so we're always looking for the best
tools to improve our bone health this
video is going to present an option that
I bet you've never heard of and I'm
going to tell you exactly what it is
where we get it and how we use it but
first let me give you a little
background this compound has evidence to
support its benefit for muscle Health
metabolic Health heart health improved
sleep improved performance as well as
bone health now if that sounds too good
to be true trust me that it's not but
the research does leave room for
improvement now I'm curious about what
you found to be the Magic Bullet in your
bone health program and if you have
something that you'd like to let us know
about just leave a comment on YouTube
I'd love to hear about it so what is
this thing that I'm talking about well
it's a peptide called hexarelin now a
lot of people don't know about peptides
so let me just give you a little
background here so peptides are these
interesting molecules generally
naturally occurring that are just simply
chains of amino acids and amino acids
are the building blocks of protein so
these are simply just kind of like short
proteins but with amino acid chains less
than 50 amino acids in length most
proteins therefore would be over that
and again they are naturally occurring
molecules for the most part and they act
generally as signaling molecules within
the body so in some ways there's similar
to Pharmaceuticals and in fact some of
these peptides do end up becoming
Pharmaceuticals some famous ones you've
probably heard of would be like insulin
like the hormone insulin is actually a
peptide OIC which is a a gp1 Agonist
used now for weight loss mostly but
originally studied for diabetes and that
is also a hormone and a peptide so
there's a lot of peptides that are
actually already on the market but what
we're talking about are the things that
maybe they were tested for
pharmaceuticals and dropped for various
reasons or they've never been
pursued because they're naturally
occurring products and unless a
pharmaceutical company can alter them
either through delivery or in some
unique Way by adding another component
of a compound then they can't actually
be p ented so if you can't patent a
product then if you are a for-profit
company and you need to invest Millions
potentially billions of dollars in
something you're not going to want to do
that with something that you can't
patent that's naturally occurring
because you're not going to get your
money back so unfortunately a lot of
these products do then end up not going
to Market and not being available
commercially because they simply can't
be patented now that said many of these
peptides do have adequate research to
stratify risk and potentially the
benefit so hexarelin is one of these
peptides where like I said the research
isn't perfect but I think there's
adequate research to use it for patients
and there's adequate research to present
it as an option because there is
research that is both animal and human
and intervention style and trial and
there are recommendations to use this as
a commercial drug it's just not
available as a commercial drug all right
so what is this thing called hexarelin
so hexarelin is a synthetically derived
growth hormone releasing peptide or a
gin analog and I'm going to give you all
the science here it stimulates the
growth horm hormone receptor by
activating the growth hormon
secretagogue receptor in the brain so
did I just lose you so don't worry
here's the non-medical version of that
statement hexarelin is a short chain of
amino acids that act as a signaling
molecule in the brain to release growth
hormone does that make more sense so
growth hormone we know is important
because as we age growth hormone
declines in fact it starts declining
really early and while some anti-aging
gurus are Advocates of injecting growth
hormone there are some potential
negative effects of injecting growth
hormone and it's very difficult and
expensive to find so peptides that work
around the growth hormone axis have been
studied and may provide some of the
benefits of growth hormone and avoid
some of the potential negatives of
growth hormone are more easily available
less expensive and hexarelin is in this
group all right so again remember I'm
going to show you exactly where we
consider this peptide but first let me
walk through a few studies that
encouraged me to offer this to our
patients all right so study one study
one is a mouse model and we're going to
go through several animal models so
study one is a mouse model and we're
going to go through a lot of animal
models here not a lot but a few
hexarelin when given to a mouse it
increases pulsatile growth hormone
secretion now pulsatile is important
because hormones in general we don't
want to be present all the time so we
want it there and then we want it gone
it's also important because when you
pulse hormones then a lot of times you
won't disrupt the natural regulation of
that hormone and we saw that in mice in
this study Now growth hormone when you
give it as an injection is going to more
look like chronic elevation of growth
hormone and that's I think is where some
of the issues occur with growth hormone
but as far as the effect of the
hexarelin on the mice what we saw is
that they had increased fat burn or
lipolysis they had reduced fat
production in the liver so their denovo
fat production was reduced they had less
visceral fat likely as a result of that
they had lower triglycerides in their
blood and they had improved insulin
sensitivity but didn't alter the insulin
levels or glucose tolerance or anything
negative when it comes to the metabolic
function so all that's pretty cool but I
didn't say anything about bones in there
did I but don't worry we got more so
study two is a more recent Mouse model
and this one again was looking at
intravenous hexarelin and it again
showed benefits from an insulin
sensitivity perspective they showed
again that increased fat burn decreased
fat Mass but the most important finding
here and why I included this is that it
increased lean muscle mass so compelling
in an animal model that it increases
lean muscle mass all right so then third
study again on mice looked at
mitochondrial function and mitochondria
those little factories of energy within
the cell and the mitochondrial function
went up again with hexarelin and again
benefits in fatty acid production uh
sorry fatty acid metabolism that's
burning the fat and then also protective
of the beta cells in the pancreas that
make the insulin so again there's a
benefit of insulin here now this fourth
one is a a rat study and this one's
specifically looking at the formation of
plaques so the things that cause heart
disease disase the thing that caused
heart attacks and strokes and what they
found here is that the hexarelin
actually suppressed the formation of
plaque and all these different markers
that they looked at but essentially the
things that caused plaque were reduced
when the the rats had hexarelin compared
to Placebo so that's actually kind of
cool and then the last animal study I'll
show you I only included it just because
it makes sense from a dosing perspective
why the oral dose is so much higher than
the subcutaneous dose because they found
that the bioavailability once it goes
through the gut is about 10% of that if
you were to do it subcutaneously or
through injection so before I get to the
human studies let me just do a quick
mention of our master class so if you
are confused about all of the 160 things
that we're talking about in our videos
you want to hear me put it together in
one place go to our either our website
optimal human health.com or look for the
link in the description below on YouTube
and sign up for our free master class
again totally free you'll hear me put
all the stuff together and then answer
questions for 10 to 15 minutes it's been
really helpful for a whole lot of people
so I would encourage you to do that if
you haven't done it already Okay so a
couple of human studies here so the
first human study was looking at
hexarelin versus a couple other things
including growth hormone itself and what
they were looking at this for was
specifically in cardiovascular function
and what would be the potential benefit
of using this in someone who let's say
had a bypass surgery so a big heart
surgery and what they found is that
hexarelin was independently acting
differently than growth hormon so even
though it acts through the growth
hormone path way there must be receptors
for hexarelin and other tissues that are
more specific to this type of peptide
because there was impact improved
function from a cardiovascular
perspective with hexalin that was better
than the other two things that they were
studying including growth hormone so
that's kind of cool another study just
simply demonstrated that if you give
hexarelin the growth hormone does go up
but again it's pulsatile so it is up and
down it can augment normal growth
hormone secretion all right second to
last study is a study on both men and
women that shows that Meal Time
consumption doesn't affect the serum
levels of this now this might not seem
that important but a lot of these
peptides particularly in the growth
hormone and the igf category which I'll
explain in another video all of these
peptides are generally recommended to be
consumed fasting and that can be a
challenge for people because a lot of
times they want to consume them around
meals so what this next study showed is
that essentially that didn't matter and
that the meal time did not affect those
that's different than a lot of
especially the igf-1 peptides and then
the last one arguably most important one
is an older study but it looks at
hexarelin use on elderly human subjects
and what they did is they did a 15-day
trial of oral hexarelin at a pretty high
dose of 20 milligrams and what they
showed first and foremost is that there
were no negative side effects there was
no desensitization meaning there was no
alteration of the growth hormone pathway
and that the the their conclusion was
that the pulsatile treatment of
hexarelin through growth hormone
actually restored growth hormone levels
in elderly subjects so again you're kind
of Mimi thinking what it would be like
to use growth hormone but not quite all
right so I haven't mentioned bone health
yet so let me just talk about this last
study so this last study is a rat study
so it's again it's an animal model not a
human study but what they did is they
looked at the impact of hexarelin on the
loss of bone in an animal model that
would typically lose bone and so
essentially what they did is they in a
neutered rat model you would see loss of
bone and you could monitor the increase
in in bone turnover markers Etc what
they noticed is that if you use
hexarelin it blunted all of those bone
turnover markers so the rats were not
losing bone as they were given this
peptide whereas if they were given
growth hormone historically even growth
hormone would not have prevented the
loss of of bone so again hexarelin has
an impact on bone that growth hormone
does not so is that an animal model yes
is that a human model no you know do we
have good clinical trials on this no and
so this is kind of the rub with a lot of
the peptides this one in particular I
would say the evidence is present but
not amazing but is it enough to support
patient use well I look at it like this
we're never going to see large clinical
trials on humans with the outcomes that
we're looking for because pharmaceutical
companies are just not interested in
that benefit so what do we have to do
well we use the evidence that we have
decide whether or not we think it's safe
and then we can plug it into a risk
benefit ratio right so what is the risk
of this thing that we're considering and
so a risk for something like this that
has been studied and there are other
trials that I didn't mention too there's
dog studies and there's more studies so
this isn't all of the evidence but we
look at the potential risk of which
there really doesn't seem to be at the
doses that are being used here and then
we talk about the benefit so the benefit
here being that we are utilizing a
growth hormone pathway without the risk
of growth hormone we are getting some of
those benefits including increas Le
muscle mass including likely decreased
in visceral fat improved metabolic
function potentially improved
cardiovascular function improved an
arterial function all of those things
are pretty darn compelling so then when
we use this for the whole big picture
could it help bone health well it seems
like it likely would because we've been
using peptides for this space around
bone health and muscle mass for a long
time and this is just another one that
fits into those categories Additionally
the risk around naturally occurring
products are generally going to be
smaller assuming that the dose is
reasonable we never want to assume that
something's not going to be harmful but
again if we have trials where nothing's
come up then we feel pretty confident
moving forward with something like this
even though it is certainly in a gray
area so we clinically have access to
both the oral form so a capsule form as
well as subq hexarelin most people of
course prefer the oral form and that's
fine we like to use it for people that
are really struggling with muscle mass
and we see this very very frequently
with osteoporosis because those two
really do go hand inand so if someone's
struggling with muscle mass if they have
you know challenges with their bone
health and they're struggling to to
Really encourage that P1 and P side the
building side then this is a reasonable
tool to help encourage a pulsatile
secretion of growth hormone and augment
the normal growth hormone pattern in
that specific population and I told you
that we were going to talk about dosing
so when it comes to dosing you can look
in again the human studies you can look
at some of the animal studies and subq
is a common way to do it that means a
subcutaneous injection versus
intravenous now obviously we're not
giving people intravenous medications
through our our platform but we have
access to subq and oral the subq dosing
recommended by thees is around 0.1 to
0.3 mg so therefore based on the study
demonstrating oral bioavailability being
about 10% of that then we would
recommend oral dosing around 1 to 3
milligrams and so that's what we've been
doing and again this is something that
we do see a benefit for some patients
okay so for those adventurous folks who
want to go down the peptide pathway the
next question is where do I get it and
this is something that I wanted to talk
about specifically about this peptide
but really all peptides in general so I
not to discuss options that are not
easily available for most people but I
get so many questions around peptides
that I did want to at least bring up a
couple of options and see what their
respones like the challenge with
peptides is that you really do need to
work with a provider who understands
peptides who's been trained in peptides
I went through a whole certification
course through a4m I'm a member of the
international peptide Society so I've
looked at a lot of this data and I
understand how to prescribe these things
so I'm not the only one that can do this
there's lots of people that can do this
maybe not lots but there are lots of
people that have been trained but what I
want to encourage you to do is to look
for someone who has that training be
very weary of direct to Consumer
pharmacies so these things do exist
there are people out there that are
selling these to people that should be
coming from a pharmacy that would
require a physician's prescription I
want to encourage you not to use these
not because what the companies are
making is not safe I can't say whether
they are or whether they are not but the
challenge that I've seen is around the
dosing so it's very challenging for
someone who doesn't have the training to
understand what it means to put a
certain number of MLS of hydrostatic
water into a powder and make a liquid
and then inject that and in fact we've
seen that we've seen a ton of reports of
this around the gp1s I mentioned OIC in
the beginning of this video and that's a
a product that a lot of people are
trying to use for weight loss it's
expensive and it's hard to get insurance
to pay for it so some people are using
these directed consumer Pathways and
they're screwing up the dosing because
again it's not simple in fact it's
really challenging for us to even create
the protocols for our team to be able to
prescribe them accurately we have to go
through so many checks and balances to
make sure that we're not you know
missing a decimal point here or whatever
so it's challenging to do this on your
own and the directed consumer products
do not walk you through this and they
offer no support because it literally
says on the product not for human use so
unfortunately people still like to go
down that pathway um and we're seeing
unfortunately a lot of people get
injured as a result of that now that
being said does that mean that we
shouldn't use peptides at all no
remember that peptides are if you're
using the ones that have been
demonstrated safe through research
peptides should be safe particularly the
doses that are being recommended by
providers that are trained in these
things that is not to say that things
are are without Risk Everything has risk
in fact just a quick reminder that even
oral let's say anti-inflammatories like
nonsteroidal anti-inflammatories like
ibuprofen because those are direct to
Consumer there have been issues with
dosing different tolerance levels and
there are about 20,000 deaths per year
from ibuprofen or other
anti-inflammatories in the United States
and this is every year over and over and
over again so you just need to be really
cautious about what what you're putting
into your body know what it is why
you're using it what the right dosing is
and if you have any contraindications
for something please understand that as
well really just work with the provider
who can help guide you down these things
that's why the doing yourself model can
be such a huge Challenge and remember
this that osteoporosis isn't the end but
deciding to reverse it is a beginning
