What is the shelf life of transdermal prohormones?
This depends on the substance; in general the shelf life is 1-2 years. This can be increased by freezing and/or vacuum sealing. If you are planning on stocking up you are better off buying bulk prohormone powders and then mixing them in a carrier before use.
