Product Description
Peptides are biologically occurring short chains of amino acid monomers linked by peptide (amide) bonds. 
The covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amine group of another. The shortest peptides are dipeptides, consisting of 2 amino acids joined by a single peptide bond, followed by tripeptides, tetrapeptides, etc. A polypeptide is a long, continuous, and unbranched peptide chain. Hence, peptides fall under the broad chemical classes of biological oligomers and polymers, alongside nucleic acids, oligosaccharides and polysaccharides, etc. 
Amino acids that have been incorporated into peptides are termed "residues" due to the release of either a hydrogen ion from the amine end or a hydroxyl ion from the carboxyl end, or both, as a water molecule is released during formation of each amide bond. All peptides except cyclic peptides have an N-terminal and C-terminal residue at the end of the peptide.

Product description:
Estradiol is a sex hormone that is present in both males and females, and is the most important form of estrogen in humans. In women, it plays a key role in the development and functioning of the reproductive system, as well as in the growth of certain bones. It also governs the distribution of body fat in women and is the main hormone responsible for the fact that women are shorter than men, on average. Both the ovaries and the adrenal glands produce it.
 
The menstrual cycle in women involves predictable variations in the levels of several hormones, with estradiol being one of them. It is involved in the ovulation process and prepares the inner lining of the uterus for implantation, should the egg be fertilized. Certain tests done on baboons and other primates have indicated that his hormone also plays a continual role in maintaining a pregnancy, helping it to last for the full gestation period.
 
As a sex hormone, it also triggers many of the developments of the reproductive system that begin in puberty. It is present throughout the reproductive years, and declines during and after menopause. This decline is precisely what causes many of the symptoms of menopause, such as hot flashes and night sweats, vaginal dryness, and the loss of bone mass that may lead to osteoporosis.
 
Funtion:
Estradiol is a form of estrogen, a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body.
Estradiol is used to treat symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation. Other uses include prevention of osteoporosis in postmenopausal women, and replacement of estrogen in women with ovarian failure or other conditions that cause a lack of natural estrogen in the body. Estradiol is sometimes used as part of cancer treatment in women and men.Estradiol may also be used for other purposes not listed in this medication guide.
 
Hormonal contraception:
A chemical derivative of estradiol, ethinyl estradiol with maximum dosage 200 µg, is a major component of hormonal contraceptive devices. Combined forms of hormonal contraception contain ethinyl estradiol and a progestin, which both contribute to the inhibition of GnRH, LH, and FSH, which accounts for the ability of these birth control methods to prevent ovulation and thus prevent pregnancy. Other types of hormonal birth control contain only progestins and no ethinyl estradiol.
Hormone replacement therapy:
If severe side effects of low levels of estradiol in a woman's blood are experienced (commonly at the beginning of menopause or after oophorectomy), hormone replacement therapy may be prescribed. Such therapy is usually combined with a progestin to reduce the risk of endometrial cancer.
Estrogen therapy may be used in treatment of infertility in women when there is a need to develop sperm-friendly cervical mucus or an appropriate uterine lining. This is often prescribed in combination with clomifene.
Estrogen therapy can also be used to treat advanced prostate cancer, as well as to relieve symptoms of breast cancer.
Not all products are available worldwide. Estradiol is also part of conjugated estrogen preparations, such as Premarin, though it is not the major ingredient. (Premarin consists of a large number of estrogen derivatives. As the name indicates, it comes from pregnant mares' urine.
 
Hormone replacement therapy in transgender women:
Main article: Hormone replacement therapy (male-to-female)
Estrogen therapy is also used as part of the hormone replacement therapy for trans women. Either oral or transdermal estradiol is used in higher concentrations during initial treatment and transition; estradiol is continued in lower doses to maintain female-level hormones following gender reassignment surgery.
 
Blocking estrogens:
Inducing a state of hypoestrogenism may be beneficial in certain situations where estrogens are contributing to unwanted effects, e.g., certain forms of breast cancer, gynecomastia, premature closure of epiphyses, and inhibiting feminization in female-to-male transsexual hormone treatment. Estrogen levels can be reduced by inhibiting production using gonadotropin-releasing factor agonists (GnRH agonists) or blocking the aromatase enzyme using an aromatase inhibitor, or with an estrogen receptor antagonist, such as tamoxifen.

Steroid Cycle
1, Front end loading-this cuts down on wasted time in the beginning of your cycle waiting for the doses to reach full therapeutic levels . The use of orals in the beginning of a cycle is a popular component of a cycle. While it is not a necessity, it too is a (different) type of front end load. For the advanced Bodybuilder, Dbol should be taken in the beginning of a cycle as well as loading the injectables since the anabolic response from Dbol is alleged to be by a different mechanism than most injectables. If one had to chose between a Dbol load and and injectable load, in most cases, the injectable load should be preferred over the Dbol load.
2, Injection frequency- This is crucial to obtaining even blood concentrations of androgens. Ideally, the more often injected, the better. An acceptable rule of thumb is "inject at half of the half life." For instance, if the half life of a steroid is 7 days, this should be injected at least twice weekly. For cycles that involve multiple injectables, the injections should be fractioned out and divided up based on the injectable with the shortest half life. For instance, if you were doing a test propionate and deca cycle, the old school way to do it would be to inject the prop EOD and the deca once a week. Both compounds should not be viewed as separate, but together with total androgen concentration taken into consideration. If you injected the deca only once a week, probably along with one of the propionate injections, that day will have a much larger spike on total blood androgen concentrations. Instead, the deca should be split up and taken with the propionate injections, EOD. This way there is no one day of the week that has a "spike" and even blood concentrations are maintained throughout the week.
3, Ending the cycle- Switching to shorter esters toward the end of a cycle makes perfect sense however not too many guys incorporate this practice- perhaps because of the lack of variety of drugs. The modern cycle should include replacing long ester injectables with shorter ones so that recovery time is made more efficient. The necessity of switching to shorter esters toward the end of a cycle depends on the type of drugs used. Longer esters such as deca and equipoise should be replaced with shorter acting versions of these compounds no later than four weeks before the end of a cycle. Medium length esters such as t-enanthate and cypionate should be replaced no later than three weeks before the end of a cycle. A couple examples of appropriate replacements are: trenbolone acetate and testosterone propionate. There is no need to "load" these compounds in the middle of a cycle since 1) they are already "fast acting" and 2) blood androgen concentrations are already high.
4, Recovery With the replacement of the faster acting injectables toward the end of a cycle, the "wasted" time between the end of a cycle and beginning of clomid therapy is reduced. For instance, if 100mg TA is used ED, clomid therapy may begin in as little as 5 days after the last shot. This tremendously improves time efficiency. Clomid Or post cycle therapy usually last for four weeks.

When the above recommendations are made, your cycle itself is made much more efficient and if recovery time is made more efficient as well, time "off" AAS may very well be reduced so that the overall efficiency of AAS use over time is tremendously improved.
