PLUS your choice of either:

• Melanotan-I 10mg

• Melanotan-II 10mg

Bacteriostatic Water is also included.

Retatrutide

Retatrutide is a powerful triple agonist peptide that targets GLP-1, GIP (glucose-dependent insulinotropic polypeptide), and glucagon receptors—making it the most comprehensive metabolic peptide in its class. It builds on the progress of earlier compounds like Semaglutide and Tirzepatide by activating three key hormonal pathways involved in appetite regulation, glucose control, and fat metabolism.

This enhanced activity leads to faster, more dramatic fat loss while offering additional therapeutic effects across multiple body systems.

Tesamorelin

Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) that stimulates the release of human growth hormone (HGH). FDA-approved for body fat redistribution syndrome, Tesamorelin has shown powerful effects on fat loss, muscle preservation, nerve regeneration, and cognitive enhancement.

It is not a steroid and does not affect testosterone levels.

Melanotan-I

Melanotan I (afamelanotide-related peptide) is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH). It primarily interacts with melanocortin receptors involved in melanin production and skin pigmentation, which is why it is commonly studied in research relating to melanogenesis, UV responses and pigmentation pathways. Melanotan I is generally considered more selective for the MC1 receptor than Melanotan II and has been investigated for its longer-lasting biological activity compared with naturally occurring α-MSH.

Melanotan-II

Melanotan-2 is an analog of the human peptide alpha-melanocyte-stimulating hormone (a-MSH), that induces skin tanning. It plays a role in stimulating the production of melanin, a pigment that gives color to the skin, hair, and eyes. By increasing the amount of melanin in the skin, Melanotan-2 offers a degree of protection from UV rays, as more melanin in the skin means the skin has a better ability to protect itself from sun damage.

It allows for an accelerated rate of pigment production under much lower levels of UV exposure than would otherwise be necessary. This reduces the time spent under UV light, which in turn helps to prevent skin cancer and sunburn.
