I remember some prohormones used to have nasal delivery systems. I think they called it cyclo delivery
They did have some products out, it didnt do well..
There's been a ton of devilry methods that are actually very old but are now taking way to larger use in treatments.. From needless jet injections, from patches,gels,creams, and even pellets under the skin, all these applications are older than people think.. The nasal application isn't practical and is actually be discontinued in TRT treatments, it causes way to much irritation.. It still needs to be used daily and like any other application it will still take time to see effects as levels need to build.. There's no intimidate effect right away, steroids don't work like that..
I do know that they plan on keeping it around for anxiety meds and pain medication treatments because of the fast responses with these medications, but hormonal it has no benefits... Now if we're talking steroidal for sinus treatment and allergies, they will still use them, but even at that applications with the disadvantages far out-way the advantages and positive effects.. Irritation is a major issue
Tren Base if the way to go people for fast action, but even that, it's a placebo at first and takes time to build up..
