Kisspeptin-10

Peptides

Mechanism

Kisspeptin-10 is the 10-amino acid C-terminal fragment of the kisspeptin family that signals directly to GnRH neurons through the kisspeptin receptor (KISS1R/GPR54), triggering GnRH release into the portal circulation. This stimulates LH and FSH secretion from anterior pituitary gonadotrophs. In men, intravenous kisspeptin-10 produces rapid dose-dependent LH rises (4.1 to 12.4 IU/L at 1 mcg/kg within 30 minutes), increases LH pulse frequency and amplitude, and subsequently elevates testosterone through the HPG axis.

Standard Dosing

Research indicates 1-10 mcg/kg via subcutaneous injection or IV bolus for acute HPG axis stimulation.

Timing

Morning dosing preferred for testosterone optimization. Can be used acutely before sexual activity.

Cycle Duration

Short-term use only. Continuous kisspeptin administration may cause tachyphylaxis (desensitization) of the HPG axis.

Side Effects

  • Facial flushing
  • Mild nausea
  • Elevated LH/testosterone (desired effect)
  • Potential for HPG axis desensitization with prolonged use

Contraindications

  • Hormone-sensitive cancers (prostate, breast)
  • Pregnancy and breastfeeding
  • Children/adolescents (premature puberty risk)

Mechanism

Pentadeca Arginate is a synthetic 15-amino acid peptide utilizing an arginate salt formulation of the BPC-157 sequence, designed to enhance nitric oxide production and promote angiogenesis. It stimulates collagen synthesis, enhances tissue repair through increased tensile strength, reduces inflammation via modulation of inflammatory cytokines, and accelerates cellular proliferation in tendon fibroblasts. The arginate salt form provides superior stability and bioavailability compared to traditional acetate formulations.

Standard Dosing

Research indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection.

Timing

Administer on an empty stomach. Inject near site of injury for localized effect.

Cycle Duration

4-12 weeks depending on therapeutic target.

Side Effects

  • Mild nausea (rare)
  • Injection site irritation
  • Headache (uncommon)

Contraindications

  • Active cancer
  • Pregnancy and breastfeeding
  • Children under 18
