Oxytocin Peptide

Oxytocin is a small peptide comprising only nine amino acids, produced in the hypothalamus and secreted by the posterior pituitary. It has also been isolated from placenta, ovaries, testes, adrenal glands, thymus, retina, and pancreas. The active hormone is obtained by proteolytic cleavage of a larger precursor protein. It is no longer considered merely a neurohypophyseal hormone as its effects are considered to be far-reaching and include interaction with additional peptides. Oxytocin appears to be a protein with two independent natural functions. First, it appears to act as a neuropeptide produced by the hypothalamus to regulate bonding, reproduction, and birth. Oxytocin appears to be not only bloodborne but also secreted by the placenta of pregnant animals to influence birth, milk production, and bonding with their young. Small amounts of the protein produced from testes appears to promote mating behavior and pair bonding.

Oxytocin Research

Oxytocin and Wound Healing
Oxytocin appears to regulate inflammation through inflammatory cytokines. Increased social interaction in one research model was observed to trigger Oxytocin (Pitocin) level, which researchers speculated may heave lead to faster tissue repair and wound healing. Similarly, studies in hostile equations between animals appears to suppress oxytocin production and delays wound healing, potentially by up to 40%.[1] The researchers conclude that “These data confirm and extend prior evidence implicating oxytocin and vasopressin in couples’ positive and negative communication behaviors, and also provide further evidence of their role in an important [variable].” These hostile couples also exhibited reduced IL-6, tumor necrosis factor-alpha, and IL-1beta at the wound site.[2]

Oxytocin and Cardiovascular Risk
The hormone has been speculated to protect cardiac and vascular systems. It may act to dissipate and burn off fat cell accumulation, influence blood pressure and glucose intolerance, and potentially block or mitigate secretion of stress hormones.[3] These factors may influence cardiovascular disease (CVD), and thus Oxytocin (Pitocin) may be an potential agent in the study of CVD. Reduced Oxytocin receptors may cause atherosclerosis.[4] The scientist report that “The major pathophysiological basis of CAD is atherosclerosis in association with varieties of immunometabolic disorders that can suppress oxytocin (OT) receptor (OTR) signaling in the cardiovascular system (CVS).” Oxytocin exposure appears to overcome the drawback of reduced receptor density and helps maintain cardiac integrity. Exposure of peptide in hearts of rats during a heart attack appeared to assist in preventing cellular death of cardiomyocytes. Jankoski et. al. suggested that late-term development of dilated cardiomyopathy may be addressed by chronic Oxytocin (Endopituitrina) treatment. It also appears to help to prime the cardiac stem cells for “tissue regeneration through direct differentiation, secretion of protective and cardiomyogenic factors, and/or their fusion with injured cardiomyocytes.” It further appears to mitigate cases of cardiac damage due to diabetes in mice. The fat accumulation in these mice was reported to be reduced by 19%, and the fasting glucose levels by about 23%. Oxytocin (Endopituitrina) appears to increase insulin resistance in the animals, possibly establishing proper systolic and diastolic functions over control animals leading to decreased cardiomyocyte hypertrophy, fibrosis, and apoptosis.[5] It appears to protect against ischemic injuries in other tissues as well apart from the heart. Rats with priapism indicate the potential action of Oxycotin (Pitocin) against ischemia-reperfusion injury by reducing nitric oxide levels.

Oxytocin and Diabetes
The peptide appears to improve glucose uptake by skeletal muscles via boosting insulin sensitivity. It further may enhance lipid utilization, dyslipidemia, and body fat mass reduction. Oxytocin deficiency has also been suggested to correlate to body mass, irrespective of external factors, suggesting its role in energy homeostasis.[6] Oxytocin appears to affect insulin, glucose, and body composition in obese mice but not in lean mice. Research observations suggest that the peptide might be impactful only in very certain conditions. The backdrop of diabetes appears to trigger different effects on diabetes models compared to controls.As per Barengolts, “circulating oxytocin is lower in type 2 diabetes versus normoglycemic subjects and negatively correlated with glycosylated hemoglobin A1C and insulin resistance.

Oxytocin and Cognitive Performance
Maternal deprivation may cause irreversible cognitive and behavioral functioning changes. Mice models suggest Oxytocin changes due to less parental bonding may be a prominent cause. Oxytocin exposure in maternally deprived mice appeared to increase hormone levels for neuronal development in the prefrontal cortex. Overall behavior appeared to remain constant, but the cognitive ability was observe to be improved in the cohort exposed to Oxytocin.[7] Intranasal Oxytocin may improve learning in mice in the backdrop of stress.

Oxytocin Peptide Research and Anxiety
The hormone has been studied for its potential to minimize anxiety and depression. The genetic polymorphisms in the Oxytocin (Endopituitrina) receptor gene appear to cause social anxiety disorder and problems with attachment in childhood. Animals exhibiting chronic anxious behavior have also displayed epigenetic changes in the Oxytocin receptor.[8] This indicates a possible compensatory pathway for pathologically suppressed Oxytocin levels. This indicates that social anxiety may be partially triggered by diminished Oxytocin signaling. Oxytocin dysregulation may lead to borderline personality disorder (BPD) as well. BPD is extremely challenging and has significant short- and long-term impacts; therefore, Oxytocin may help understand the pathology leading to better treatment.

Oxytocin and Hunger
Research in a condition (Prader-Willi syndrome) marked by uncontrolled appetite has suggested that at least part of the pathology may result from increased suppression of Oxytocin (Pitocin) signaling.[9] Therefore, Oxytocin (Endopituitrina) has been suggested to play a potential role in regulating hunger state and feeding behavior.

Oxytocin and Old Muscle
Oxytocin also appears to regulate muscle maintenance. Age-associated reduction in molecule levels appears to lead to muscle wasting (sarcopenia). The research carried out at Berkeley suggests that both blood levels of the peptide and its receptors on muscle stem cells decrease over time. Exogenous use of Oxytocin appears to allow muscles to recover much of their healing potential. According to Elabd, one of the authors of the research, “repair of muscle in the old mice was at about 80%” compared to younger mice after Oxytocin was presented. Thus it can be potentially studied in relation to organ degeneration further, it may possibly slow down dysfunction.

  4. Laron Hall

    This was my second attempt at ordering peptides from an online supplier, Im just glad I actually recieved my order. My first attempt didnt go so well and I had to file a chargeback because I never received the products. thanks for the top notch service.

  5. Velvet Viper

    For Growth hormone secretagogues, this is my go-to vendor. Getting in contact with the company was smooth and quick.

  6. Avani Ross

    First-time customer. Ordering was easy, needed one product that is out of stock. Will see how this first-order goes and then maybe try again with the product that was out of stock as well.

  7. Sebastian Cook

    They’re a little smaller than I imagined, still good though! wish it was a little bigger.

  8. Lea Ceasrine

    they are really great at making the customer feel heard and the whole “customer is always right” motto. called and let them know my stuff was late and feels like because of that the peptides were damaged. didn’t argue or give me a hard time. they sent out new ones. it was relieving because I’ve had other companies just leave me stranded with nothing. so real nice service and this time stuff came in a day.

  9. Jeremy Chidester

    Haven’t needed a peptide they didn’t have yet. Very large range of products

  10. Peilin Hu

    海關無問題 純正貨品

  11. Dylan Lou

    I have tested the peptides out, and they are legitimate. They help my research floruish and I see more of a difference with these peptides then with my previous supplier.

  12. Brett Loewenstein

    They came highly recommended by a buddy of mine at work. I see what all the rave is about. Good stuff!

  13. Dennis Burcaw

    Stuggled to find a permenant peptide supplier. I belive my struggle has ended. Incredible company.

  14. Aaron Grant

    My peptides came in quickly and safley! Packaging was great and didn’t feel like the peptides would be unsafe.

  15. Eric Wilson

    The peptides are proving themselves to be of the highest quality. I have used different companies in the past few years and nothing compares to Biotechs bunch.

  16. Jon L.

    They came highly recommeneded by many so had to test them out. From my expeirnce everything that’s been reported to me is ture. They do have great cutomer service, I think I had been going back and forth with taylor. Did not wait long for responces and my package came in less than 2 days. Nothing was broken but have seem some reviews stating it could happen, so i’ll be on the lookout for a potential situation. All is good with biotech however.

  17. Allie Thompson

    I was struggeling To place my order as it seems the site was glitching. I eventually was able to order it but seems strange that was happening.

  18. marc dennings

    There’s no where else i’d suggest to anybody looking to purchase peptides.

  19. Liz Brooks

    Reading their up-to-date blogs is something I look forward to doing. They’re informative and keep me up to date on the newest developments in the field of peptides. There is a particular peptide mentioned in the blog, which saves me time by not having to hunt it up on my own. It’s one of my favorite aspects of the website.

  20. Seth Kluesner

    Exceptional customer service and clear, timely communication are the norm at this company.

  21. josh brooks

    I was concerned about the temperature and making certain that no goods was damaged or wrecked, but they all seemed to be in fine condition to me when I examined them.

  22. Gabe ting

    I think you guys should definitely switch your delivery company. You have amazing products, but you are gonna lose a lot of customers by letting the delivery company ruin your packaging. Not worth it for you

  23. Zachary Kosloy

    Great quality peptides, long shelf life as well when you follow the correct directions.

  24. Nathan Glasswell

    Staff is trained well and were able to help me locate my order that looked to be stuck in transit. Danny was able to send me discount code for my next purchase and even resent this order as the delay would most probably affect the peptides.

  25. Kev Nguyen

    Very happy customer here.

  26. Angelo Mae de Vera

    Very quick process. In and out in a breeze. Very cool

  27. Geroge Boerstler

    Best peptide hormone out there
