9. A method of loading a syringe with a correct dosage, comprising
mounting a left-hand bottle and a right-hand bottle in a bottle cradle of a syringe loader, mounting a syringe in a groove in a syringe carrier of the syringe loader, filling the syringe with an amount of air equal to a desired total dosage without reading any graduation markings on the syringe by pulling the syringe plunger back to a dosage stop indicator affixed to the syringe loader, inserting the syringe needle into the left-hand bottle by aligning the bottle cradle and syringe holder and moving them together, injecting into the left-hand bottle an amount of air equal to the required left-hand bottle ingredient dosage by pushing the base of the syringe plunger into contact with a removable dosage gage mounted in the path of the plunger base, withdrawing the needle from the left-hand bottle by moving apart the bottle cradle and syringe carrier, inserting the syringe needle into the right-hand bottle by aligning the bottle cradle and syringe carrier and moving them together, injecting into the right-hand bottle an amount of air equal to the required right-hand bottle ingredient dosage by removing the dosage gage and by pushing the syringe plunger as far forwardly as it goes, loading the syringe with a slight overdosage of right-hand bottle ingredients by pulling the syringe plunger base back past the dosage gage, obtaining the correct dosage of right-hand bottle ingredients by moving the dosage gage into the path of the plunger base and pushing the plunger base against the dosage gage, withdrawing the needle from the right-hand bottle by moving apart the bottle cradle and syringe carriage, inserting the syringe needle into the left-hand bottle by aligning the bottle cradle and syringe carrier and moving them together, and loading the syringe with the correct dosage of left-hand bottle ingredients by pulling the syringe plunger base back to the dosage stop indicator.

10. A method of loading a syringe with a correct dosage, comprising
opening the forward end of a bottle cradle by turning a forward bottle retainer into vertical position on a bottle cradle having left and right-hand seats for two bottles, opening the top of a bottle cradle by turning an upper bottle retainer into a position parallel to a separator between the two bottle seats, inserting a bottle into the left-hand seat and inserting another bottle into the right-hand seat, closing the forward end of the bottle cradle by turning the forward bottle retainer into horizontal position in contact with the bottom of the bottles, closing the top of the bottle cradle by turning the upper bottle retainer transversely into contact with the side wall of the bottles, taking a syringe having a barrel with a collar at its rear end and a needle extending from its front end and having a plunger inside the barrel with a flange at the rear end of the plunger, placing the syringe in a syringe groove in a syringe carriage and seating the syringe barrel collar in a collar slot in the syringe carriage, holding the syringe in the groove by rotating a syringe retainer across the top of the groove, filling the syringe with an amount of air equal to a desired total dosage by pulling the syringe plunger back to contact the dosage stop, inserting the syringe needle into the left-hand bottle by turning the syringe carriage counterclockwise and moving the carriage forwardly as far as it will go into contact with a needle spacer mounted on the bottom cradle and inserting a carriage aligner pin in a right-hand aligner hole of the bottle cradle, rotating the dosage gage across the syringe plunger, injecting into the left-hand bottle an amount of air equal to the required left-hand bottle ingredient dosage by pushing the syringe plunger forwardly to bring the bottom flange of the syringe plunger into contact with the dosage gage, withdrawing the syringe needle from the left-hand bottle by pulling the carriage back into contact with the carriage stop, inserting the needle into the right-hand bottle by turning the carriage clockwise and moving it forwardly as far as it will go into contact with the bottle cradle needle spacer and inserting the carriage aligner pin into the left-hand aligner hole of the bottle cradle, freeing the syringe plunger to move forwardly by removing the dosage gage from across the plunger by rotating the dosage gage clockwise, injecting into the right-hand bottle an amount of air equal to the required dosage of right-hand bottle ingredients by pushing the plunger forwardly as far as it will go, loading the syringe with slightly more right-hand bottle ingredients than required by holding the carriage against the cradle and pulling the plunger back so that its bottom flange clears the dosage gage, moving the dosage gage across the plunger by rotating it counterclockwise, obtaining the correct dosage of right-hand bottle ingredients by injecting back into the right-hand bottle the overdosage amount of right-hand bottle ingredients by pushing the plunger forwardly so that its bottom flange contacts the dosage gage, withdrawing the needle from the right-hand bottle by pulling the carriage back away from the bottle cradle until the carriage contacts the carriage stop, inserting the needle into the left-hand bottle by turning the carriage counterclockwise and moving the carriage forwardly as far as it will go into contact with the needle spacer and inserting the syringe carrier aligner pin in the right-hand aligner hole of the bottle cradle, removing the dosage gage from across the plunger by rotating the dosage gage clockwise, loading the syringe with the correct dosage of left-hand bottle ingredients by holding the syringe carriage in place and pulling the plunger back into contact with the dosage stop, removing the needle from the left-hand bottle by pulling the syringe carriage back to the carriage stop, whereby the syringe has been loaded with the proper dosages of left and right-hand bottle ingredients, freeing the syringe from the carriage by moving the syringe retainer from across the syringe barrel, and carefully removing the syringe from the carriage without changing the setting of the plunger or touching the needle, whereby the syringe is ready for injecting the correct dosage.
