r/GLP1microdosing

My experience with microdosing tirzepatide so far!!

Just wanted to share my experience with microdosing tirzepatide so far!!

I'm totally new to the GLP-1, and am trying to lose a few pounds. My biggest reason isn't even just the weight loss, its the food noise. I felt like I was always thinking about food and dealing with cravings, even when I wasn't actually hungry. Dieting was really hard for me because of that.

I did a lot of research and ended up going with Fridays because the reviews were pretty good and it fit my budget. I was originally going to go with Noom, but they offered me a really low-dose plan. Apparently this is a new plan they have? and from what I understood you can't change it. Since it was also more expensive, it just didn't seem worth it to me. I was also looking for a provider that would be okay with prescribing a microdose since a lot of them have BMI requirements.

For anyone wondering, I ordered on 6/24 and my vial arrived on 6/26, which was pretty fast. You inject once a week, and I've only done two injections so far, so I obviously can't speak on long-term results yet.

So far I haven't had any side effects (at least for now lol). During my consultation, the doctor did tell me that side effects are pretty uncommon at a microdose.

I noticed the appetite suppression the day after my first shot. The biggest thing I've noticed is that I get full way faster, and I don't think about food nearly as much. I still get cravings sometimes, but they either go away pretty quickly or I'm happy with a small portion instead of wanting to keep eating.

Overall I'm really happy with how it's going so far. I figured I'd post this in case anyone else is in the same boat I was!

Happy to answer any questions!!!! I also have a referral code if anyone needs it. I actually used someone else's referral code lol, so my first month ended up being $78.

When did it kick in?

Hello everyone,

This morning (about 9 hours ago), I took my very first dose of Mounjaro/tirzepatide - 1 mg. I decided to try microdosing since I only have around 6–7 kg (13–15 lbs) to lose.

It’s still too early to tell if anything has changed. After the injection, I had a light breakfast, and a few hours later I got really hungry (probably because I went for a morning run). I ended up having a big lunch with a friend, including dessert. So far, I haven’t noticed any appetite suppression at all.
That said, I know it’s very early, so I’m not jumping to any conclusions yet.

What was your experience like? When did you first feel it kick in? I know everyone responds differently, but I’m curious to hear your stories. Thank you!

.1mg microdose 2x week question

Hi! I started with .1 mg once a week and then upped to twice a week however, on the 2nd week of 2 injections, I got so nauseous and dizzy the day after my 2nd injection that I was in bed for 1 full day and still feeling ill a 2nd day. I was also cycling 10-15 miles a day, so I am not sure if I had heat exhaustion with the high temps we've had in the midwest, or if it was from the 2nd dose that 2nd week week. Has anyone else experienced this? I really think it was from heat exhaustion, but now I'm nervous to go back to 2 doses a week. I will definitely discuss with my Dr at my next visit, but I wanted to know now if others have had this happen as well.

GLP-1RA and the possible skin aging

This review looks at what we keep seeing (Ozempic face) and investigates whether it's a result of rapid fat loss or could GLP-1 rector agonists directly accelerate aging. The authors actually conclude that both may be true. And ironically, they also have research showing they have anti-aging effects on other parts of the body by reducing inflammation and oxidative stress. They examine whether mechanisms beyond fat loss may contribute to skin aging during GLP-1 therapy. Skin aging is characterized by reduced mitotic activity, impaired skin barrier function, decreased collagen and elastin product, diminished cellular proliferation, increased apoptosis, and elevated oxidative stress. Increased production of reactive oxygen stress damages DNA and cellular membranes, activates signaling pathways that reduce pro collagen synthesis, and stimulates inflammatory pathways involved in collagen metabolism.

GLP-1s have proven research on type 2 diabetes, obesity, and weight loss, but they also have demonstrated anti-inflammatory effects have been investigated for skin diseases. As their use has increased, so has facial aging associated with significant weight loss been noticed. The change is usually connected to the loss of facial fat because it alters facial contours and results in excess skin, more visible wrinkles, and changes in facial proportions. The authors note that this phenomenon is not unique to GLP-1s though, and has also been described following bariatric surgery. Histological studies of patients with major weight loss have demonstrated alterations in dermal structure, including changes in collagen and elastic fiber density.

The authors describe evidence suggesting that GLP-1s may influence dermal white adipose tissue (DWAT) and adipose-derived stem cells (ADSCs). These both express GLP-1 receptors. DWAT contribute to skin maintenance and regeneration and reduced DWAT has been associated with aging skin, decreased collagen production, and increased activity of an enzyme involved in collagen degradation (matrix metalloproteinase-1.) Studies show that GLP-1 receptors on ASDCs may decrease the production of protective cytokines and growth factors, impair fibroblast migration and collagen synthesis, and increase oxidative stress within the cells. There's also a lot more interesting in the weeds findings, but don't want this to get crazy long. They touch on estrogen receptors, muscle loss, etc.

The authors ALSO found evidence suggesting that GLP-1RAs may have effects that support skin health too. It reduces chronic inflammation and lower concentrations of AGEs. They also associate this with reduction of blood glucose levels. There are various studies touching on this as well. The authors also found from other studies that GLP-1s improve endothelial function and increase microvascular perfusion within the skin and subcutaneous tissue. But they note that no published study has directly linked these effects to delay skin aging yet and state additional research is needed.

The point of this review is that it argues Ozempic face is way more complex than simply losing facial fat, but there is currently still not enough evidence that GLP-1s directly age the skin. Please do not take this as discouragement from using them or as fear mongering. I want people to know the science of what could be going on. Keep in mind that this is a mini review, not a clinical trial. A lot of the mechanisms come from biology research and inferences. But what I would offer from this is. If these mechanisms are happening and you are using them, what would theoretically protect against them? If you're worried about reduced collagen signaling, you would want things that support collagen production. If you're concerned on oxidative stress, you would want to reduce oxidative damage. If it's about the reduced stem cell activity, you want to support tissue repair and regeneration. If you're worried about the loss of dermal estrogen signaling, that is currently being studied in peri and postmenopausal research. This paper to me actually is something that can be used on future research on how to combat these things.

GLP-1 Has Reduced My Drinking, but Alcohol Hits Me Much Harder Now

I’ve been on a GLP-1 medication for eight weeks now and I’m still on the starter dose of 2.5 mg. So far, it has been working really well for me: I’m losing weight, I have much less food noise, and I find it easier to make healthier choices. I’m also going to the gym regularly, so overall I feel like things are moving in the right direction.

One thing I’ve noticed is that it seems to have reduced my alcohol intake too. I used to struggle with binge drinking, and compared with how I used to drink and behave on nights out, I would say my alcohol consumption has probably reduced by around 50%.

At first, it felt like the medication really took away the desire to drink. I just did not feel particularly interested in alcohol. But I’ve realised that when I’m out in certain social situations, there is still a learned habit there: ordering drinks, staying out late, and chasing that buzz. So it has helped, but it definitely has not completely switched that part of me off.

What has surprised and frustrated me is that although I am drinking less, the after-effects seem much worse. For example, last night I went out around midnight and stayed out until 5 a.m. Over those five hours, I had six standard drinks in total: two beers, one shot, one double gin and tonic, and one single gin and tonic.

I went to bed at 5 a.m. and woke up around 10:30 a.m. feeling extremely dizzy, still drunk, nauseous, exhausted, and with a really bad headache. I was so wiped out that I went back to sleep. I spent most of Saturday asleep or dozing on and off, briefly watching YouTube and then falling asleep again. I got up late in the afternoon to eat something, then went straight back to bed and slept through Saturday evening into Sunday.

It genuinely felt as though I had lost an entire day, even though I had only had six drinks. I was invited to a few things on Saturday and had to miss all of them because I felt so awful. It is strange because I am drinking much less than before, but it feels as though alcohol is affecting me far more strongly now.

Has anyone else experienced this on GLP-1 medication? I’m grateful that it has reduced my drinking, but part of me wishes it worked strongly enough that I simply did not want alcohol at all, or that I could comfortably stop after two or three drinks.

I also wonder whether a higher dose would help more with alcohol cravings. At the same time, 2.5 mg is already working for me in terms of weight loss and appetite, so I do not feel like I should increase it just for that reason.

Not overweight, but slowly gaining out of my control - microdose worth it in my context?

For context, I am not overweight. I am 25, 5'5.5" and weigh 150lbs (female), just on the cusp between a normal weight and slightly overweight. Great measurements, 28" waist, so on. Nothing is immediately concerning. I've had a big weight loss (190 to 135 after treating hypothyroidism) before and generally know what I'm doing and it's not working for a few reasons.

Since October, I have gained about 15 pounds eating the same stuff I always do (even cutting back). However, the change is not exactly something within my control. I was diagnosed with a rare heart disease called ARVC in January and had surgery for an ICD implant. I used to be on Vyvanse for ADHD management, but due to this condition I had to stop and was instead put on Metoprolol, which often causes weight gain by changing your metabolism/lowering HR. Absolutely cannot get off Metoprolol or take Vyvanse again, this is critical to management of my disease so I do not die.

My heart irritability/ectopy/PVCs are also contributed to by, you guessed it... hunger/fasting. Dehydration. Electrolytes being off. Ah, wonderful for me.

Worse is that because of my ARVC, I literally cannot exercise like everybody else. Like, legitimately. I can do stuff like normal walking, maybe very light lifting, but my HR isn't supposed to go over 140 or so.

I feel trapped watching the number on the scale slowly go up when there's not much I can do about it aside from eating very little, which only makes my heart (and mind) madder. I do have a PCP who I talked to briefly about regarding this issue and she said if I continue to gain weight she'd be willing to prescribe a GLP-1 because of my unique situation, though it'd obviously not be insurance-covered.

I feel like this is a situation where a bit down the line, if it's not my thyroid causing issues or I can't maintain my weight (though I'd prefer to be 140lb)... GLP-1s and microdosing might be warranted. I absolutely do not have diabetes (A1c is like 5.3, cholesterol good) and am not even overweight and my weight distribution is healthy but I'm terrified of what may come over time if I just let things drift. I do not want to be overweight again. The idea terrifies me, I felt terrible when I was overweight.

How exactly do you guys start with this stuff? Where do you begin? At what point is the microdosing officially considered 'warranted' since I'm not actually overweight yet? I can afford a few hundred dollars per month but I really can't afford thousands monthly and I'd like to avoid large dosing if possible so I don't like... I don't know, barf over literally everything like my dad on Ozempic does.

Thank you guys in advance for your help/suggestions!

0.25 mg tirz

Is anyone holding at 0.25mg? Thinking of doing it just for the inflammation but curious for those running at 0.25mg how many side affects and appetite suppression you get (I’m not looking for any).

If not anyone stay at 0.5 and can share their experience?

Anyone stay on tirzepatide and stop the hair loss with oral minoxidil?

Basically the title. Looking to hear from anyone who successfully stayed on tirzepatide because oral minoxidil eventually stopped/recovered the hair loss.

Specifically, I’m looking to hear from people who had what seemed like drug-induced TE from tirzepatide, not hair loss from rapid weight loss.

My shedding started almost immediately after starting tirzepatide (started at .5 currently only at 1.5mg), and over the last 4 months I’ve lost what feels like half my hair. It’s been pretty devastating.

I started 1.25 mg oral minoxidil 5 weeks ago, but I’m in what I assume is the dread shed, and it’s honestly worse than before.

For those who stayed on tirzepatide while taking oral minoxidil:
\-Did the shedding eventually stop?
\-Did your hair grow back while staying on the medication?
\-Or did you have to stop tirzepatide for things to improve?

Please don’t suggest protein, iron/ferritin, thyroid, or slower weight loss. I’ve already addressed all of those, and I’m specifically looking for experiences with what appears to be tirzepatide-induced TE.
I’d especially love to hear from anyone who was able to stay on tirzepatide and eventually recover their hair with oral minoxidil. ❤️

What are your favorite pen needle length and gauge?

Getting ready to order pen needles for kwikpen on Amazon. There are so many options and I’m showing they all are compatible. So I assume it comes down to preference or maybe you just pick your favorite color 🤣

Which do you prefer and why?

Is there a difference between brands or just size?

Inflammation on Tirzepatide

I'm reducing my tirzepatide dose because I don't like the effects on my heart rate/HRV. My doctor titrated me up to 15mg right away and I don't think that was a good idea for me. I know that I will have to stay on it at some level because it's improved my life so much, but I want to reduce it. I think I can manage my appetite at a micro dose now that I'm in maintenance, but I'm scared of losing the inflammation benefits. Are you guys still having inflammation benefits on a microdose? If yes what dose are you at?

Retatrutide Efficacy ( Weekly injection vs split dosing )

I have been reading certain research saying the efficacy of Glucagon receptor of retatrutide is based on Peaks, unlike the GLP and GIP receptor which depend on concentration and saturation.

Let's say a person decided to take 5mg retatrutide weekly.

Scenario 1: 5mg taken on Monday as a single shot but it leads to a little GI upset.

Scenario 2: Split dosing, 3mg on Monday, 2mg on Friday.
No side effects felt at all.

Main question is, will the split dosing reduce the overall efficacy of the peptide? Moreover, is it actually true that glucagon effects are most pronounced if taken as a single high dose?

Hair loss may be permanent. Make sure you know what kind you have!

This is becoming more well known now but while I was on tirzepitide I experienced hair loss from androgenic alopecia. This is female pattern hair loss and it does not just grow back, and it’s not from rapid weight loss or nutritional deficiencies.

I want people to know so they don’t wait it out as has been suggested by many. If you’re experiencing hair loss while taking this med, go to a derm and get a scope done. Don’t let them just eyeball it. If they can see no miniaturization or scarring at the follicle, they can tell you it’s TE with confidence and then it likely will grow back. which is great news for you! It’s easy to tell when it’s AGA because they will see miniaturized hairs.

but if you’re like me and GLP1 kicked off an underlying predisposition to AGA, then the loss is permanent and progressive without specific treatments. i also made the choice to stop the med. I was on it for 10 months, never went above 2.5mg and lost 13 lbs in that time. No nutritional deficiencies detected in bloodwork I did every 3 months.

I went to a derm early on when I started losing and she said glp1’s dont cause AGA. I went back 8 months in and she said the research now suggests that it can in some people. They didn’t know before. Now they know it can cause AGA but they still don’t totally understand why.

I just want others to know this and get the right treatment so they can make choices while they still have them!

oral birth control

I started microdosing tirzepatide about a month ago. I have slowly worked my way up and am now on 1.25 mg. I have been on oral birth control for > 15 years.

I understand the risk of normal dosing of tirzepatide decreasing efficacy of OCP and increasing chance of pregnancy.

My provider stated 1.25 mg is a low enough dose that I don’t need to worry about back up contraception unless I go up to 2.5 mg. I am getting it through Everwell pharmacy which is accredited so hoping I truly am only getting 1.25 mg.

I am looking for anecdotal experiences for those who microdose, any unexpected pregnancies or signs of decreasing birth control absorption?

Newbie microdose question

Microdosing ???

For those of you using or who tried microdoses of tirzepitide (less than 2.5), how long did you stick with that dose if your body didn’t respond? I’ve heard to stick with a dose for a month before deciding to bump up, but is that time frame reduced if you’re microdosing? Would love to hear others’ experiences.
