Storing Retatrutide

[1939499]

I’m on week two of using Retatrutide. So i only bought a single vial. I’m fairly new to the peptide world. This question might be dumb but I’ve been looking for answers and I haven’t been able to get one. I’m looking to buy my first kit but I’m not sure how the storage would go.

1. Should I reconstitute all the vials and store them in the fridge? They would be 10 mg vials while taking 4mg a week so each bottle should last me around 2 weeks and a half.
2. Or should I just reconstitute them as I go and keep the vials that I’m not using yet in a dark place like in a drawer.

I don’t want to risk them losing their potency. I have seen that a reconstituted vial can last up to 7 weeks in the fridge but I’m not sure about the powder form (prior to being reconstituted)

as you go

Powder form, stored in a freezer that doesn't have auto-defrost, can last many many years. Like 3+ confirmed, and more likely 10 years unconfirmed.

I'd

1. store the bulk of the un-reconstituted vials in the freezer. Many say that modern self-defrost freezer sections. doesn't cause huge temp fluctuations, but you can put them in a thermal bag with an icepack as cheap insurance
2. reconstitute four vials at a time and move them to the fridge, for convenience. Most/many people on here consider them good for 3 months that way, assuming proper bac water and good sanitary practices when reconstituting and when drawing dose.
3. Alternatively, and this is what I'll be doing from now on, reconstitute the whole kit, and then keep all but the active-use one in the freezer; active-use one moved to the fridge 24 hours prior to first use and then kept in the fridge until finished. [A Janoshik lab study commissioned by the super-secret peptides testing group found that repeated freeze-thaw cycles caused minimal degradation to a sample of reconstituted tirzepatide.]

That's for tirz... I was under the impression reta was marginally more fragile? I'd be comfortable doing that with tirz as long as there was room for the expansion of the ice so the vial wouldnt break, but I haven't heard/seen anything similar for reta yet. I'd just keep reta in cake form frozen.

I discussed with a testing server admin replicating the tirz feeeze/thaw test for reta, sema and cagri. I'll probably formally propose reta when my currently-proposed test (LSPL reta 30) moves along.

I disagree with this chart. PGB is currently selling Reta that was manufactured in August-24 and has been stored at room temp the entire time with no degradation.

Short term <1 year - room temp is fine, many store at room temp longer
1-3 years - refrigerator
3-5 years - negative 20C freezer
>5 years - negative 80C freezer

There is debate on the big testing server whether the typical household freezer provides any better results than just storing in the fridge.

I personally store almost all of my lyophilized peps in an insulated storage container in a -20C manual defrost freezer. ($200 Amazon special)
