Thank you for your inquiry.
In this case, your provider prescribed a newer formulation available through our pharmacy: Testosterone Cypionate in MCT oil. This selection was likely made due to several clinical and practical advantages compared to other carrier oils, such as grapeseed oil. For specific clinical reasoning behind this change, we recommend discussing it directly with your provider. Key benefits of the MCT oil formulation include:
Extended beyond-use dating (BUD) of up to 90 days, compared to 60 days for grapeseed oil
The ability to prescribe up to two vials at the same time
Faster onset of action compared to other oil-based formulations
When refrigerated, the MCT oil formulation maintains the extended 90-day BUD. If the vial was not refrigerated upon its arrival, the medication remains safe to use; however, the BUD is reduced to 60 days from the date of compounding. For optimal comfort and reduced injection-site irritation, we recommend allowing the medication inside the syringe once drawn up to warm to room temperature prior to injection, while keeping the vial refrigerated between doses.
Please note that all cold-ship products from our pharmacy are shipped via FedEx overnight delivery. Non–cold-ship formulations, such as Testosterone Cypionate in grapeseed oil that you may have received previously, are typically shipped via ground delivery and may not be sent through FedEx. If you prefer the prior formulation Testosterone in Grapeseed Oil in the future, please notify your provider so that future prescriptions can be adjusted accordingly.
