Tanexin - Melanotan 2

Melanotan 2 profile:

The synthetic cyclic heptapeptide, Melanotan II (also known as Tanex or MT-II, developed at the University of Arizona) an analogue of alpha-melanotropin, is a receptor agonist of the Melanocortin peptide hormone, α-melanocyte-stimulating hormone (α-MSH), that stimulates the body to make melanin. Melanocortin peptides are neuropeptides derived from the precursor molecule pro-opiomelanocortin (POMC) by tissue-specific splicing; they include adrenocorticotropic hormone (ACTH) and a-melanocyte-stimulating hormone (a-MSH).1

Clinical trials have shown that MT-II safely promotes melanogenesis and aphrodisiac effects. As a result is has a potential to be developed into a tanning and libido increasing preparation. There have also been many studies on MT-II and its effectiveness as: being neurotrophic and neuroprotective; being able to increase insulin sensitivity, improve glucose tolerance as well as decrease food intake and lower body weight.1

Melanin, the dark pigment of a tan, is known to protect the body from skin damage caused by exposure to ultra-violet (UV) radiation. MT-II induces a protective tan without the need to expose the skin to harmful levels of UV radiation. Using potentiometric titration and ultraviolet (UV) spectrophotometry, MT-II has been previously evaluated for the prevention of sunlight induced cancers without the use of chemotherapy.1

Studies, alternating MT-II with Saline (placebo), for 2 consecutive weeks yielded interesting results. Mild nausea, not requiring antiemetic treatment, was reported at most MT-II dose levels as well as the onset of spontaneous, penile erections which were intermittently experienced for l-5 hours after MT-II dosing, depending on the MT-II dose. After 1 week of dosing, patients had increased pigmentation in the face and upper body. Such results demonstrate that MT-II has tanning activity with only 5 low doses every other day by subcutaneous injection.1

Alpha-melanocyte stimulating hormone (α-MSH) is a linear, tridecapeptide which is synthesized and secreted by the pars intermedia of lower vertebrate pituitary glands. α-MSH lacks corticotropic activity and instead, is used to control integumental coloration by binding to melanocortin (MC) receptors on the plasma membranes of melanocytes in the skin.2

MT-II chronically reduces body weight, without the need of long term calorific restriction.3 Obesity is characterized by increased body fat stores resulting from an imbalance between energy intake and energy expenditure. Increased adiposity causes insulin resistance. Type 2 diabetes mellitus (DM) develops when the increased demand for insulin is not compensated due to impaired pancreatic beta cells. Fat accumulation is the primary cause of insulin resistance, although studies show that the central nervous system also plays a critical role.4

The central melanocortin system is a critical regulator of energy homeostasis. Pharmacological and genetic studies have revealed pivotal roles for the central melanocortin pathway in the regulation of satiety and energy expenditure. The melanocortin receptors 3 and 4 (MC3/4 receptors) are required for optimal function of the central melanocortin system.3 These receptors regulate appetite along with numerous metabolic pathways, including thermogenesis, and lipolysis. The α-melanocyte-stimulating hormone (α-MSH) is the endogenous agonist ligand for the MC3/4 receptors. The more stable synthetic melanocortinergic peptide is the MT-II, a non-selective agonist of MC receptors.

There is evidence supporting MTII as a long-term modulator of energy balance, e.g. it can suppress appetite therefore, it may help combat obesity.3 MT-II also increases insulin sensitivity, improves glucose tolerance4, as well as being neurotrophic and neuroprotective.5

Effects of peripheral administration of MT-II, on insulin sensitivity and glucose tolerance were previously examined.4 Subcutaneous administration of MT-II had decreased food intake and body weight in OLETF rats. MT-II group showed more sensitivity to insulin compared with that allowed to eat at libitum or pair-fed group in insulin tolerance tests on day 9.4

MT-II can significantly enhance the recovery of sensory function following a crush lesion of the sciatic nerve.5 In addition, it has been also observed to possesses neuroprotective properties, as it partially protects the nerve from a toxic neuropathy induced by cisplatin.5

Several of the melanocortins, including α-MSH, have been shown to improve recovery of function after peripheral nerve damage, as well as after experimental spinal cord injury.

I have ordered this product for years and I have had no issues with this company. However, I ordered 4 weeks ago and I have still not received my items due to it been out of stock, which should have been advertised on the website before letting customers buy. I ordered my item and I had to send a email asking why it was taking so long, to then be alerted of this issue that it was out of stock. I have waited 1 month for my products and I have had to email constantly to get any update on my order. I have requested a refund and sent my details over. I'm still yet to receive a refund. I am very disappointed in the service I have received as I have ordered from this company for 3 years and I have been a loyal customer. Poor communication all round. I have not been left with a bill and no item.
SELLER RESPONSE: Sorry for the inconvenience caused. We are looking into your order and will sort it out for you. Also, we are changing the management, therefore, this should not happen again.

Melanotan 2

I dont use this product that often, only once a year for my main holiday.

But with trying a few different companies this product is definitely the best out there.

I am fair skinned & do not tan on sunbeds or in the sun, this product gives me a really dark tan & i always keep my colour for at least a few months after the holiday, even although i do not use anymore than 1 vial.

Take small doses to start for first few days incase of nausea but i 100% recommend buying this product & also buying from this company.
