STOCK UP: Don't say you weren't warned! (US)

IMO, it's time to stock up on peptides.

If you're really serious, get a small cryofreezer so they'll have an effectively unlimited shelf life.

I was hoping peptides, as they fall through a legal loophole (except HGH), would be spared from the imminent de minimus crackdown. But the mountain of money on the line and end of legal compounded alternatives means big pharma has a new target to focus on, and non-GLP peptides will almost certainly be collateral damage.

These organizations have a nearly unlimited war chest of cash, and significant political influence already. The fact their interests align with what's already in motion makes it a near certainty in my opinion.

Did you end up getting one of those small freezers? Been eyeballing them because why not

Yeah I bought a this model of Stirling used on eBay, There are plenty for sale, When they decommission ambulances they don't transfer equipment to the new ones so many of these freezers become available. I paid $900, a few scratches but it's built as well as you'd expect a portable cooler that sells new for $8000 would be.

I love it. It's light, takes up very little space, once it reaches temp it's very quiet, and the insulation is outstanding so electric use is minimal (it can run directly off 12v as well as 120v AC). Temp is spot on at -122f .

I took up the empty space with solid freezer packs.

What containment do you store your peptides in while in the freezer, what temperature and what process do you recommend when removing from for use. Like do you you place in refrigerator to allow a slow temperature aclamation.

Also thanks for sharing this units availability!

Right now I'm using the same plastic cases with foam inserts I've always used, but this is far from ideal. At these temps, the plastic and foam become so brittle that even with gentle handling they're cracking and won't last long.

Besides the question of durability, the other factor I'm keeping in mind is exactly what you mentioned, The effect of temperature "shock" on the condition of stored peptides.

TLDR you want to freeze rapidly, -1c/minute, to prevent the formation of peptide damaging large crystals in whatever moisture content is present, and thaw slowly, to minimize mechanical stress on the proteins as they warm up and expand.

After digging into the methods used in labs handling proteins, this is best accomplished with alcohol filled cryo containers. I'm still looking for a model that will hold 3ml peptide vials. Most are designed for 2ml (or 5ml) vials. They may be compatible but so far I haven't been able to verify.


I only recently got the freezer, so I'm still working out best practices, but for now, two days before I need the vials, I transfer to the (regular) freezer for a couple of hours, then into the refrigerator.

Thanks for the feedback good man, would you share the ebay link as I've only been able to find that unit and a higher price.

Search for "Stirling Ultra", and regardless of asking price, make an initial $800 offer, and try to strike the best deal from there. I was prepared to go to $1500 if necessary, and whether I got unsually lucky or not I can't say since I only bought the one. But I'd expect you should be able to get close to my price.

The Chinese knockoffs are around $1200 (or less), so anything less than that for one of these is a bargain.

Thanks for the info, grabbed one earlier today :-)
 
New member i have packs being held for inspection since 12-16
Sorry i cant seem to use my bitcoin for full access

Technically US customs can detain for inspection for a month, so until 30 days have passed they're not necessarily seized. I've gotten packs after being detained by customs for 6 weeks.
