Peptide

HMG

HMG (human menopausal gonadotropin, or menotropin) is a purified gonadotropin preparation that delivers both FSH and LH activity in a single agent, making it a workhorse of fertility medicine [1]. In women it drives controlled ovarian stimulation for IVF, matching recombinant FSH on live birth rates while adding the LH activity that recombinant FSH lacks [1][2]. In men with hypogonadotropic hypogonadism, HMG paired with hCG restores testosterone and induces spermatogenesis, giving previously infertile patients a genuine path to fatherhood [4][6].

SARM

S-23

S-23 is a high-affinity, orally active selective androgen receptor modulator (SARM) first characterized as a candidate for hormonal male contraception. It binds the androgen receptor as a full agonist and, in animal studies, builds lean muscle mass and bone mineral density while cutting fat, a tissue-selective anabolic profile that has drawn strong interest for body recomposition. It also potently and reversibly suppresses testosterone and sperm production, which is central to both its contraceptive rationale and its cautions.

Hormone

Urofollitropin

Urofollitropin is a purified preparation of follicle-stimulating hormone (FSH) obtained from the urine of postmenopausal women. Used in fertility medicine, it stimulates the ovaries to develop follicles for ovulation induction and for assisted reproduction such as in vitro fertilisation. It has been sold under brand names including Bravelle, Fostimon and Metrodin, and works much like recombinant FSH [1].
