To begin with:
I do not recall declaring a shelf-life for my products.
I have told many people that I personally use some things from over a year ago; but I have never “declared” anything of the sort. These drugs are illegal and prepared by a guy that makes a living in a different field. I haven't and won't declare any sort of shelf life on anything.
I think some common knowledge would apply to most things, such as: If you leave it in the truck in July; it's probably not good anymore---- If it is growing mold; don't drink it.---- If you bought it a year ago and feel sketchy about using it; don't use it. I don't know if a lot of guys that buy these things do so to stockpile for Armageddon; but if that is the case----- I have no recommendations.
Please forward me the information of these PED medications that are reduced to 60% efficacy by suspension. I have not found this in hours of exhaustive searching; and the information would be vital to my work on this.
The suspending vehicle I use is a commercially prepared formulation from a regional pharmacy supply company. I would assume it is very similar to the Humco and Ora brands. I know that the suspending agents in the vehicle are: microcystalline cellulose, carboxymethylcellulose, xanthan gum, and caragenan. It is slightly acidic with pH of 5 and is stable at ambient temperature of ~70 degrees F.
There is limited information available about suspension for many APIs. It has been documented that the following APIs were tested in suspension at 90 days; and at least 90% of the API was detected by HPLC:
oxandrolone
tamoxifen
sildenafil
tadalafil
letrozole
anastrozole
raloxifene
stanozolol (aqueous suspension).
All of these, with the exception of stanozolol, were extemporaneously compounded in a vehicle nearly identical to the one I use.
It is my assumption that other steroid hormones would behave similarly to oxandrolone since they share some common solvents and chemical/physical properties; but there is no high quality data regarding this assumption. I suspect that is because the use of oxymetholone and metandienone is relatively rare in human medicine any more; and some of the chemicals we use were never intended for humans to begin with.
With that said; I have had no doubts about their efficacy in the time period that I have used them.
The common precaution I have found regarding hormone degradation is regarding light: not pH or temperature.
As with everything else, recommendations change frequently. There is a guide on the USP website with new blanket recommendations from 2019. These recommendations do not align with what I have experienced in my personal use; nor do they align with the literature from the tests that have been performed on the above listed compounds.

The short version of my stance on it is: 1) there is no literature supporting degradation in suspension of the APIs that I offer in suspension; and 2) I do not intend to make batches large enough that I would question their efficacy for months after I sell them.
I, personally, would not use a 3 year old suspension or tablet/capsule.
In the end, I make absolutely no declarations of the long-term storage and efficacy of anything I offer. I do still use things I made in 2017 with good results; but that is a personal experience story; not an advisement or declaration of shelf life.
