Ipamorelin

Ipamorelin is a growth hormone releasing peptide. It stimulates the body to release more human growth hormone and igf-1. Increases in gh and igf-1 can result in many benefits including:

- Builds Lean Tissue
- Lowers Body Fat
- Improved Recovery from training
- anti aging
- Improves Mood and Sleep Patterns

Ipamorelin is similar to other GHRP’s such as GHRP-2 and GHRP-6. However Ipamorelin does not cause sudden spikes in prolactin or cortisol like GHRP-2 and GHRP-6 can do. Both of those hormones when elevated can cause negative side effects. Cortisol is a steroid hormone that is released when stressed and can be very catabolic. Prolactin counteracts the effect of dopamine, which is responsible for sexual arousal. Elevated prolactin can cause a variety of unwanted physical and psychological effects.

Raun K et al. (1998) highlighted ipamorelin’s beneficial effects over the other ghrp’s. In pentobarbital anaesthetised rats, ipamorelin released GH with a potency and efficacy comparable to GHRP-6. In conscious swine, gh release after ipamorelin injection was high and again vey similar to GHRP6. In the same study GHRP-2 displayed higher potency but lower efficacy. The specificity for GH release was studied in swine. They found none of the GH secretagogues tested affected FSH, LH, PRL or TSH plasma levels. Administration of both GHRP-6 and GHRP-2 resulted in increased plasma levels of ACTH and cortisol. Very surprisingly, ipamorelin did not release ACTH or cortisol in levels significantly different from those observed following GHRH stimulation. This lack of effect on ACTH and cortisol plasma levels was evident even when extremely high doses of were used. Ipamorelin was the first GHRP-receptor agonist with a selectivity for GH release similar to that displayed by GHRH.

A pharmacological profiling using GHRP and growth hormone-releasing hormone (GHRH) antagonists clearly demonstrated that ipamorelin, like GHRP-6, stimulates GH release via a GHRP-like receptor. However ipameolin is slow in its delivery unlike GHRP’s which spike GH levels at a faster rate. This another notable difference when researching ghrp’s. Moreover it has been shown that Ipamorelin is able to exert a dynamic control effect on the somatotroph population and on GH hormone content (Jiménez-Reina L et al. 2002).

A variety of promising effects have been displayed when ipamorelin has been studied. Adeghate E et al. (2004) examined the effect ipamorelin had on insulin secretion from pancreatic tissue fragments of normal and diabetic rats. Ipamorelin evoked significant (p<0.04) increases in insulin secretion from the pancreas of normal and diabetic rats. It was shown that ipamorelin stimulates insulin release through the calcium channel and the adrenergic receptor pathways.

Nitrogen balance is very important in humans. A positive value is often found during periods of growth, tissue repair or pregnancy. This means that the intake of nitrogen into the body is greater than the loss of nitrogen from the body, so there is an increase in the total body pool of protein. A negative value can be associated with burns, fevers, wasting diseases and other serious injuries and during periods of fasting. This means that the amount of nitrogen excreted from the body is greater than the amount of nitrogen ingested. Aagaard NK et al. (2009) studied the metabolic effects of Ipamorelin on selected hepatic measures of alpha-amino-nitrogen conversion during steroid-induced catabolism. Prednisolone was the steroid used to induce this catabolism. In prednisolone treated rats ipamorelin reduced CUNS by 20% (p<0.05), decreased the expression of urea cycle enzymes, neutralised N-balance, and normalized or improved organ N-contents. Therefore accelerated nitrogen wasting in the liver and other organs caused by prednisolone treatment was counteracted by treatment with Ipamorelin.

Ipamorelin is ideal for pre bed dosing

due to it’s long active life and minimal effect on hunger levels. When other GHRP’s are used such as GHRP 2/6 they can cause a sudden increase in appetite which can be awkward pre bed. Doses as little as 200mcg are highly effective but I feel Ipamorelin truly shines when you boom dose it. I have gone up to as much as 1mg pre bed and that was incredible. Although for most a dose of 500mcg would be more than enough when combined with a GHRH. My favourite peptide cycle to date has been CJC-1295 DAC with GHRP-2 through the day. Then a high dose of Ipam used pre bed.

Finally just want to list what I feel is a key advantage ipamorelin has over GH injections in a research environment. Unlike GH injections it does not shut down the body’s natural production of this hormone, it just enhances it. In the long run this is a huge factor and I feel future studies will highlight the importance of this in relation to health.

Anti-aging Growth Hormone Peptide

Human Growth Hormone (HGH) Dosage:

Month 1: HGH 2 IU one injection every other day
Months 2-4: HGH 3 IU one injection five days a week
Months 5-6: HGH 4 IU one injection five days a week
4-6 month cycles are optimal, year round if you are over age 35.
muscle building growth hormone

Human Growth Hormone (rHGH, HGH, or GH) is a protein molecule consisting of 191 amino acids. Genetically engineered human growth hormone is completely identical to the growth hormone made by the pituitary gland. Researchers have proven growth hormone therapy can reverse the biological effects of aging. HGH is widely appreciated for aesthetics and body recomposition, not necessarily as a performance enhancer.

HGH is released in pulses that take place during the day. Growth hormone is rapidly converted in the liver to its powerful growth promoting metabolite, Insulin like Growth Factor. IGF-1 is measured in the blood to determine the level of growth hormone secretion. Most of the beneficial effects of human growth hormone are directly attributable to IGF-1. Growth hormone replacement/stimulation is the most effective therapy to reverse the effects of aging.

At age 30 people have people have spent most of their lives with relatively high levels of HGH. HGH is responsible for growth during childhood as well as for repair and regeneration of tissue. By the time we are 30 our bodies no longer naturally produce enough GH to handle the damage that is taking place. As this continues, we age. Increasing HGH in our bodies, we can slow, or even reverse many of the manifestations of aging.




What HGH can do:
•Reduce excess body fat, especially abdominal fat. (The reduction of abdominal fat is the single most profound effect of HGH replacement in many people)
•Decrease in the waist to hip ratio. (Meaning fat is removed primarily from around the waist where it is associated with a high risk of coronary disease)
•Increase muscle mass and bone density. (and physical strength if combined with moderate exercise)
•Reduce wrinkling of the skin and some other effects of skin aging.
•Strengthen the immune system & enhance feeling of well being.

Human Growth Hormone takes several weeks to months of use benefit from its effects. There are a number of substances that increase the natural secretion of HGH. Some of them are amino acids. The relationship of certain amino acids to growth hormone is complex and varies greatly among different individuals and among individuals of different ages.

HGH is a Bodybuilding Research Peptide that comes in the form of lyophilized powder. Any other form that you see advertised or run across is likely NOT the real deal. The only way to administer true HGH is by sub-q or intramuscular injection. Be aware that HGH is not anabolic by itself. Careful measures need to be in place during reconstitution.

Reconstituting HGH, one vial contains powdered freeze-dried HGH and the other vial contains sterile water with a bacteriostatic preservative. When the user is ready to begin, a certain amount of the sterile water is drawn out of the second vial (with a needle and syringe) and injected into the first vial to dissolve the powdered HGH. The solution is then ready for injection. The unused portion is to be kept refrigerated. Use reconstituted HGH within 3 or 4 weeks.

The best way to begin HGH is to start with a low dose and ease your way into higher doses. This will allow you to avoid (or at least minimize) many of the more common sides of HGH such as lethargy, bloating and joint pain. Most can tolerate 1-2 IU per day with few sides. HGH administration should be done on an empty stomach as fats and carbohydrates blunt release. Natural production of GH is 1 IU, give or take a half.

Half life of HGH is 2 hours when injected sub-q with a four hour period which there is a suppression of naturally produced GH. Intramuscular injections shorten the half life. Subcutaneous injections over the long term can lead to spot reduction. Whether or not HGH has any localized benefit from IM injection is unknown, but speculated.

For bodybuilders growth hormone is best taken in conjunction with insulin, anabolics/androgens, and thyroid hormone. Insulin is extremely effective with HGH as the injections cause a down regulation of insulin sensitivity in the body. HGH is tightly regulated by the FDA, but HGH is not a controlled substance on the federal level in the United States.
