I have had some peps in the fridge for about a year now. MGF, GHRP, IGF, HGH frag and was wondering if they are any good?
how long do peps stay good

mixed or unmixed?

Gropep is the company that invented IGF-1 and I refer to there website often for research. You can read more here at GroPep Bioreagents: Biotech Reagents
Below is an insert from there website in particular to storage of peptides you may find informational or informative to your question.
General Precautions:
* Avoid peptide concentrations of less than 1 mg/ml in the absence of carrier protein
* Avoid freeze-thaw cycles
Stability / Storage: Peptides in the lyophilized state should be stored at 2-4° C and are stable for at least 2 years, or 6 months at room temperature¹.
Handling Procedure: GroPep Bioreagents IGF peptides are supplied as lyophilized preparations in glass vials in an atmosphere of nitrogen at a slight vacuum (-25 kPa). To avoid losses care should be taken to equilibrate this vacuum when opening the vial and reconstituting the peptide.
Reconstitution and Stock Solutions: The peptide should be reconstituted in 10 mM HCl at a concentration of 1 mg/ml. In this form it is stable for at least 3 months at -20° C or -80° C¹. Avoid freeze-thaw cycles.

Look forward to your business Mike 
Hi, I really would really appreciate any wisdom or guidance on this issue.
About 15 months ago I ordered 5 vials of l3 IGF-1 powder and 15 MT2, and stored them at room temperature for the first 12 months. After reading that it should be stored in the freezer, I did..after a year at room temp.
I have seen the study posted here on Steroidology, which says it retains potency for 2 years at room temperature and so on & have also seen many posts which suggest it must be refrigerated/frozen or it will degrade in weeks or few months. Here is where it gets confusing for me: I used 1 vial of igf1, when I first got it and noticed ravenous hunger, tighter skin/slightly lower body fat, nearly immediately. About a year later, I started on my 2nd vial and *nothing* has happened after dozens of injections.
I emailed the company I ordered from and asked about potency and they responded:
"MT2 is good for about a month outside of a freezer environment and IGF about 3/4 that time. The worst that happened is the peptide degraded to the point that it doesn't work"
Now I don't know whether to throw out the large stockpile of peptides I have because of my personal experience and what I have read. At the same time I read many posts of those saying they stored at room temp for many months and it still worked. Most of the vials have not been reconstituted also. I am tempted to blow a bunch of money and order it all again & freeze immediately, but there are even posts that say freezing it destroys it because of freeze/thaw cycles in the fridge..would refrigeration be ok? There is so much conflicting information on this, despite this peptide being out for nearly a decade.
I would really appreciate feedback from you! Thanks
