Management, All Care /     Drops, Creams, ShotsDear Debbie, Thank you so much for your post. Please be reassured that all of our HCG pcdturos are ordered and directly received from our manufacturer or the compounding pharmacy, so there is no loss in dosage strength due to prolonged shelf or wharehouse storage. All forms (sublingual drops, injections, creams) work equally well; just remember that injections and creams must be refrigerated, oral drops do not require refrigeration but must be kept away from temperatures above 85 degrees, and cannot be left in the car during our hot spring/summer months. But don't worry, our attentive and vigilant Health Care Provider's will be there to monitor and address any obstacles that may arise during your weekly meetings, and will quickly create a plan to overcome them. Our success is only possible if our clients are successful in losing and keeping the weight off. Have a terrific day! All Care Clinics
