I respectfully suggest you reconsider your priorities.
Trimix is not like viagra cialis or levitra that come in pill form of a specific strength. Trimix is an injectable pharmaceutical that is compounded to a formula that meets the specific needs of the individual. Those needs are for the length of time of an erection and it’s strength. The permutation of just those two variables make the number of possible formulations nearly endless.
Your first concern should be finding a prescriber that will work with you to get the formula that best meets your needs. Only then can you think about shopping around.
And if your considering volume discounts especially from an Indian mail order pharmacy please note that Trimix must be refrigerated at all times and has a shelf life even when refrigerated of only three months.
