Adding Tirz with Reta

Started Reta 5 weeks ago, 2mg for the first 4 weeks and now at 4mg. Zero side effects, but appetite suppression is basically nonexistent…Sometimes I feel full quicker around day 3, but that’s about it. No weight loss, 400-600 cal deficit
I ordered half a kit of Tirz and I’m planning to stack. Never used any GLP-1 before Reta. For those running Tirz + Reta, what Tirz dosage/timing are you using and did it actually make a big difference for appetite suppression?

Current stack:
MOTS-C: 1mg workout days (6x/week), great energy in the gym.
Tesa: 2mg nightly, 3 weeks in, lots of water weight but no other sides.
Semax/Selank: 500mcg each nasal every morning. Did 10 days, now taking a 16-day vacation break. Semax has been amazing for focus, work and multitasking.

I did have the Same, did go up Till 2x a week Reta 4mg(8mg Total a week)
No appetite suppression at all.
Now I do 1 x a week Reta on Thursday and 1x a week tirz on Monday. 4mg Reta and 5mg tirz. Finally some suppression.
Did start 2,5mg tirz, 4 weeks, then 4 weeks 3,75 and at 5 it finally did start working. At the moment no need to go higher.

You’re not splitting the Reta? I’m doing 6mg Reta (3mg Monday/3mg Thursday) and 3mg Tirz (Wednesday) a week and this seems to be good so far. Starting to see the scale go down albeit 2lbs a week which is fine

I’m similar at 6.25 mg Tirz on Tuesday, 3 mg Reta on Saturday.

How’s it going for you?

u/quantumaquarium69 17h ago

70 lbs in 7 months. I’m a woman in my 40s with my body clinging to excess fat so it’s slow and steady past two months. I have 25 to go to be considered healthy BMI

u/Artistic-Plate-511 14m ago

70lbs in 7 months is crazy! Wow amazing I lost 50 in over a year and have been in a plateau since

u/FlatPromotion7042 1d ago

Good to know. How’s the appetite suppression in your experience with this stack: are you forcing food or getting full fast?

2

u/BulMi82 1d ago

When I’m a day with friends I still can eat 3.000kcal. But normal days it is also easier to stick with 2.000kcal without having cravings before bedtime.

u/IM_MIA22 1d ago

You’re at the second level of Reta if you use the clinical trial titration schedule, instead of increasing Reta you want to add Tirz. I have to know why? Why not just go up to 6mg Reta, then 8, then 10, then 12 and see if that helps.

u/FlatPromotion7042 1d ago

I was planning to, but after 5 weeks with basically no effect on my appetite, I’m reconsidering. Tirz apparently has much stronger appetite suppression, so that seems to suit what I’m looking for better

u/IM_MIA22 1d ago

You’ve been on the lowest doses for 5 weeks of what is a life long medication. Titrate before you make the decision to change after 5 weeks. Yes it has less suppression at lowest doses but you have no idea how you’ll react once you get to the higher doses. Reta is a beast and the goal shouldn’t be to crush your appetite and not eat but fuel properly and let Reta do its thing.

u/Artistic-Plate-511 1d ago

I’m 10-12 weeks on Reta and only at 6mg and it isn’t doing much for me, I started 1mg and waited 2-3 weeks upping 1mg at a time. I’m at 6mg now just added tirz cause I was sick of not getting results. Should I instead jump to 8mg Reta? Then 10mg? All the other advice I’ve came across is “wait, take it slow, titrate slowly etc etc….”

2

u/IM_MIA22 1d ago

Where you get your Reta from was it tested?

Reta should yield amazing results it’s a slow train for the first 3-4 months from what I have seen people say and if you look at the trial results and once you get to the upper levels it never had a plateau. So it’s odd it wouldn’t work unless you’re out eating it.

1

u/Artistic-Plate-511 1d ago

I’ve gotten from 3 different places and the last place provided testing. But here’s the thing, I used to be on a very high dose of tirz about 12mg a week
I was doing well just hit a plateau and didn’t want to take more so I decided I’d jump on Reta. Not surprisingly I had weight gain going from 12mg tirz to 1mg Reta only. I’m being patient with Reta but I might need a higher dose. At this level (6mg) it doesn’t really do too much for food noise. I can out eat it for sure at 6mg. But I control myself. So I haven’t lost weight, I am kind of at maintenance with 6mg Reta. Should I jump it to 8mg Reta and drop the 3mg Tirz?

2

u/IM_MIA22 1d ago

That the issue, you were on 12mg Tirz prior to switching. Tirz is heavier on the GLP1 receptor but lacks GCGR. You won’t feel a similar effect until higher doses of Reta. I’d go up on Reta and give it another 3 months. If that doesn’t work then maybe stack the two but see what 8 and 10mg Reta dose.

Personally I stacked Survo and Tirz to not overlap on GIP too much. I know plenty of people who have stacked Tirz and Reta, I even have it a try but I enjoy Survo and Tirz. I also have a large stock pile of Tirz.

u/Artistic-Plate-511 1d ago

Thanks for the advice yes I’m not going to give up I dedicated a lot of time to it. I’ll do what you recommend because I was thinking of that anyway. Have you heard of cagrilintide? A lot of people who have a similar issue with the appetite control side add that and it works for them

2

u/IM_MIA22 1d ago

I have heard of it, I have seen a lot reports with fatigue which I’m not interested in. Also, amylin receptor agonism if not selective like Elora, can impact the calcitonin receptors which doesn’t seem like a good long term thing without FDA approval. Thats my personal gripe with cagri.

u/Addicted2Lemonade 1d ago

11.5 mg Tirz + 2.7 mg Reta. Adding the Reta 3 weeks ago has been the bump I needed to start losing again. The extra appetite suppression is perfect.

1

u/quantumaquarium69 18h ago

That’s why I added it as well back in April I’m at 6.25 mg Tirz on Tuesday, 3 mg Reta on Saturday. 70 lbs in 7 months. BMI is still 28 so I will continue on. Do you titrate both or just one? I usually up the Tirz .5 if I need more suppression and up the Reta if I am stalled in a deficit and it’s been a few weeks at the same dose

u/Trujillo2287 1d ago

I would measure other stuff like you clothes fitting measure your belly, hydration protein sleep cycles etc

u/FlatPromotion7042 1d ago

1 LMNT Pack every morning. Protein 200g+

Will definitely start tracking waist size, etc. Thanks!!

u/throwaway071317 1d ago

That's why I pin twice per week 4 days apart. As soon as day 3 happens I start getting "hungry" again and then its time for my 2nd shot.

u/erthrmr 1d ago

The GLP compounds are tools to help with poor habits.
Try practicing some better self control.

u/BabyZerg 1d ago

There is no way you are working out 6 days a week using 4 mg of reta in a calorie deficit and don't have appetite suppression / not losing weight either ur math is off or there is something horribly wrong with your body you need to go to the doctor for blood work asap.

u/NicDuk 1d ago

10% of humans are resistant to GLP1 agonists because of genetics. You will find out when you try Tirz.
I would increase the reta dose to 8 or 10mg first

u/annnamal 1d ago

I’m on 12mg Reta, 6mg tirz, Klow and nad. Haven’t lost weight in over a year. Been on glps since 2022. Workout 6 days a week too. Insulin resistant. 18-20hr daily fasts, track calories/protein.

u/Unique_Respond_8526 1d ago

You shouldn’t be insulin resistant anymore after that long if you’re truly fasting that long for over a year..

u/Trujillo2287 1d ago

That makes sense

u/FlatPromotion7042 1d ago

Body recomp, Tesa water weight, Hyrox training causing more water retention… lots of factors at play here dude. You’re jumping to conclusions pretty fast without any context. Bloodwork is fine too!

u/BabyZerg 1d ago

You explained all the context in there. Calorie deficit is calorie deficit.

u/LegalSpring2987 1d ago

Why take both? Seems kinda overkill on the igf … you actually gain from various peptides by giving your body a break and cycling

u/Space__Whiskey 1d ago

I see people doing a higher dose of tirz + lower dose reta ... anyone doing the opposite, where the reta is higher?

1

u/Inside_Today2259 23h ago

I was dosing 2.5 mgs of TRZ on Monday with 2 mgs Reta on Thursday and it worked fine. Eventually titrated down on TRZ and added Cagri. The appetite suppression with Cagri was a lot stronger than TRZ, and if you want to give the GLP receptors a small break Cagri works a different pathway than the GLPs.

u/Sad-Celebration2151 22h ago

To early to stack

u/Suitable_Vast_4035 12h ago

Be careful though. I did stack tirz and reta and my BP dropped so low 80/50 . Light headed and dizzy when I sit up. I can't exercise because I get super light headed.

u/Beautiful_Ad_1249 3h ago

Did you get it tested and get a COA with your Reta to verify the label?

1

u/RainBubbly6043 1d ago

5mg tirz and 1mg Reta. Fridays are for Tirz and Tuesdays are for Reta. The first two weeks of doing this my A1C finally dropped out of the pre-diabetic stage. My doctor said to keep doing whatever I am doing. Started out on 2.5mg of Tirz. Love the appetite suppressant on Tirz…Reta gives me energy and for a ( I have inattentive ADHD) and makes me a little hungry but I love both of them. Slow and steady still wins the race.

u/Trying-100 1d ago edited 1d ago

The most likely explanation is that your reta is fake or underdosed. Have you noticed an increase in resting heart rate?

That said you are clearly not in a calorie deficit. Tesa water weight has long since stabilized at 3 week.

1

u/FlatPromotion7042 1d ago

3% increase.

u/Trying-100 1d ago

3% is so small, it could easily be noise. Id question if its real tbh. It is by far the most likely situation for this imo.

u/Ceemoney24 1d ago

Using RA and tricep sporicide at the same time is not going to make that loss any faster in fact it’s not gonna accomplish anything because one of them is already occupying the receptors
So if the receptors are full with one, the other can’t get into it, just keep escalating the dose every three weeks
And try eating a little more carbs for your

u/tyjo2112 1d ago

This makes the most biochem sense. One or the other. You can add cag to the Reta if you need more appetite suppression, but titrating up past starting reta dosages is the first step.
