what's your gh dosaging?

[benfrankparkway]

I’m interested in your comment about correct dilution ratios as I’ve been running various peps for quite awhile including a 2.5mg maintenance dose of Tirz and not sure I’ve ever seen any data on what constitutes correct dilution ratio. I’ve searched around a bit but nothing definitive. If you have a link or something would appreciate it as the immunogenicity thing is something i wish i knew more about when I started using peps. Thanks in advance

Thread 'The FDA makes the case for filtering peptides'

Nov 16, 2024

I just finished listening to the October 29th meeting of the FDA Pharmacy Compounder Advisory Committee meeting.

The FDA is increasingly focusing on the threat of immunogenicity from peptide use, and beginning to quantify the differences between pharma and compounder formulations, which highlights just how much worse our UGL peptides are likely to be in this regard than the original pharma products they're copying.

TLDR: Filtering your peptide will at worst, do nothing, and at best will reduce your exposure to some unknown, potentially serious adverse health effect that may not...

Bump to this as well as it makes me wonder was I using proper dilution for peptides, GH. Also he mentioned filtering, which I never used before.

For a peptide available as pharma, the easiest way to establish proper dilution ratio is to see what's used in the pharma product.

For instance:

All doses Tirz, up to 15mg are .5ml.

So for a 30mg vial, you'd want dilution no less than 1ml. More dilution is ok, preferable in fact, less is not.

That's for limiting aggregation that's promoted by higher concentration.

However, despite .5ml being ok for a 15mg dose, in terms of not generating excess aggregate formation, the other reason for a volume of .5ml even for the lowest 2.5mg dose, is pharmacokinetics. Higher volume subcutaneous injections are absorbed more slowly than smaller volumes. By limiting the rate of absorption this way, blood concentration rises more
slowly, reducing the risk of side effects and their intensity.

We can see this control over uptake rate more clearly in Sema, in which Novo Nordisk uses a .5ml volume for all doses up to 1mg, switching to .75ml for 1.7mg and 2.4mg doses. Both those volumes are far beyond what's needed to reconstitute the peptide itself, but .75ml is used to further slow the absorption of the larger doses.

The other reason for reconstitution rate is again, controlling immunogenicity. Higher concentrations of peptides are more easily processed by immune response mechanisms than lower concentrations. Essentially, a greater concentration of an "invader" elicits a more intense immune response, which we want to avoid. You may notice that vaccines, essentially proteins in which we want to maximize the immune response, are given in very concentrated, often site reaction (pain inducing) doses.

For GH, there are many products on the market. Rate of uptake doesn't seem to be a concern. The most concentrate I've seen is .05ml per iu. So no less than 1.8ml per 36iu volume.

However, for UGL it's important to remember that they don't contain the anti-aggregation excipient ingredients used in pharma formulations.

For peptides generally, greater dilution is not a problem, so it's best to err on the side of diluting to the point your dose is somewhere between .3ml and .8ml , which is considered the "ideal" subq volume (for ease of measurement and comfort) when other considerations don't override that range.

If it's a "research" peptide. It's best to reference several studies to see what the researchers are using in human trials, and use that as the guide for dilution.

Finally, I'll point out that since most people understand the closer to "pharma" one can get, the better, use pharma grade BAC like Hospira. It's relatively cheap, especially in case quantities, and since it represents 99% of what's being injected, goes a long way towards approaching "pharma" quality in your reconstituted peptide,

I'll address the other questions a bit later.

Thanks for the info, I’m going to have to rethink my dosing a bit

Unfortunately the public data for that study doesn't go into adverse events and immunogenicity.

The thing to bear in mind is immunogenicity isn't binary. It's not on or off. It's a sliding scale. A little is often no problem, as long as it doesn't rise over time. At lower levels, site reactions like pain and redness are common. At higher levels the drug starts to lose effectiveness as you become "immune" to it. Worst case, you develop immunity to the natural hormones the peptides are mimicking.

When we see pharma trials. they're using a finished product that's been engineered and tweaked to minimize immunogenicity. Everything from manufacturing the peptide, the excipient ingredients used in the formulation, to the packaging it's contained in.

For instance, pharma uses the recombinant method, producing Sema and Tirz with yeast that's had its DNA reprogrammed, vs the synthesized type UGL uses. Recombinant peptides appear more "natural" to the immune system vs the "alien" synthesized alternatives which trigger stronger immune reactions.

The specific formulation, tightly controlling things like PH also contribute greatly to keeping immune reactions down. Something no one pays attention to with UGL peptides.

If you took a pharma peptide, and intentionally did everything you could to make it as immunogenic as possible, you'd end up with something similar to what UGL peptides are today.

So with this in mind, as an end user, doing everything you can with the factors in your control to minimize immunogenicity is a wise course, Weekly dosing induces a lower immunogenicity reaction than daily, Reconstituting properly. Filtering.

Pharma Sema is recombinant, but both pharma Tirz and Reta are made via peptide synthesis.

Here are my thoughts on the matter. Like many others here, I’ve experimented with various strategies and protocols. Ultimately, I discovered that taking a “bolus” dose before bed works best for me. The benefits I’ve experienced include improved sleep, enhanced recovery, and a fuller appearance throughout the day— in a positive way. Conversely, when I attempted to split my dose throughout the day, I encountered more undesirable side effects such as water retention, headaches, and elevated blood pressure. It seems clear to me that there isn't a one-size-fits-all approach to this compound.

It seems clear to me that there isn't a one-size-fits-all approach to this compound.

This is the truth, it’s an incredibly personal drug that varies on impact and feels so greatly person to person that no one size fits all works. Split dose feels way better to me personally, but requires being meticulous with meal planning.

I completely agree with you mate! Despite my efforts to strategically time my meals around my multiple doses throughout the day, I still experienced the negative side effects I mentioned earlier.

I have some HGH Frag on hand that I've been researching, and it seems to align with what you mentioned regarding dosing and meal timing. I’d love to hear if you have any experience with it and whether you noticed any significant benefits. I'm considering taking a bolus dose of HGH at night and then another bolus dose of Frag in the morning before my fasted workout.

Additionally, I'm having trouble reconstituting the Frag. I've tried various types of water to mix it, but I can't seem to get it to dissolve properly. Has anyone else encountered this issue, and do you have any solutions?

the only time i have had trouble with reconstitution of hgh/peptides is when i try to use "to little water" , it may or may not be your problem, just speaking from personal experiences, i use .10 bac water per iu of hgh/peptides, so my 17 iu vial of hgh i will use 1.7 ml of bac water,,,,,

Yeah I’ve tried different water amounts it just won’t fully dissolve. I’m sure I’ve seen somewhere it’s an issue with Frag.

Always used 1.8 ml of Pfizer Bac water per 36/40iu vial of HGH, never had any issue, I just do it the night before I dump it all into several ready to use syringes that I place in the fridge for the week.

2 mL BAC should dissolve the cloudiness. Sometimes it takes a day.

You might also look into adjusting the pH, but more BAC usually does the trick.

sub q, directly into my scrotum, while singing "Fortunate Son" by Creedence.

Hope that's interesting enough

i guess the interesting part of the protocol to me is that you have fat on your scrotum!! Cool enough... no need for proof.. i believe you!
