Heart rate on Reta

[BNLFL]

A pulse ox or a fitness tracker ring like Oura?

No sir, Sleep Number mattress. Like I said, I didn't know it had this, and no way I trust the data. Sucker sure is comfy. We've had it since the end of February.

Ah, I have one like that, finger.

Yeah I wouldn’t want to sleep in that

Here’s mine:

One of my good friends has something like that. Have a link? I'm kind of curious now.

Whoa, that’s a crazy low RHR

And yes, your impression is accurate.

Yeah, generally speaking, Reta increases caffeine sensitivity in relation to elevating heart rate for many.

Does this mean we should go easy or even skip pre workout with high caffeine if on reta?

Thanks, those things aren't cheap. I'm going to do research though.

my resting HR was up12-15bpm when i started, its still up 5 now.

I think that’s a personal feel-it-out situation, but definitely don’t be surprised if you feel your heart pump a little faster than usual.

There are other brands that cost less, the Oura also has a ~$6/month subscription for some features. There are YouTube videos doing comparisons of a variety of the offerings.

Overall, it’s worth it to me, but that’s an individual decision.

Good to hear it dropped for you! Mine is up 7-9 on 2mg.

When read about side effects, found out many users report a heart rate increase. I'm completely on the contrary. Just started Reta recently and I'm after 2 shots of 1mg so far. Before Reta my BPM while doing cardio was around 160-170. Currently it's more like 130-140. Anyone else did notice such a change in a heart rate or is it just me?

Im extremely active pal. Reta has had roughly no impact on my RHR, here is proof: https://cryptpad.fr/sheet/#/2/sheet/view/-5RTrH4QMn1j3eJjdeFrXYVi0E1JzZbFhwEX8Xc7IDc/

My active heart rate i would estimate has fallen about 7-10 from peak before reta, BUT i want to caution this with stating that im simply much more fit now than i was when i started. my BF dropped a couply percent down into 11% range and I simply train harder than I once did

Yeah, Oura ring is expensive, plus you need a membership. I have one, only because when I purchased the 2nd gen, they were giving out free life-time membership. I had quite a few ads popping about other smart rings that were much cheaper, but I have no idea how they compare.

With a heart condition why take Reta? Tirz has nearly the same benefits without the increase heart rate pressure. Curious why you decided reta was worth it over tirz.

Maybe it's ignorance, or that im 41 and still think im bullet proof. The increase hasn't been anything that I think is worrisome.

If you're experiencing higher BPM, Taurine helps bring that down. It's what they put in energy drinks, so your heart doesn't pound so much. Dirt cheap, even Nutricost has a decent product and I take 4,000mg a day.

AI:Taurine is a conditionally essential amino acid supporting heart health, exercise performance, and nerve function, found naturally in meat and seafood. It acts as an antioxidant and aids in cellular electrolyte balance. Widely used in energy drinks, it is deemed safe at 500–6,000 mg daily, although it may interact with blood pressure medications.

My heart was skipping beats a lot at the beginning it has resolved. I am on 7 mg week now

Ideally it is something you should discuss with your cardiologist. Being 41 does not make you immortal or immune to out of control arrythmias, especially if you have afib. Given the lack of studies on reta in cardiovascular disease, and the fact that it increases heart rate more than tirz, tirz would probably be a safer choice. Because reta is not out yet there is no guidance yet on its use in situations where increased heart rate might be a problem. It is likely that reta will also reduce long term cardiovascular risk , like tirz or sema, but it is far from proven yet and there is zero info I know of about risks in established cardiovascular disease, especially given its tendency to increase heart rate more than the other GLP's, so the risks are likely to be more than zero, especially given the anecdotal reports online of large increases in heart rate on occasion.

I'm on two low dose Metoprolol and Lisinipril from when I was in the hospital 3.5 years ago. A bad case of double Pneumonia put my heart in afib. It's never come back since and my cardiologist wants me to stay on it. I was just there two weeks ago for my yearly check up, and all good on everything and the EKG. They don't bother me at all. I'm on Reta since the first of the year.

I have observed increase in both resting HR and Max HR while on Retatrutide. The interesting thing is that I do not feel it at all, either during activity or afterwards.

I did a 25 mile mtb ride yesterday, max HR hit 208 (I am 53). Not having a cardiologist on speed dial, I went to Claude, uploaded my ride details and asked it to pinpoint concern as this was the 3rd time seeing numbers like this since I started taking Reta.

I then entered details about my peps and other meds.

This is what it kicked out.

And yes, I do plan to speak with my Dr.

Heart Rate Concerns — Resolved

Initial concern about 208 bpm at age 53 was systematically explained:

• Age-predicted max HR formula (220 - age) gives 167 bpm for a 53-year-old — making 208 appear alarming on the surface

• Retatrutide (GLP-1 agonist) has caused a uniform +15-20 bpm shift across your entire HR range

• Resting HR moved from 51 → 67 bpm

• Observed max moved from 185 → 208 bpm

• The shift is proportional and consistent — a pathological cause would be erratic, not uniform

• Cialis (vasodilator) likely contributes modestly by lowering blood pressure during exertion, causing compensatory HR elevation

• Feeling completely normal during and 3 hours post-ride essentially rules out an acute cardiac event

• Action item: Inform your prescribing doctor of the +16 bpm resting HR rise to ensure it’s stable and the medication combination is appropriately monitored

A 16 bpm rise in resting HR and a 23 bpm rise in max HR since starting the medications is remarkably consistent. It’s essentially a uniform upward shift across your entire HR range — exactly what you’d expect from GLP-1 receptor agonist effects rather than anything pathological. If it were a cardiac problem you’d expect an erratic, unpredictable pattern — not a clean, proportional shift.
