HCG 5000IU – PharmaQO

HCG 5000 IU Pharmaqo for sale in the UK

HCG 5000 IU by Pharmaqo Labs is pharmaceutical-grade Human Chorionic Gonadotropin, used by anabolic-steroid users to keep the testes producing testosterone during a cycle and to bridge into post-cycle therapy. If you want to buy HCG UK from a verified source, every batch sold here is lab-tested for IU accuracy and dispatched same working day from our UK warehouse.

What is HCG?

Human Chorionic Gonadotropin is a glycoprotein hormone produced naturally by the placenta during pregnancy. Pharmacologically it acts as a near-perfect mimic of luteinising hormone (LH): it binds the same LH/CG receptor on the testicular Leydig cells and triggers them to produce testosterone and maintain spermatogenesis. The active half-life of injected HCG is roughly 24 to 36 hours, which is why on-cycle dosing protocols use a twice-weekly schedule. HCG is the same molecule sold under brand names such as Pregnyl, Eutrig and Puretrig — Pharmaqo simply produces a UFC-grade lyophilised version with a solvent ampoule. It is not an anabolic steroid, does not aromatise directly and does not pass through the liver, so it carries none of the hepatotoxic load of oral compounds.

HCG 5000 IU Pharmaqo benefits

• Prevents testicular atrophy on cycle by keeping the Leydig cells active
• Maintains intratesticular testosterone, which standard TRT/AAS cannot replace
• Preserves fertility and sperm production during suppressive cycles
• Significantly smoother and faster recovery when paired with a SERM-based PCT
• No liver load, no aromatisation directly, no water retention from the molecule itself

Lower, more frequent dosing (250 IU twice weekly) is generally regarded as superior to large weekly bolus shots — it mirrors physiological LH pulses and reduces the chance of receptor desensitisation.

HCG 5000 IU dosage and cycle

On-cycle (testicular maintenance): 250–500 IU twice weekly, run from the start of the cycle until 3–4 days before SERM PCT begins. PCT bridge protocol: 1500–2500 IU every other day for 10 days after the last AAS injection clears, immediately followed by Tamoxifen or Clomid. The 5000 IU vial is reconstituted with bacteriostatic water — at 1000 IU/ml that gives 10 to 20 doses depending on the protocol. Subcutaneous injection (abdomen or thigh) with an insulin syringe is preferred over intramuscular for comfort and absorption. Onset of testicular response is typically felt within a few days. HCG should not be run during active SERM PCT, since the exogenous LH signal will blunt the natural HPTA restart you are trying to achieve.

Side effects and PCT

HCG itself is well tolerated, but it raises endogenous testosterone — and that testosterone aromatises to estrogen. Possible knock-on effects therefore include mild gynecomastia risk, water retention, acne and elevated estradiol if an aromatase inhibitor is not in place on cycle. Very high single doses (over 2000 IU) can cause Leydig-cell receptor desensitisation, which is why blast protocols are no longer first-line. After the cycle and the optional HCG bridge, a standard SERM PCT with Tamoxifen (Nolvadex) Pharmaqo, Clomid Pharmaqo or an all-in-one PCT Tabs Pharmaqo is recommended to fully restore the HPTA.

Stacks well with

HCG 5000 IU pairs naturally with any suppressive AAS cycle. Many UK users prefer the original Organon-brand Pregnyl 5000IU HCG when stock is available and rotate to Pharmaqo or HCG Puretrig 5000IU as drop-in equivalents — the active molecule is identical across all four brands.

Frequently asked questions

How long does HCG 5000 IU take to start working?

Testicular response is usually noticeable within a few days of the first injection, with size and firmness restoring fully over one to two weeks at 250 to 500 IU twice weekly. Blood testosterone elevation from HCG-stimulated Leydig cells is measurable within 24 to 48 hours of the first dose.

Is HCG 5000 IU suitable for first-time users?

HCG is an ancillary, not a primary cycle compound — it is suitable for any user running their first suppressive AAS cycle and is in fact recommended for cycles longer than eight to twelve weeks. It is one of the simplest and best-tolerated supportive compounds available, but it should still be used alongside an aromatase inhibitor and followed by a proper SERM PCT.

Can HCG be detected on a drug test?

HCG is on the WADA prohibited list for male athletes and is detectable in urine for several days to roughly two weeks after a single injection, depending on dose and assay sensitivity. Standard workplace drug screens do not test for HCG, but anyone subject to sport-governed testing should plan washout windows accordingly.
