter more social feel.
It is finding the right balance of these products for our own body chemistry/social situations that most of us find the key to a good mix. Using too much of any one group can produce a weakened/unproductive mix or one targeted at something other than you intend. Similarly, using too many products at once risks counteracting key components in the mix and sending an overcomplex signal. Simplicity is often the key to the best mixes.
IJ is the highest none product AD sell, its an intentional overdose with five times the amount of standard Ammo or TUTH. It can be good in the party scenario if you can let-go and live-up to its signal but too much none can trigger all sorts of aggressive/competitive reactions in guys and can scare younger women away. You have to accept that when using IJ, you will risk triggering fights and/or repel more people than you attract but if you find someone attuned to its signature, wow - hang-on! 
There is no direct alternative to IJ because of its steering. You could use an equivalent amount of TUTH but its sexual steering will not be quite so abrasive, or you could use plain Androstenone but again, its very raw - no steering at all. IIRC John updates the store on Tuesdays and in the past, IJ is seldom out of stock for long - Maybe a week or two at most.
TBH, the MX297 they are supplying in place of IJ is a far better party product - very social and engaging. One of the best party mixes I have ever tried. It has no none though so many of us pair it with a spray or two of TUTH to give it a more useful sexual edge that is nowhere near as stroppy as IJ.
To start a journal - Just go to the “Mens Journal” forum and start your thread. Anyone can have a journal and its a good way to keep your reports together in a way that will earn you RU status in the shortest time - which is well worth it.
One important thing to remember - Because of the issues surrounding A1 and AD no longer using it, any reports on mixes containing A1 will not count toward RU status, so keep that one as a secondary interest.
