I posted this at another forum and since I plan to be more active here due to having a bit extra time to spend on the forums, I though I would add a thread here and hope that it helps other out a bit. I'm no know it all, but I would like to think from my years of research that I got a decent handle on things, anyway to the info ---v



Peptides, Tissue Growth & Protection and Practical use surrounding them

Hello all of you in internet land!
Today I wish to cover the subject of peptides and their possible uses.
There seems to be a lot of people out there unsure of what peptides are or flat out think they are some sort of gimmick.
I was at one point in time in the same boat, so no worries keep reading and you might learn something. After many years of research on this topic and countless personal experiences with peptides I feel I am qualified to try to help others out there by putting together this article covering the most popular peptides, their uses, how to use them safely and most effectively.

What so WHAT in the world is a PEPTIDE???

Isn’t that the stuff in my wife’s shampoo???

Well…… I might be. But not all peptides are the same! Just like not all amino acids are the same.
Peptides are actually very similar to amino acids (protein molecules) believe it or not.
A peptide is a short, large molecule of an amino acid molecule that can bind chemically to other molecules to form a larger molecule by peptide bonds. They are listed as a peptide or protein depending on their size.

I know it sounds confusing and in some ways it is. But it is not too hard to understand them.
There are many kinds of peptides out there some are your basic protein type peptide that I will not bother to cover at this time or that would make this more of a diet article than a peptide article. Another is a “peptide hormone” they are secreted into the blood stream and have an endocrine function in the body.[1]

There is even something called a neuropeptide. One of many for e.g. is DSIP (Delta Sleep-inducing Peptide). They are small protein-like molecules used by the neurons to communicate.
They are much smaller than a neurotransmitter and are considered neuronal signaling molecules and they affect many functions in the brain like; pain, hunger, memory and can even effect you’re learning abilities!
Still think Peptides might be a gimmick? HA I sure don’t. I think they are GREAT!
No I won’t be talking about neuropeptides today, but I wanted to at least mention them because I feel they are pretty cool and very important.


Today I will be talking about Peptide Hormones!

Peptide hormones are not the same as steroid hormones.
Steroid hormones are synthesized from cholesterol, and are lipids (they are fat based). While peptide hormones are proteins and are formed by a sequence of amino acids.
As mentioned above these are the ones that have physical effects on the body like growth and repair and has been of very big interest to the bodybuilding scene and in recent years I feel at a massive scale due to the internet and many places selling these peptides.
I felt I really should put something together about these powerful peptides and how they might help you in your quest to recovery, fat loss and growth.



I will start with the basics of what each one does then I will get into more detail on how you can use them safely and effectively.

GHRP-2
Is a human growth hormone secretagogue. That means it stimulates the body's own release of HGH. It is a ghrelin receptor agonist is also seems to have some protective effect on some tissues and an anti-inflammatory effect as well. The excessive hunger some feel with GHRP-6 use does not seem to be an issue with GHRP-2. The half-life is about 20 minutes so multiple doses per day are optimal.

GHRP-6
Is also a human growth hormone secretagogue and stimulates the body's own release of HGH. It is a ghrelin receptor agonist and also seems to have some protective effect on some tissues and an anti-inflammatory effect as well. The half-life is about 20 minutes so multiple doses per day are optimal.
*Note: GHRP-6 seems to cause excessive hunger in some people compared to GHRP-2. It is not a bad thing per say but depending on if your bulking or cutting you may prefer one over the other.

CJC-1295
Is a growth hormone releasing hormone (GHRH) and it aides in the stimulation of the pituitary gland to increase production of growth hormone and stimulates GH and IGF-1 secretion. It will keep a steady increase of HGH without an increase in prolactin as can be an issue for some peptides of this nature. It is an analog to a peptide that is naturally produced to stimulate pituitary production of growth hormone. It has a half-life of about 7-10 days. This means once a week dosing is optimal in most cases.

CJC-1293 (CJC w/o Dac)
Is also a growth hormone releasing hormone (GHRH) and it aides in the stimulation of the pituitary gland to increase production of growth hormone and stimulates GH secretion. It is an analog to a peptide that is naturally produced to stimulate pituitary production of growth hormone. The GH pulse from a single administration of CJC-1293 seems to be greater than that of CJC-1295 but duration is shorter. There is debate on which is better but both are useful regardless.

IGF1 Des
IGF-1 Des is an IGF-1 analogue of our native igf1 with the last 3 amino acids in the IGF-1 chain removed. That leads it to have little protein binding (good thing), but similar action causing it to be about 10 times more potent than normal IGF-1.[2] The active life is still fairly short, only about 20 minutes making multiple doses daily optimal for some users while others still feel once a day dosing is still worthwhile and the way to go.

IGF1LR3
Is also an IGF1 analogue with a 13 amino acid extension at the N-terminus. The alteration leads to less binding in the body greatly extends its half-life from 20min to about 20+ hours. Once a day dosing is optimal.

IGF1Ec / Mechano Growth Factor (MGF)
IGF1 Ec is derived from IGF-I but its effects differ from the systemic IGF-I produced by the liver. It is released as a pulse following muscle damage, is involved in the activation of muscle stem cells and also seems to protect the myocardium against ischaemia, which improved cardiac function after heart attacks. There is debate on dosing but i feel post workout (once daily even on non workout days) is a good way to go about it.[3]

MT2
Melanotan II (MT2) is a melanocortin. Melanocortins (MCs) are a family of multifunctional peptidergic hormones. MT2 is an analog of these and plays a role in the tanning process but will vary between skin types with its use. It is not really used in any growth as HGH or igf1 would be, but I feel due to its potential skin protection that I should add it in this article even if tanning is not the main focus of this article.



As you can see all this stuff seems to revolve around IGF1 and HGH, so to understands its effects does not mean needing to fully understand each and every peptide (though a basic knowledge should be known about each one you use). Each peptide is working as either an IGF1 analog or as a HGH releaser and HGH converts to IGH1 giving most of its tissue growing effects anyway.

It’s more understanding what IGF and HGH do in the body, to fully understand what these peptides can potentially do for you.

I would like to talk mainly about IGF1 as I feel it is the main cause for growth over that of HGH solely.[4]
The liver is the organ mostly responsible for the production of serum IGF-I even when taking exogenous HGH it is still mainly converted in the liver.

IGF-1 acts differently in different types of tissues its not all tissues grow from its effects. When active in muscle cells and associated cell’s they stimulate growth by increasing protein synthesis along with amino acid absorption. IGF-1 also plays a role as a source of energy; IGF mobilizes fat for use as energy in adipose tissue by preventing insulin from transporting glucose across cell membranes. This results in the cells having to switch to burning off fat as a source of energy which I feel is a great quality about IGF-1.IGF also seems to mimic's insulin in the human body. It makes muscles more sensitive to insulin's effects.[5][6]

I think one of the most interesting effect’s IGF has on the body is its ability to cause hyperplasia, that is when an actual splitting of cells occurs leading to more cells. You are basically your growing more cells with the use of HGH and IGF-1.
Hypertrophy is what occurs when practising weight training and steroid use. Hypertrophy is simply an increase in the size of muscle cells but not growing new cells. In humans after you are done puberty you mostly have a set number of muscle cells that you have developed with that doesn’t vary much.All you would be able to do is increase the size of these muscle cells, but you don't actually gain more of them.
This is not good for someone with “bad genetics” in the area of muscle cells.
With IGF use you are able to cause hyperplasia which increases the number of muscle cells and gives you the ability to change your genetic capabilities in terms of muscle tissue and cell count.[6]
Being able to alter a person’s capacity to build muscle density and size is an awesome thing to have control over.
When you do a “cycle” of HGH releasing peptides or even straight use of IGF1 analogs on its own, you not only add to growth and recovery while on them, you give yourself a greater number of cells to work with and down the line grow then.

When you finish a cycle of IGF-1…. in a way you are not really finished because you are still left with these new cells regardless of stopping the use of IGF1 or HGH releaser peptides and that is one of the things I just LOVE about HGH and IGF1. The fact you have residual effects is awesome for muscle building!


OK, OK we know igf1 causes growth of size and cells, but how do I use this stuff effectively?
Well by knowing the basics of each peptide, how they might have a synergy when used together and fully understanding the effects of HGH and igf1 that’s how!

Unfortunately a lot of the use of IGF1 and HGH by bodybuilders and athletes is an underground trend of their use and you might not find some of the info needed to stack them optimally together or use them in a home setting.
I wish to give you some of that information here.

Secretagogues are different from GHRH's, they share no sequence relation and derive their function through action at a different receptor and it has been established that the use of Growth Hormone Releasing Hormone (CJC1295 is one for e.g.) and a Growth Hormone Releasing Peptide (GHRP-6 or GHRP-2 for e.g.) together results in synergistic release of GH from pituitary.
It is like saying 2+2=5 not 4, if you get what I am trying to say.

I strongly rec stacking a GHRP with a GHRH for optimal results in tissue growth and fat loss, even if also using an IGF1 analog in the same cycle as some like to do.


Here are some good examples of “peptide cycles” (Taken Sub Q):

1#
Wk1-8 40mcg ed IGF-1LR3

2#
Wk1-12 1000mcg (1mg) every week CJC-1295
Wk1-12 100mcg 2-3X ed GHRP-2 or GHRP-6
Wk1-12 10-20mcg ed IGF1 Ec (post workout’s)

3#
Wk1-12 100mcg 2-3X ed CJC-1293 (CJC w/o Dac)
Wk1-12 100mcg 2-3X ed GHRP-2 or GHRP-6

4#
Wk1-8 40mcg ed IGF-1LR3
Wk1-12 100mcg 2-3X ed CJC-1293 (CJC w/o Dac)
Wk1-12 100mcg 2-3X ed GHRP-2 or GHRP-6

5#
Wk1-8 10-20mcg 1-2X ed IGF-1 Des

6#
Wk1-8 10-20mcg 1-2X ed IGF-1 Des
Wk1-12 100mcg 2-3X ed CJC-1293 (CJC w/o Dac)
Wk1-12 100mcg 2-3X ed GHRP-2 or GHRP-6

7#
Wk1-8 10-20mcg 1-2X ed IGF-1 Des
Wk1-12 1000mcg (1mg) every week CJC-1295 (Sub Q)
Wk1-12 100mcg 2-3X ed GHRP-2 or GHRP-6

8# (MT2 cycle is for tanning purposes only, dependent on skin type and these are guidelines only)
Wk1-4 0.5mg 2-3X a week of MT2 (10min tan every week)
Wk4-8 0.5mg 1X a week of MT2 (10min tan every other week)
Wk8-? 0.5mg 1X a month of MT2 (tan and dose as needed) *maintenance

These cycles above would be optimal ways of using these peptides for muscle growth and fat loss.

Using one or more of the HGH releasing peptides along with an IGF peptide like IGF-1lr3 could lead to growth and more fat loss over just the use of IGF-1lr3.
But the use of one or more of the HGH releasing peptides without IGF-1 could lead to less total gains in mass as well. So stacking is goal dependent.
I feel they stack together very nicely personally and I highly recommend IGF1LR3 to my friends new to and interested in peptides.

IGF1lr3 or IGF1 Des are good peptides to start out with due to the simple ease of their.
Then once you feel comfortable I would highly recommend stacking it with one of the GHRP’s and GHRH’s for maximum results.

There are new discoveries every day in the field of “the human body” and I would be VERY Happy If I had some effect on this knowledge spreading, so I hope you learned something and enjoyed my article on these peptides and how to use them most effectively and safely.

I look forward to helping all I can and making more of these kinds of informative articles.
Till the next time,







Take care!

Good read!

i'm seriously considering a cjc1295/ghrp6 cycle.

all your info agreeswith the research i've done.

one question, i've heard that to optimize results it's best to take these peptides on an empty stomach and not to ingest any carbs for 45 min after your shot.

I found some pretty comprehensive info on another board, the article gave scientific references, it sounded like the guy knew his stuff.

The theory is that the presence of insulin will blunt GH secretion.

yes basically this is the theory I go by, i just pin peps 1hr away from eating and try not to over think that part too much.

The reason for this is that hyperglycemia and ingestion of food stimulates the hypothalamus and digestive organs to release somatostatin which in turn inhibits pituitary release of growth hormone. somatostatin is released from cells in the stomach, pancreas and intestines during the digestive process (it is also released from other locations). somatostatin inhibits GH release and opposes the affects of growth hormone releasing peptides thus an injection of peptides to stimulate natural GH release needs to be done on an empty stomach and you need to give your body time to release the GH before eating.

Unfortunately, the debate on igf in adult skeletal muscle tissue is ongoing. Cell hyperplasia (additional myotube formation) has not been demonstrated with exogenous administration of IGF or its other derivatives. What appears to be the case is that igf plays a role in increasing size by increasing the number of cells incorporated into the individual myotubes but it has not been shown that igf can impact the number of myotubes formed.

I feel it plays a big enough role that it has some effect on new cells with the doses we use for growth. might not be hard proof YET, but I believe it is the case. I mean there is more to new cells then just IGF, igf is just a stone in the road of a few factors.
I love IGF1 I know that much! haha
Thanks for the post and ref! :-)

Nice write up. Im running cjc1293 and ghrp 6 right now. Have been for 4 months. So far it has been worth me continuing.

yeah after about 2mo you really start to see nice effects, like it was real hGH being used. great stuff!
I just dont like pinning 3-4 times a day haha. so i wont use it for 1-2 years straight, but 4-6mo runs is very nice.
man im temped now...
ill probably just use some IGF1 Des i got in fall. got a nice var/test recomp cycle starting up now :-)
