shelf life after opening

[AnabolicAnimal]

i know the shelf life of most gear is around 2 years or so, but would opening the bottle drastically reduce the shelf life? i plan on buying a 50ML bottle of tren enanthate and only using 1/2 the bottle now and the other half 9 months later. Anyone got any ideas about this.

The only way it would reduce the shelf life, is if you left the cap off, here's something that might give you a little piece of mind, buy another vial (empty) and split the bottle up so your not poking to many holes in the rubber stopper of the vial your gonna keep

Just try to keep it at a reasonable temp and out of sunlight and that will keep it from degrading for the 9 months.
