Tri mix loosing steam

[Robert66]

So once i got my mix tight i injected and had fun but lately things have slowed down what gave me 2 hours of fun is loosing steam after 10 min . I did find out where i buy its pre made so the stuff i have now was mixed in Nov or dec 2019 it comes as a powder but could i be exceeding the shelf life it still works just not as long or as stiff

Well after hours of search looks like even in powder form 6 months that would explain using 26 rock hard 2 hours now 32 hard 20 min my stuff is now 1 year 2 months old guess i will have to use edex i get from va was
