Tesamorelin and other GH Secretagogue dosing protocol

Thanks for that. Yeah the whole 2 day break just keeps on coming back to bro science. But I guess I am going off of my interpretation of similar studies which in itself would also be my own bro science... šŸ˜…
As lessthanhalf laid out upthread, anyone not taking this to offset visceral fat accumulation from HIV meds is already engaging in "bro science," regardless of the number of days a week they're doing it. 🤣 And the same is true of most of the non-GLP peptides being discussed on this site.

It's all competing "bro science" stories arrived at through N=1 trial and error.
 
Just my 2c:
5 days on, 2 days off.
This is quintessential bro science. The 5 days on 2 days off protocol doesn't make sense for any drug, as drugs are not salaried workers. But people working at medical spas are, which is where this protocol comes from - their offices were simply not open on the weekends, and so their patients couldn't come in to get the peptides administered.

All of the human clinical trials of tesamorelin were done in people with HIV lipodystrophy
There is no such thing as "HIV lipodystrophy." The problem Tesamorelin is solving is HIV patients taking antiretroviral HIV drugs which cause an abnormal rise in visceral fat. The significance of HIV in relation to Tesamorelin is just that the older antiretroviral HIV drugs affect visceral fat, it's not the HIV itself which affects it (other than possibly elevated chronic inflammation.)

Wow never thought about that, usually the best answer is the simplest, and this right here might be it.

In the end, until a proper peer reviewed, placebo controlled blind test is done, it is all speculation.
You’re spot on, a lot of this is still speculation. I’d just take it one step further.

For anyone running this, I’d recommend they get baseline labs. IGF-1 and Z-score matter. Otherwise we’re all guessing.

From there, test your approach instead of relying on protocol debates.

Some people are running 2mg, 5 days on / 2 off and if that’s the route people choose to emulate, run it and retest. See what your numbers actually do.

I’ve personally adjusted down to 1mg nightly and plan to retest in a couple of weeks. My goal is to simply land in an effective range without overshooting IGF-1 long term.

I’ll come back and share my results so there’s at least one real data point in here.

Also worth noting as mentioned above the 5/2 split is often framed as cost savings. If 1mg daily keeps labs in range, that stretches a kit even further (100 days vs 70 days) while adding a layer of control.

At the end of the day, your labs > others opinions.
 
I personally love the 5day on 2 day off Tesamoralin schedule. I am quite sensitive to Tesa. After 5 days on 1mg. Tesa I retain on average of 8 lbs water. The 2 days off I piss like crazy!! I don't enjoy the bloated feeling. That's why I take 2 days off. Tessa has been very useful. When I was losing my last 10 lbs on Tirz My muscles were shrinking fast. Tesa 1mg. 5-2 completely reversed that.

I take 300 mcg Ipamorelin with my Tesa but the side effects are from the Tesa. I only use 1mg of Tesa because it raises my resting pulse by 8-10 bpm. at 2mg.

Now that I am at my target weight I use Tesa to counteract Enclomiphene lowering my IGF-1 levels. My labs show 5 on 2 off works great for this too.
Note: I do not have HIV

This is my personal experience with it.
This is anecdotal information. Maybe it is bro science but I doubt it is a placebo effect. There are too many measurable physiological changes.

This is great feedback. Thanks for sharing. I feel your pain on the water retention. I stated Tesa two weeks after Tirz and not only did I gain the weight I lost, I also added more weight then where I started with Tirz.

Again, your labs and individual response is greater than any random protocol being pitched online by strangers. I’m glad this is working for you and congratulations on hitting your goal weight.

You had me worried there for a bit thinking my brain must have made the term up, but after looking through about 10 papers on it I did find a recent one that called it HIV lipodystrophy, rather than abnormal visceral and liver fat accumulation in HIV patients, so it might not be the most common term for it but at least I had not misremembered or made it up.
I did find a study of tesamorelin in diabetics that showed no increase in insulin levels or hb1ac, at doses of 1-2mg / day. It directly contradicts what I said about checking blood sugars, but I do not understand why it would not increase sugars and insulin if it acts to increase HGH and IGF-1.
So maybe it does not have adverse effects on sugars, and if this is actually the case then it does make it a safer option than HGH, but as the mechanism makes sense to increase sugars it is still probably not a bad idea to check them. Nearly everyone taking it is likely to be on reta or tirz which have a much stronger effect on lowering blood sugar than hgh does on increasing it, so not sure how much of an issue it really is in practice.

Maybe because the increase in GH does affect insulin sensitivity negatively, but that might be counteracted by the fact that at the same time Tesamorelin reduces visceral fat which is known to improve insulin sensitivity? Interesting stuff!

I was going to ask why you weren’t at 2mg, glad you answered it. Sounds like you’re still getting good results at 1mg!
 
My admitted very limited understanding of these is that the CJC's and Tesa's are signaling molecules that aid the Pituitary to secrete more GH, so they do not necessarily need to be cycled. The Ipamorelin is different in that it works through the Ghrelin receptor, and so it will end up down regulating this receptor and should be cycled.

Beyond that, there is a reason we call it research. YMWV...

Sermorerlin is milder and would be less risky for the long-term, at least if one naturally has high-normal IGF-1 for one's age. But cost-wise, less bang for the buck with serm.

In any case, injections of anything for a long time do increase my concerns about sterility, endotoxins, unknown excipients, etc. My GLPs are tested for most of that now with the group buying/testing, but that is not the case with my non-GLP peptides.

Incidentally, women, especially younger women, don't respond as much to GH peptides:

Older MenVery HighLow baseline + high liver sensitivity.
Older WomenModerate/HighLower estrogen levels allow better IGF-1 conversion.
Younger MenModerateHigh baseline, but very high liver sensitivity to GH.
Younger WomenLowHigh baseline + estrogen-induced GH resistance.

All of the human clinical trials of tesamorelin were done in people with HIV lipodystrophy, and if I am remembering correctly all at 2mg/day. To the best of my knowledge, no studies have ever been done in humans in any other state, so none in any kind of general population. None for obesity either.

So it can be said that it has been shown to reduce visceral fat in persons with HIV lipodystropy, and there did not seem to be any concerning effects on cardiovascular risk markers in that group, apart from blood sugar. This does not mean it is tested or known to be safe in the general population, but has much better evidence than anything else that messes with the GH system. And it can obviously cause GH related side effects like increased sugars and insulin resistance, fluid retention and carpal tunnel syndrome. And may or may not increase cancer risks, and reduce lifespan.

Any claims beyond this by pretty much anyone are bro science, not science. There is no scientific basis for days on /off treatment, but there is no scientific base for its use outside of HIV lipodystropy. As far as I am concerned anyone using the term protocol is making stuff up, I have yet to ever see one that is actually consistent with human trial evidence.

Given there is some evidence at least of being tested in humans, and most people taking it are going to be on GLP's reducing the negative effects on blood sugars, it is probably the safest option, ( if you have to use something that messes with HGH ) but getting sugars, lipids, blood pressure and IGF-1 tested is still a good idea. Just because the studies only used 2mg , does not mean 1mg is a problem. But it is quite a lot more expensive than HGH.
I'm debating a protocol, what it one cycles between hgh, tesa and ipa? Like 2 out of hgh in the morning and 1mg and 200mcg of ipa in the night. Will it be confusing the system too much or that way the body can be at its natural state.
 
I had bloodwork before I started any peptides and now at 8 weeks in. I am taking :
Reta 1.5mg - week
Tesa 1mg / IPA .3mg - Day
MOTS-C 1.5mg - Day
KLOW - 2.67mg Total - Day
NAD+ - 25mg -Day

My Bloodwork:
IGF-1 Before 138, Now 215
Insulin Before 3.6, Now 8.9
I know they are still within normal range. But what do these numbers really tell me?
 
Was your Tesa tested? I’m no expert but I don’t think I’ve ever seen someone run 2mg of Tesa and IPA daily to have their IGF-1 drop 6 points.
Yes it was tested for Mass and purity. 11.9 mass and>99 purity. I reconstituted with 2 ml BAC for the 2mg dose at 34 units. BTW, I’m 75 and GH are not as active as a 30 year old.

138 is pretty good for a 75yo! About where I am at 30 years younger. What were the z-scores? I'm guessing 215 is >2?
 
My IGF-1 lab result was it went from 102 (pre Tesa/ipa)to 96 after 5 weeks of daily doses of 2mg TESA/510mcg IPA. I guess that’s good.

My IGF1 went from 140 to 100 in about a month, after losing weight and sleeping not so well. So there might be other factors too.

If everything else is the same, I'd be disappointed.

Have you considered HGH?

Interesting your insulin increased that much while on reta? I would think any increase due to tesamorelin would be counteracted by reta, so I asked chtgpt and it said early on reta could increase insulin levels , but after weight loss and long term use it will reduce insulin resistance and insulin levels would reduce to below starting levels. So not surprising given you have been on it a short time.

As I have no idea of the normal range for igf-1 in a 70 yo, I asked chatgpt that as well , so 215 is around or just over the normal range for age depending on the exact test used, I would guess people taking gh or secretagogues are usually aiming for towards the top of the normal range for igf-1 , which is where you are.

I am 54, not 70
 
Sorry saw someone else made that mistake too. Top of the normal range is 250 at 40 yo and 200 at 70 so still in the ballpark of high normal for igf-1.

Ya on my labcorps test it said top was 255.
I know I am within range, but didn’t know if being high in the range was better than being lower in the range.

High in the range, ā€œbetter,ā€ depends on how you define that word…. I always like to be high in the range of many things.

I guess it is better because it means the Tesamorelin is working.
