Dragon Pharma HCG Human Chorionic Gonadotropin 2500 IU and 5000 IU
Injection · 2500 IU · kit
HCG is human chorionic gonadotropin, a lyophilized peptide hormone supplied in two vials: HCG 2500IU and HCG 5000 IU. It mimics luteinizing hormone and keeps the testes working while a suppressive run is underway, but it does not restart the axis on its own. Both vials are diluted with bacteriostatic water before use.
GMP-manufactured and HPLC-verified, with a COA per batch. Dragon Pharma HCG for sale with U.S. domestic shipping.
Product overview
Dragon Pharma HCG - Human Chorionic Gonadotropin
Human chorionic gonadotropin is a peptide hormone that binds the same receptor as luteinizing hormone and signals the Leydig cells of the testes to keep producing testosterone. In community layouts it sits next to the recovery drugs rather than next to the androgens: Clomid and Nolvadex drive the pituitary side, while HCG works directly on the testes, and the two are used in sequence rather than as substitutes. A testosterone base is what most suppressive runs are built on, which is exactly why the testes need support in the first place.
Variant Comparison
| Variant | Content | Best use |
|---|---|---|
| HCG 2500IU | Single vial of 2500 IU lyophilized powder | Low weekly amounts spread over a longer run |
| HCG 5000 IU | Single vial of 5000 IU lyophilized powder | Higher amounts or a shared vial |
The two options contain the same hormone, so the choice is simply how much powder is needed for the planned schedule. A larger vial means fewer vials on hand, but a reconstituted solution is only stable for a limited time in the refrigerator, which is the argument for buying the size that matches the weekly amount.
How Gonadotropin Works
HCG imitates the luteinizing hormone signal, so the testes keep working even while the pituitary is shut down by an exogenous androgen. That is support, not recovery: the axis is not switched back on by HCG, and it stays off until the suppressive compound has cleared and a SERM takes over. Cited work gives a two-phase half-life, with an initial phase of 6 to 11 hours and a terminal phase of 23 to 37 hours, and about 31 hours after an intramuscular dose.
Dosage & Administration
The powder must be dissolved with bacteriostatic water before use, and the solution is kept refrigerated afterwards. No sports schedule is approved, so the numbers below are community protocols: a common maintenance pattern is 250 IU every other day or 500 IU two or three times a week, and a finishing pattern runs 500 to 1000 IU every other day for two to four weeks. Estradiol is monitored because raising intratesticular testosterone also raises aromatization, and some layouts pair HCG with HMG when fertility is part of the goal.
Quality & Authenticity
Each batch is produced under GMP conditions and checked by third-party HPLC, with a Certificate of Analysis held for the batch. Keep the lyophilized vials cold and dry, and refrigerate the reconstituted solution: do not freeze it.

FAQ
Before you ask
Questions, answered
It is human chorionic gonadotropin, a peptide hormone supplied as lyophilized vials. In community layouts it is used to keep testicular function alive during a suppressive cycle and to prepare for recovery afterwards. It behaves like luteinizing hormone at the testes and does not restart the pituitary signal by itself, so it works with a SERM rather than instead of one.
Both contain the same hormone, so the choice depends on the weekly amount and on how quickly a reconstituted vial will be used. A 2500 IU vial suits low maintenance amounts spread over a longer period, while a 5000 IU vial suits higher amounts or a shared schedule. Only the 2500 IU card is currently shown in stock on the page.
No sports dose is approved, so the figures are community protocols. A common maintenance pattern is 250 IU every other day or 500 IU two or three times a week, run alongside the suppressive compound. A finishing pattern uses 500 to 1000 IU every other day for two to four weeks before the SERM phase starts, once the ester has cleared.
The vial contains lyophilized powder that must be dissolved with bacteriostatic water before injection. Add the water slowly down the inside wall of the vial, swirl rather than shake, and keep the resulting solution refrigerated. Bacteriostatic water is preferred over plain sterile water because its preservative allows the vial to be used over several days.
Raising intratesticular testosterone also raises aromatization, so estrogen-related effects such as water retention or gynecomastia are the ones users watch for, and estradiol is monitored during use. Injection site reactions are reported, and high amounts over long periods are linked with testicular desensitization in community discussion. HCG is not a substitute for a well-planned recovery.
No. HCG mimics luteinizing hormone but does not restore the pituitary signal, so it cannot switch the axis back on by itself. The usual order is HCG while the suppressive compound clears, then a SERM such as Clomid or Nolvadex to restart the upstream signal. Using HCG alone as recovery leaves the pituitary side unaddressed.
Yes. The 2500 IU vial is shown in stock at 90.00 USD for U.S. domestic delivery, while the 5000 IU vial currently displays as out of stock at 145.00 USD. International shipping is marked as currently unavailable on this page, so the U.S. option is the active one. Orders are dispatched after payment confirmation and are intended strictly for laboratory research.
