Reta and Cagri Stack Dosing Side Effects and Fat Loss Results

I had surgery and was off everything for six weeks without dieting, then restarted but still can't move the scale.

They seem different enough that a direct swap isn't straightforward.

In what way are they so different? Both have GLP-1 and GIP activity.

Really? What makes them that different?

I'd suggest starting around 3-5 mg though Reta isn't the same as tirz.

The added glucagon piece doesn't seem like it would change things that much.

Because it's hitting three receptors instead of two?

It's not just tirzepatide plus glucagon. The ratios and amounts of GLP-1 versus GIP activity are quite different between the two.

That's not what I meant. What's your evidence for the difference?

That's the exact point. Thanks.

I don't see that as actual proof for how to switch or dose between them.

No official conversion charts exist between these. It depends on side effects you had with tirzepatide at current or prior doses. More sides means starting lower. Cardiovascular issues might also call for caution because of bigger heart rate effects with reta. General health and diabetes status matter too. Rough equivalent might be around 8-10 mg. Reta has stronger GLP-1 and weaker GIP so can bring more GI issues. For safety I'd start 6-8 mg but unexpected sides are possible so lower if needed to avoid disruption.

So basically throw all the non-evidence-based guesses in a hat and pick one?

Some interface text about lightbox controls and errors.

That's the kind of thing the Reta-zempic type would claim. You'll probably need to ask in the Retazepatide area for a direct answer.

My estimates were based on the available science.

Whose science exactly?

Without a degree or real expertise in these non-scientific swap protocols it doesn't mean much. Why would anyone treat you as the authority on these protocols?

I saw some YouTube videos and posts saying Reta has more GIP and less GLP while Tirz is the reverse. Just trying to get that clarified.

Not claiming to be a full expert but I have a related degree and have read nearly every GLP-1 paper I could find over years, easily hundreds of hours. So the estimates feel reasonable and grounded in that reading.

I've explained this a few times. All three receptor types play into appetite and weight effects. The binding and downstream signaling is complicated with lots of albumin binding affecting availability. Many online numbers on affinity aren't accurate and most details are in early papers under different names. Spent time sorting through conflicting info. Secondary messengers like beta-arrestin and cAMP drive the outcomes. Tirzepatide was designed with biased agonism on the GLP-1 side.

Thanks for laying that out, I appreciate it.

They're probably just poking at the phrase 'the science' since it often gets used as an appeal to authority without backing. Not saying that's your intent, but it can come across that way to people, like a modern version of 'my dad said so.' You generally seem informed.

Got lucky with no sides at all while titrating up on Reta. Figure my streak will end eventually, and once I begin I'll remember what you suggested. Appreciate you replying.

Running 2.5 Cagri plus 6 mg Reta leaves me with zero interest in food.

It looks like you're asking the majority now? 😉

Couldn't reach Most, so I talked to his sister Some, and she said Most felt that way.

It really does. Though the lab coat avatar probably evens things out.

With a six-day half life, why pin every three days?

It looks like this can ease the negative reactions

Cuts the chance of sides way down. Plenty of folks split it that way, maybe even more than the once-weekly group.
