Product Overview
Buy HCG 5000 IU by Xeno Laboratories at Best Anabolic Steroids. A single glass vial carries 5000 international units of chorionic gonadotropin as a freeze-dried powder, and every figure on this page belongs to that one vial. The number is quoted in international units rather than milligrams because the substance is standardised by biological activity: what the label describes is what the hormone does in a test system, not how much it weighs on a scale.
The molecule is assembled from two chains. One is a common alpha chain of 92 amino acids that it shares with several pituitary hormones, and the other is a beta chain of 145 amino acids that is unique to it and decides what it does. That outline is what lets it dock at the testis, on the same receptor luteinising hormone uses, and drive testosterone output from the Leydig cells. It copies one signal and nothing more. It does not set the hypothalamic-pituitary-gonadal axis running again, and that limitation is the most important thing to hold on to before reaching for it.
Chorionic gonadotropin is also a registered prescription medicine, sold elsewhere as Pregnyl, Novarel and the recombinant Ovidrel. Only the active substance is shared with those products. The Xeno vial is a research item with no pharmacy registration, bought in practice for two jobs: holding testicular function steady while a suppressive cycle runs, or closing a cycle out before a SERM such as Clomiphene or Tamox takes the handover. When sperm production is part of the goal it is normally stacked with HMG, which supplies the follicle stimulating signal this product does not, and the need itself usually arrives from a long course of the nandrolone or testosterone range where the whole recovery question starts.
Dosage Protocol
The ranges below are drawn from the reference literature and the practice notes collected for this card. They describe the active material, not a prescription, and the correct starting point is the smallest amount that produces the response being tracked.
| Beginner | Low step, 250 IU on alternate days or 500 IU twice or three times a week, for 4-8 weeks |
| Intermediate | Middle step, 500 IU twice or three times a week, or a closing block of 500-1000 IU on alternate days across 10-16 days |
| Advanced | High step, 1000-3000 IU once up to three times a week, kept inside short blocks |
| Female | Nothing validated for the female athlete; inducing ovulation is the clinical use and stays with a doctor |
| Administration | Given under the skin or into a muscle once the powder has been put into solution |
| Duration | Support is matched to the cycle; the closing block lasts about a fortnight |
Mixing arithmetic decides how much each mark on the syringe actually carries. Dissolve the 5000 IU vial in 5 ml of solvent and every millilitre then carries 1000 IU; halve the solvent to 2 ml and the same millilitre carries 2500 IU; cut it to 1 ml and the concentration reaches 5000 IU per millilitre. On a U-100 insulin barrel, 10 units of the 1000 IU per millilitre solution is 100 IU, so the mid-range protocol above asks for a comfortable fraction of a millilitre rather than a full one. Fewer millilitres of water makes the arithmetic easier to read but leaves less room to fine-tune a 250 IU step, so a 2 ml or 5 ml mix is the usual compromise.
Storage follows the same discipline. The powder keeps at 2-8 C with light excluded, and the insert for the reference medicines tolerates room temperature for the unopened vial. Once dissolved, the solution belongs in the refrigerator, never the freezer, and is used within about 30 to 60 days depending on the product it is compared with. Freezing damages the glycoprotein structure and a solution that has been frozen and thawed should not be injected.
Suggested Protocols
This product is never a cycle on its own. Three settings cover how it is actually placed, and in each of them the dose moves with the response rather than staying fixed on paper.
Dose escalation is the part most often handled badly. Continuous high dosing is associated with desensitisation of the Leydig cells, so the advanced range belongs in short blocks with a clear stop date. When estradiol rises on the back of the extra intratesticular testosterone, an aromatase inhibitor from the same line, Arimidex or Aromasin, is the tool for that problem, and it is dosed against a blood result rather than against a symptom.
What to Expect
- Testicular volume usually responds inside the first one to two weeks, which is the earliest visible sign that the signal is landing.
- Serum testosterone climbs within a day of an injection, so a blood draw taken the day after dosing reads higher than one taken at the end of a gap.
- Libido and general well-being tend to move in the first week or two, though they track testosterone and not the gonadotropin itself.
- Estradiol may rise as intratesticular testosterone is produced, showing up as water retention and breast sensitivity at higher doses.
- Nothing about the axis is repaired while the product is in use, so testicular size falls back once it stops unless a SERM follows.
- Local injection reactions are common and short-lived; rotating sites and keeping the technique clean removes most of them.
Side Effects and Management
Post-Cycle Therapy
This product belongs to the recovery window of a cycle but it is not the recovery. It holds or briefly restores Leydig cell output while the suppressive ester clears, and the restart of the axis itself is a SERM job.
Two practical notes close this section. The first is that anti-doping laboratories detect the substance in urine by immunological methods for roughly a week to ten days after a dose, with 5 IU/L as the threshold for an adverse finding, so the window is short compared with the esters being cleared. The second is that the hormone is supplied as an educational and research reference: it is not presented here as a treatment, and a clinician, not a forum thread, belongs in any decision about restarting natural production. Support products from the same range, Arimidex and Proviron, are covered on their own pages for readers assembling the whole recovery picture.
