Grapefruit seed extract (GSE) is a naturally sourced preservative with proven anti-bacterial and anti-fungal properties. In may be used in an array of applications including mouthwash, plant spray and cosmetic preservation. GSE is used in food and cosmetics, for skin care, animal health and surface cleaning. Grapefruit seed extract is also non-toxic, environmentally safe, and quickly bio-degradable.
And:
Grapefruit Seed Extract is derived from the seeds and membrane portion of the grapefruit. It is reputed to be an effective broad spectrum anti-microbial properties. Specifically, Grapefruit Seed Extract has demonstrated its ability to kill or inhibit the growth of a wide array of potentially harmful bacteria, fungi, viruses and protozoan parasites. It has become increasingly popular in manufacturing circles as a natural preservative, though it is important to note that Grapefruit Seed Extract is not in itself a full-spectrum preservative.
Unfortunately, that still doesn’t solve the problem, and the author uses some very assumptive words (“proven, reputed, demonstrated”) without citing sources. You can have a liter of the most powerful anti-bacterial/anti-fungal agent known to man, but it will become contaminated and unsanitary given enough time. Unless GSE contains an agent that is able to replicate and continue eliminating the foreign bodies (which themselves do reproduce), then the oil cannot be stored indefinitely. It’s used as a natural preservative, but I would hesitate to praise it as being a good one. One contradiction I spot is saying it can preserve something “indefinitely” and then stating the fact that it’s “quickly bio-degradable.”
I think they’re arguing that it can preserve oil (which already has a very long shelf life) for a considerable amount of time longer than it naturally would. And since most people interested in brewing something likely wouldn’t leave it sitting on a shelf for 5+ years, the longevity surpasses practicality. In other words, “It preserves it longer than what it really matters.”

And this is why the peeps sing your praises. Good stuff, Contrl.

From my understanding a powder shipment that is under the 30 gram mark will make it through quite often, if not almost all the time.
I know a friend ordering some from a new source in the very near future and I would be more than happy to keep you posted on the success rate.
As did a friend of mine, also. 31g, to be exact. I would need to verify this, but I was told the same - that 30g and under isn’t checked at all. Damn that 1g of anastrozole!
How could they possibly have the time? Customs would be checking nearly everything! Oh well, time will tell…[/quote]
I found this in the Canada Customs Act,
"Exception for mail
99(2) An officer may not open or cause to be opened any mail that is being imported or exported and that weighs thirty grams or less unless the person to whom it is addressed consents or the person who sent it has completed and attached to the mail a label in accordance with article RE 601 of the Letter Post Regulations of the Universal Postal Convention."

I think that Bushy hit the nail on the head here. What should concern us about storing oils for long periods of time are “Free Fatty Acids”. A higher FFA count is typically an indicator of rancidity. Some things that you could do to preserve the length of storage time for oil would include limiting exposure to light, and keeping it as consistantly cool (not cold) as possible. Major temperature fluctuations and exposure to light will limit the length of time you could keep your oil “fresh”.

But, when all is said and done, BA doesn’t go ‘off’ and nor do hormone powders. All one needs to do is brew enough for current use, and then brew again as needed.

I’ve been wondering about this a bit, the powder form probably stores pretty well for longer periods of time but does it change for substances that are in a mushy or more liquidy form in room temperature?
