    Old Blue Tops Kit Still Good?

    I have a GH kit that’s been in my fridge since 2015, still good? Wafers still intact, dilutes normally.

    Im sure it is.

    Pharmaceutical manufacturers have to study the stability of drug products before marketing according to ICH guideline Q1A(R2); data of those investigations aim to set expiry dates. The expiry date on the container of a remedy assures the physician and the patient a stability of the drug in its formulation i.e. within a specification of 95-105%. Only few studies show that shelf-lives of pharmaceutical products are often longer than expiration dates.

    Growth Hormone not mixed generally would have an expiration date of 2-5 years.

    This study below measured medications in ampules/vials that were 40 years past expiration. 5 out of 9 products remained at full potency while 4 of the products only retained 70-80% potency
    https://pubmed.ncbi.nlm.nih.gov/29274583/

    Also for lypholized powders, consider the following:

    Storage conditions and storage time. A change in reconstitution time may be observed during storage of a PI. Common reasons include cohesion, crystal growth, and/or moisture sorption, which promote lump formation. Cohesional forces increase with reduced distance between the particles and become prominent in the powder cake, which is usually a result of vibrations experienced by the product during transit or storage. Stresses during storage might induce crystal-form transformations and ultimately alter the reconstitution time (59).

    Treatment of glass vial. Glass vials are sometimes coated internally with a silicone fluid to produce a hydrophobic surface. This operation is usually performed to avoid sticking or adherence of drug to the glass vial, thereby ensuring better reconstitutability (60). However, use of organic cosolvents as diluent must be avoided with siliconized glass vials or stoppers because organic cosolventscan solubilize or extract silicone oil from the package component. The extracted silicone oil can impede the wetting of the affected portions of the cake, resulting in incomplete reconstitution (48).


    Excessive foaming, ie, if you mix bac water in the vial and it foams for say 1-2 hours, that is a sign of degradation and loss of potency

    Likewise if it turns to a "gel" this is also a reconstitution problem and you might want to not use it...








    Purified hormones that have been lyophilized and sealed under vacuum or with dry nitrogen are very stable when stored at or below -15°C, generally showing little loss in activity even after 5 years or more of storage.
