PREGNYL 5000 IU
Pregnyl contains human chorionic gonadotropin which mimics luteinising hormone activity in the body. It is commonly used to support testicular function testosterone production signalling and fertility related processes. In performance focused environments Pregnyl is valued for maintaining testicular responsiveness during or after suppressive anabolic protocols and for supporting hormonal recovery.

Properties and Effects
- Stimulates endogenous testosterone production signalling
- Supports testicular function and volume maintenance
- Assists fertility and sperm production pathways
- Helps preserve Leydig cell responsiveness
- Does not act as an anabolic steroid
Mechanism of Action
Human chorionic gonadotropin binds to luteinising hormone receptors in the testes which stimulates Leydig cells to produce testosterone. This mimics the body’s natural LH signal and helps maintain intratesticular testosterone levels. The mechanism supports hormonal signalling rather than directly supplying testosterone.
Recommended Use
Pregnyl is typically used during hormonal support or recovery protocols depending on individual objectives. It may be applied during suppressive phases to maintain testicular activity or after discontinuation to assist recovery. Proper reconstitution accurate measurement and sterile handling are essential. Use should be structured and time limited.
Safety and Side Effects
Possible side effects include water retention mood changes increased estrogen conversion and testicular sensitivity depending on dosing and duration. Excessive or prolonged use may lead to receptor desensitisation. Individuals with hormone sensitive conditions should use caution. Not recommended during pregnancy or breastfeeding.
Special Notes
Pregnyl is not a testosterone replacement or anabolic steroid. Its role is signalling based and supportive. Proper planning with post cycle recovery compounds and estrogen management improves outcomes. Blood work and hormonal monitoring are recommended during and after use.
Recommended dosage
- 250 to 500 IU per dose
- Typical weekly total is 500 to 1500 IU depending on purpose
Timing of doses
- Inject two to three times per week
- Space doses evenly across the week
- Can be used during cycles or during recovery phases
Practical guidance
Pregnyl is commonly used to support testicular function and maintain natural hormone signalling. Lower and consistent dosing is generally preferred over large infrequent doses. Use sterile technique and keep dosing structured. Monitoring and defined use periods are recommended rather than continuous long term use.

Using Peptide Injectable Vials
STEP 1:VERIFY VIAL INTEGRITY
Inspect both the peptide vial and the bacteriostatic water vial carefully. Check that the caps and seals are intact and have not been tampered with. The contents should appear clear, with no visible particles, cloudiness, or contamination before proceeding.
IMPORTANTINSPECT THE LID
Check both the peptide vial and the bacteriostatic water vial. Locate the small arrows stamped into the gold seal, which indicate the correct opening point. The seal should be opened from the side the arrows point to for proper removal.
STEP 2:LIFT PROTECTIVE CAPS
Gently lift the clear plastic protective cap from the top of the vial. This exposes the gold aluminium safety seal underneath. Take care not to bend or damage the metal seal while removing the plastic cap.
STEP 3:BREAK OFF SAFETY TABS
While lifting the plastic cap from the side indicated by the arrows, gently wiggle it left and right until the small metal tear tab snaps. This opens the seal correctly and exposes the rubber stopper without removing the entire aluminium ring.
IMPORTANTMETAL SEAL REMOVED
The gold metal seal should be lifted from the side indicated by the arrows, leaving the rubber stopper clearly visible. The opening should appear clean and unobstructed, with the metal seal removed evenly and without bending into the centre of the vial.
STEP 4:ADD BACTERIOSTATIC WATER
Insert the syringe needle into the bacteriostatic water vial and draw the required amount of liquid. Slowly inject the water into the peptide vial, allowing the liquid to run down the inner wall of the vial to help protect the peptide.
STEP 5:DISSOLVE THE PEPTIDE
Gently roll or spin the vial between your fingers until the peptide is completely dissolved. Do not shake the vial, as vigorous shaking may damage the peptide structure and reduce its stability.
STEP 6:MEASURE REQUIRED DOSE
Insert the syringe into the vial and draw the required dose through the rubber stopper. Store the mixed solution in a refrigerator and use it within 30 days after mixing.
