BPC-157

Peptides

Mechanism

BPC-157 is a 15-amino acid peptide derived from human gastric juice that promotes angiogenesis via dual VEGFR2-dependent (PI3K-Akt-eNOS) and VEGF-independent (Src-Caveolin-1-eNOS) nitric oxide pathways. It upregulates growth hormone receptor expression, modulates the FAK-paxillin pathway for cell migration, and counteracts damage to the nitric oxide system. Additionally, it enhances tendon fibroblast growth, promotes reticulin and collagen formation, and accelerates wound healing by mediating the NO system's protective functions.

Standard Dosing

Research indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection near the site of injury.

Timing

Administer on an empty stomach or near the injury site. No strict meal timing required, though fasted state may improve absorption for oral dosing.

Cycle Duration

Typical cycles range from 4-12 weeks depending on the injury being addressed.

Side Effects

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

Contraindications

  • Active cancer or history of cancer (theoretical concern with angiogenesis promotion)
  • Pregnancy and breastfeeding
  • Children under 18

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
