Description
Intended Use:
HCG is intended for research purposes only. Reconstitution with bacteriostatic water (BAC water) is required before use.
Storage:
Store lyophilized powder in a cool, dry place away from light. After reconstitution, keep refrigerated at 2–8°C.
Solubility:
Reconstitute with BAC water. Gently swirl to dissolve—do not shake.
Vial Size:
Lyophilized powder in multi-dose vial (commonly supports up to 3ml reconstitution).
Shelf Life:
Lyophilized: up to 24 months
Reconstituted: recommended use within 4–6 weeks
Handling:
Use sterile techniques to maintain product stability and integrity.
Hormonal Regulation Studies
Research shows that HCG can stimulate endogenous testosterone production by acting on the testes, making it widely studied in hormone regulation models.
Reproductive Function Research
HCG has been investigated for its role in supporting reproductive system activity, including spermatogenesis in preclinical and clinical studies.
Endocrine Recovery Models
Studies suggest HCG may help restore natural hormone production in models where endogenous signaling has been suppressed.
HCG works by mimicking the body’s natural luteinizing hormone (LH):
- Stimulates Leydig cells in the testes → increases testosterone production
- Maintains hormonal signaling pathways → supports natural endocrine function
- Supports reproductive processes → contributes to sperm production
Because it acts as a signal hormone, HCG does not replace testosterone directly—it tells the body to produce its own.
