Mechanism

Oral-stable BPC-157, typically formulated as the arginate salt, retains the same mechanism as standard BPC-157 — promoting angiogenesis via VEGFR2/PI3K/Akt/eNOS and Src-Caveolin-1-eNOS pathways, enhancing nitric oxide production, and stimulating tendon fibroblast growth and collagen formation. The arginate salt provides a protective buffer against gastric acid degradation, maintaining peptide integrity across a wider pH range. BPC-157 demonstrates remarkable native stability in human gastric juice (24+ hours), and the arginate form reportedly achieves 7-fold greater oral bioavailability compared to the acetate salt in preclinical studies.

Tesamorelin

Peptides

Mechanism

Tesamorelin is an FDA-approved synthetic 44-amino acid GHRH analog with a trans-3-hexenoic acid modification at the N-terminal tyrosine that confers resistance to DPP-IV degradation. It binds GHRH receptors on anterior pituitary somatotrophs, stimulating endogenous GH production and secretion while maintaining pulsatile release patterns. Tesamorelin selectively reduces visceral adipose tissue (15-20% reduction in trials) while preserving subcutaneous fat, and markedly increases plasma GH and IGF-1 levels with once-daily dosing.

Standard Dosing

Research indicates 2 mg administered once daily via subcutaneous injection (FDA-approved dose for HIV lipodystrophy).

Timing

Morning administration on empty stomach. Consistent daily timing recommended.

Cycle Duration

26+ weeks in clinical trials. Long-term use is common; effects are not sustained after discontinuation.

Side Effects

  • Injection site reactions (erythema, pruritus)
  • Arthralgia
  • Peripheral edema
  • Myalgia
  • Paresthesia
  • Elevated blood glucose

Contraindications

  • Active cancer or pituitary tumors
  • Pregnancy (Category X)
  • Hypersensitivity to GHRH analogs
  • Disruption of hypothalamic-pituitary axis from surgery/radiation
  • Active cancer
  • Pregnancy
  • Pituitary surgery or disease
