There are a good number of threads on what works with Indian women here already if you want to search but I must say that IME, although A7, SOE and A314 are all good products, any mix involving A314 and SOE together will not be amongst them.
The reason - A314 is badly weakened by the alphanol in SOE, so they effectively cancel each other out, making it a waste of both products. SOE is also difficult to dose effectively.
You also run the risk of different forms of OD with all of those combos because all of the products contain common primary components that are liable to throw the proportions of any mix right off - eg liquid trust, A7 and SOE all contain Androsterone, whilst liquid Trust, A7 and MAG in any combinations is an Androstenone OD waiting to happen.
Which brings us to the next problem - MAG is a very overt Androstenone product that most guys find very difficult to use effectively and its overtness would severely limit its use to all but the raunchiest clubs/parties, around older women or with an established partner.
Oxytocin is not a phero and the jury is still very much out on its effectiveness in a phero-like context - for dose, proximity and absorption.
You also don’t give us any idea of where you are hoping to use these pheros or the age range of the women you are interested in. This is all important as mixes may well differ for women in the mid 20s and below, compared to what might suit those pushing 30 and above. So this info all helps us make better suggestions.
Personally, the best mix I’ve found around Indian women of mid 20s and over is A314, Instant Honesty and the Putative pheromone P74 - This basic mix can be used effectively in all kinds of situations (it is also a superb professional and fallout mix), then it can be sexualised by simply adding an Androstenone product like TUTH when things relax and get social/sexual, but my best results by far have been with the non-AD product NPA - again there is plenty here already about using that one.
If you are looking at oil base products because of heat, there are several strategies for using sprays better in hot weather, again there are many threads on the subject.
