HCG
Price range: €360.00 through €640.00
HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone naturally produced by the placenta during pregnancy. It is a close analogue of LH (luteinizing hormone) and binds to the same receptor — making it the standard research tool for studying LH receptor activation and gonadal hormone production. Supplied as lyophilized powder with ≥98% purity (HPLC-verified).
How It Works
HCG activates the LH receptor on Leydig cells in the testes and theca cells in the ovaries. In men, this directly stimulates testosterone production. In women, it supports progesterone production and ovulation. Because HCG has a much longer half-life than LH itself (36+ hours vs 20-30 minutes), it provides sustained receptor activation.
Research Data
- Testosterone production: HCG directly stimulates Leydig cells to produce testosterone. Research shows significant increases in serum testosterone levels in hypogonadal models.
- Fertility: In both men and women, HCG is a central component of fertility treatment — supporting sperm production in men and triggering ovulation in women.
- Testicular function: Maintains testicular size and function in situations where natural LH production is suppressed, preserving the hormonal feedback loop.
- Pregnancy hormone: In female research, HCG maintains the corpus luteum and progesterone production, essential for early pregnancy maintenance.
- Weight loss (historical): The HCG diet was a popular weight loss protocol. Modern research suggests weight loss on the HCG diet is due to severe calorie restriction (500 calories/day), not HCG itself.
- Tumor marker: HCG is used as a tumor marker for certain germ cell tumors (testicular, ovarian) and gestational trophoblastic disease.
Research Applications
- LH receptor pharmacology
- Testosterone and steroidogenesis research

Community Buzz
HCG is “the ball-refiller” — the community’s go-to for keeping testicular function alive while on testosterone replacement therapy. When you take exogenous testosterone, your body shuts down its own LH production, which causes testicular atrophy over time. HCG mimics LH, keeping the testes functioning and preventing shrinkage. The community protocol: 250-500 IU, 2-3x per week while on TRT. It’s also used for fertility preservation (maintaining sperm production) and post-cycle recovery (restarting natural testosterone production after steroid cycles).
Why People Are Interested
- Prevents testicular shrinkage on TRT. Mimics LH to keep the testes active and functional.
- Preserves fertility. Maintains sperm production when exogenous hormones would otherwise shut it down.
- Supports natural recovery. Used in post-cycle therapy to restart the body’s own testosterone production.

Shipping & Delivery
All peptide products are shipped directly from our fulfillment center in China.
Delivery Time: 6 to 12 business days worldwide.
Tracking: A tracking number is provided via email once your order has been dispatched.
For any questions regarding your shipment, please contact our support team.
All peptide products are supplied as a lyophilized (freeze-dried) powder in sterile glass vials. Lyophilization preserves the peptide's structural integrity and biological activity during transport and storage. The powder must be reconstituted with an appropriate solvent before use in research protocols.
Recommended Solvent
For most peptide research applications, we recommend using Bacteriostatic Water (BAC) — sterile water containing 0.9% benzyl alcohol as a bacteriostatic agent. BAC water helps maintain sterility after reconstitution and is suitable for multi-dose research protocols.

Reconstitution Protocol
- Prepare: Clean your work surface and ensure all materials (vial, BAC water, syringes) are handled in a sterile manner.
- Calculate: Determine the desired concentration by dividing the peptide mass (mg) by the volume of BAC water added (mL). For example, adding 2 mL of BAC water to a 5 mg vial yields a concentration of 2.5 mg/mL.
- Reconstitute: Using a sterile syringe, draw the calculated volume of BAC water. Insert the needle through the rubber stopper at an angle and slowly inject the solvent down the inner wall of the vial — avoid directing the stream directly onto the powder to prevent foaming.
- Dissolve: Gently swirl the vial (do not shake) until the powder is fully dissolved. Most peptides dissolve within 1-2 minutes. A clear, colorless solution indicates complete dissolution.
- Aliquot: For long-term use, transfer the reconstituted solution into sterile aliquots to avoid repeated freeze-thaw cycles of the original vial.
Post-Reconstitution Storage
- Store reconstituted peptide solution at 2-8°C for short-term use (up to 7 days).
- For extended storage, aliquot and freeze at -20°C. Avoid repeated freeze-thaw cycles.
- Always label aliquots with peptide name, concentration, date, and storage conditions.
Note: The optimal solvent and reconstitution protocol may vary depending on the specific peptide and research application. Researchers should consult peptide-specific literature for solubility guidance.
