Gonadorelin (GnRH) Peptide

Gonadorelin (GnRH) is a decapeptide gonadotropin-releasing hormone agonist.[1] It appears to work by stimulating the synthesis and release of luteinizing hormone and follicle-stimulating hormone. It is being researched within the context of infertility and reproductive systems, and hypogonadism. It is also studied for its potential as a diagnostic tool to assess pituitary function.[2]

Gonadorelin Research

Gonadorelin Research and Breast Cancer
Research studies in Gonadorelin and ovarian cancer have suggested that the peptide may exhibit the potential to mitigate the onset of certain cancers via estrogen production regulation.[3] Scientists report that “Fusion of GnRH to hpRNase1 structure produced an enzyme, which could specifically target tumor cells.”  [4] Prolonged studies in animal research models of breast cancer have suggested exposure to Gonadorelin may reduce risk of cancer cell proliferation by up to 70%, depending on duration.[5] Studies have also suggested that estrogen-inhibiting measures may reduce disease progression by 50% if the cancer is estrogen-sensitive. Cancer cells are considered to develop resistance over time, usually resulting from increased expression of estrogen receptors. Gonadorelin may directly reduce the growth of estrogen-sensitive cancers and increase receptor efficacy, as posited by researchers.[6] Studies in research models of hyperandrogenism have suggested further that long-term GnRH exposure may lower total estrogen levels and reduce the risk of breast cancer cell growth and proliferation. [7]

Gonadorelin and Prostate Cancer
Exposure to GnRH in research models of prostate cancer began in 1979. Researchers observed that some androgens are formed locally in the prostate through a mechanism called intracrinology.[8] The posited that GnRH acted as a blockade, and appeared only partially effective in mitigating prostate cancer cell growth and proliferation.

Gonadorelin and Dementia
Scientists consider that Luteinizing Hormone (LH), may act on the brain in ways beyond what is typically associated with the hormone, such as sexual dimorphism and fertility. Indeed, increased LH levels have been suggested to hold a positive correlation with incidences of Alzheimer’s disease and reduced memory capacity. Rats exposed to greater LH levels exhibited poor memory and hippocampal dysfunction. This was a defect that was apparently remedied by the influence of LH blockers.[10] Further research on LH observe that higher hormone levels are associated with increased neuropathology. In particular, LH has been suggested to promote the formation of plaques associated with Alzheimer’s disease.[11] The researchers conclude that “Reducing the LH levels by treatment with gonadotropin-releasing hormone agonists could provide [numerous] benefits.” Therefore, researchers assume that lowering LH levels may help slow the progression of Alzheimer’s disease. Testosterone is considered beneficial for maintaining cognitive function. Therefore, blocking the entire hypothalamus-pituitary-gondola axis may not always be recommended for mitigating Alzheimer’s disease. For this reason, scientists have sought to test Gonadorelin derivatives to see if selective disruption of LH production is possible.[12] One ongoing study suggests that Leuprolide, a common substance used with uterine fibroids and GnRH receptor agonists, has been suggested by researchers to potentially reduce the risk of Alzheimer’s disease compared to other Gonadotropin analogs. In this situation, Leuprolide may possibly offset the risk of CAB for Alzheimer’s disease. In particular, researchers studied the apparent ability of Leuprolide to downregulate serum gonadotropin levels (especially LH) and found it generally sufficient to offset the effects of decreased testosterone.[13] Researchers are currently working to understand how the genetic interactions of Alzheimer’s disease may be disrupted. Gonadorelin is an important peptide in this study.

  1. Mariana Wopat

    I have recommended this to all my colleagues! thumbs up

  2. Sunil Ghuptkur

    Biotech comes highly recommended. Even when I experienced problems with emails not arriving in my Hotmail account, customer care was fast to reply. They assured me that the money had been received and that the package would arrive the following day.

  3. Chee Nguyen

    Like that there’s a lot of information about each peptide. Very educational and helpful when picking out products.

  4. Robert Lesner

    Thanks for offering different payment options and the next business day delivery guarantee. My card kept getting declined so I paid through the Paypal link Taylor from customer service emailed me. Much appreciated.

  5. Brian S. Brian S. Casselberry

    There was this one time one of the bottles came a bit cracked. There was no liquid spill at all and everything was fine, but I was still a bit skeptic so I called CS and they told me the bottle is fine, but they’re still gona sent another one, because safety first and why risk it. I loved that and made me really trust them.

  6. Gerald Nila Jr

    ¡Increíble compañía! recomendé a todos

  7. Lisa Berglund

    They came highly recommended by a friend and after shopping with them i see why!

  8. Brian Lewis

    My company has done business with them for a very long time now and we are very pleased and intend to continue choosing Biotech for our peptide needs

  9. Brett Denver

    Everything, from beginning to end, is absolutely flawless

  10. Aleksey Chernyakhovsky

    Had to wait a few days until this product was back in stock but once they got it they sent it over asap. Happy with the service.

  11. Jon Lewis

    Really good products

  12. Austin Bishop

    First found out about Biotech a few months ago, explored their site but wasn’t interested in purchasing at the time. Now had a need for a few peptides with a new project and decided to revsisit and see what they had in stock. Luckily had whatever I needed. Process was basic and easy, not much to it. Everything came in about a span of 24 hours. Pepetides check out and i’ll probbaly purchase from them again.

  13. Stephen Webb

    I love BP’s packaging quality. I know packaging and stuff like this is not that big of a deal compared to the quality of the products, but I’ve gotten vials from other companies where the label was falling off the glass. Not tryna be rude or something but how are you gonna trust the quality of a peptide when the quality of the packaging glue is questionable? Just a thought

  14. Brayden G.

    Standard process of payment and product retrival. Products check out in in regards to purity.

  15. Mike Knowls

    Like how they package everything safely!

  16. Todd Web

    I have noticed they run out of products quick. I also noticed they restock just as fast.

  17. Marcus Downey

    They stock up pretty quickly! I had to place an order last week but they were out of the peptide I needed. Noticed they restocked on a lot of products a few days later.

  18. Janet Heughs

    Their peptides are top teir quality. Their employees are as good as the products they sell. My only comment again is I wish they were a smidge quicker on restocks.

  19. Amy Larson

    Can’t say enough good things about this company. Consistent with their products and great work ethic with their employees.

  20. Reg Sneed Jr.

    Storage life on these are outstanding.

  21. Danny scott

    Biotech Peptides has got to be in my top 3 peptide suppliers. They get my peptides in safe and on time. Peptides are of good quality as well!

  22. Deniz Burduroglu

    Got a 10% off code after my first purchase which was nice.
