Not in the competitive bodybuilding world. If you follow high level bodybuilding and even competitive bodybuilding forums, most if not everyone is still using the traditional staples. No one in their right mind is going to gamble with untested compounds for their preps yet.
I think it will take time before they can fully realize the reliability of glps.
I agree with you, it will take time to fully exploit the properties of GLPs in serious endeavors like competition. There's so much in the way of life extending benefits of GLPs I believe eventually, if the promised months, or even year long versions of these hormones become available, most of the population will be given a baseline dose as preventative medicine like common vaccines, and the "short acting" versions like Sema and Tirz may become PEDs so they can be easily tweaked up and down to exploit properties that Clen and T3 are used for now, with fewer downsides, which I'll explain below.
yeah dont GLPs just increase the time food is in the gut?
That sounds not ideal at all, and any long term effects that reduce appetitte/food absorption are not worth the risk. Digestive issues have retired many bodybuilders.
The purpose of Clen and T3 are to burn extra calories (through numerous processes), I often hear 300-400 referred to by BB experts, to assist you in being in a calorie deficit, and to shift more of the resulting loss from your calorie deficit to fat via lipolysis (clen acts directly on fat cells to encourage that) instead of muscle (which T3 can worsen).
GLP also enhances lipolysis by acting directly on fat cells, even at low doses not used for appetite suppression. A carefully calibrated dose above that level could provide just enough appetite suppression to assist in replicating the 300-400 calorie deficit provided by Clen and T3, or more, or less as needed. And unlike Clen, could be maintained indefinitely, without requiring a break to regain all the extra calorie burn.
Obviously it's going to take a long time, much more data, and a lot of experimentation to get there. But for the casual fitness enthusiast looking for help in achieving a calorie deficit and boosting lipolysis, I think a GLP is a safer option that can be equally effective.
I don't want to make this longer than it already is, but add qualities like GLPs ability to make blood vessels more "non-stick" to plaque buildup, and the amazing discovery it can slow, stop, and even reverse dangerous heart remodeling, *especially* effective in fit people, it's something that mitigates the main hazards of AAS use too.
