  • Synthetic peptide triptorelin

    Synthetic peptide triptorelin

    Triptorelin is a synthetic peptide agonist analog of luteinizing hormone releasing hormone (LHRH). Possessing greater potency than endogenous LHRH, triptorelin reversibly represses gonadotropin secretion. After chronic, continuous administration, this agent effects sustained decreases in LH and FSH production and testicular and ovarian steroidogenesis. Serum testosterone concentrations may fall to levels typically observed in surgically castrated men. 

  • Tesamorelin decrease bodyfat

    Tesamorelin decrease bodyfat

    Tesamorelin is made with growth hormone-releasing factor (GRF). Tesamorelin injection is used to decrease the amount of extra fat in the stomach area in adults with human immunodeficiency virus (HIV) who have lipodystrophy (increased body fat in certain areas of the body). Tesamorelin injection is not used to help with weight loss. Tesamorelin injection is in a class of medications called human growth hormone-releasing factor (GRF) analogs. It works by increasing the production of a certain natural substance that can decrease the amount of body fat.

  • Semaglutide Peptide

    Semaglutide Peptide

    Semaglutide is an antidiabetic medication used for the treatment of type 2 diabetes and long-term weight management. In June 2021, the US Food and Drug Administration (FDA) approved semaglutide injection sold  for long-term weight management in adults.It can help someone shed 15% of their body weight.

  • MOTS-c

    MOTS-C peptide

    The mitochondrial-derived peptide MOTS-c (mitochondrial open-reading frame of the twelve SrRNA type-c) is a peptide recently discovered by Lee et al., containing 16 amino acid, and it is expressed mainly in the blood plasma, skeletal muscle and heart, both in rodents and human being11,12

  •  short peptides Thymalin

    Thymalin Peptide

    Thymalin is the polypeptide drug  used for various diseases associated with immune dysfunction, viral and bacterial infections, regeneration normalization, immunodepression, and the depression of hematogenesis after chemical and radiotherapy. The molecular mechanism of the action of thymalin and its components, EW dipeptide (the drug thymogen), the dipeptide KE, and the tripeptide EDP, are analyzed. These short peptides regulate gene expression and the synthesis of heat-shock protein, cytokines, fibrinolysis, gerontogenes, and the differentiation, proliferation, apoptosis of cells. Thymalin and thymogen have practically no side effects and are used for various viral infections.

IGF-1 LR3 insulin like growth factor

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). This peptide is strengthened with a growth factor, IGF, which has insulin-like properties.

IGF-1 LR3  insulin like growth factor


Igf-1 long r3 is an 83-amino-acid analog of human IGF-I actually containing the complete human IGF-1 sequence but with the replacement of an Arg for the Glu at position 3, as well as a 13 amino acid extension peptide at the N-terminus. This makes Long R3 IGF-I significantly more potent ( 2-3x) than IGF-I in studies, because it has a lower affinity to be rendered inactive by IGF binding proteins, and consequently more potential activity in the body. 




Source of active ingredients:
IGF-1 plays a significant role in muscle regeneration. Although IGF-1 induces differentiation to a much greater degree, it stimulates both proliferation and differentiation of stem cells in an autocrine-paracrine manner.
When IGF-1 is injected locally, it increases satellite cell activity, muscle DNA, muscle protein content, muscle weight and muscle cross sectional area. The importance of IGF-1 lies in the fact that all of its apparent functions act to induce muscle growth with or without overload although it really shines as a growth promoter when combined with physical loading of the muscle.

IGF-1 also acts as an endocrine growth factor having an anabolic effect on distant tissues once released into the blood stream by the liver. IGF-1 possesses the insulin-like property of inhibiting degradation, in addition it stimulates protein synthesis. The insulin-like effects are probably because of the similarity of the signaling pathways between insulin and IGF-1 following ligand binding at the receptors.

The ability of IGF-I to stimulate protein synthesis resembles the action of GH, which was shown in separate studies on volunteers to stimulate protein synthesis without affecting protein degradation. Although it is believed that the effects of GH are mediated through IGF-1, this cannot be the case entirely. First, the effects of the two hormones are different, in that GH does not change protein degradation. Second, the effect of GH is observed with little or no change in systemic IGF-1 concentrations.
