HCG - Generic Peptides

Buy HCG 5000 IU and 10000 IU by Generic Peptides at XSteroids. HCG stands for human chorionic gonadotropin, a glycoprotein hormone that mimics luteinising hormone and, in men, stimulates the Leydig cells that make testosterone. This is the one product in the peptide catalog that also exists as an approved prescription medicine, so this page separates the two things carefully: the licensed drug with its official label, and the lyophilized research vial sold here. It also covers the unit math, the reconstitution rules and the anti-doping clause that applies to men.

The short version: the substance is real medicine, the vial on this page is not a registered pharmaceutical form, and any dosing decision belongs with the label of an approved product and a doctor.

What HCG Is and What You Are Buying

Chorionic gonadotropin is built from an alpha subunit of 92 amino acids, shared with LH, FSH and TSH, and a beta subunit of 145 amino acids that gives it its own identity. In nature it comes from the human placenta during pregnancy; pharmaceutical versions are extracted from the urine of pregnant women or produced recombinantly.

It binds the same receptor as luteinising hormone. In men that means a direct stimulus to testicular testosterone production, which is why it appears in hormone therapy and, unofficially, in the final phase of a steroid cycle.

The vial on this page is a single glass container of lyophilized powder in a 5000 IU or 10000 IU size, with no diluent supplied: bacteriostatic water is ordered separately. Because the strength is expressed in international units rather than milligrams, the pack is a research presentation, not a pharmacy product with an approved leaflet.

How HCG Works in the Body and on the Label

The licensed medicine

Brands such as Pregnyl and Novarel are approved prescription products, and Ovidrel is the recombinant version. Their labels list specific indications: cryptorchidism in prepubertal boys when there is no anatomical obstruction, selected cases of hypogonadotropic hypogonadism in men, and induction of ovulation in infertile women pretreated with menotropins. Contraindications include precocious puberty, prostate cancer and other androgen dependent tumours, and previous allergic reaction to HCG.

What is sold on this page

The Generic Peptides vials are lyophilized powder in 5000 IU and 10000 IU sizes, sold as research material. They carry no approved patient leaflet, no approved indication and no pharmacy registration in the United States or the European Union. Only the active substance is the same as the medicine; the product form and its regulatory status are not.

What to Expect from HCG

Keep the two products apart. The approved medicine has a label, published pharmacokinetics and a two phase half-life of roughly 6 to 11 hours followed by 23 to 37 hours, and it is used for diagnosed hypogonadism or fertility. The research vial has none of that: no approved indication, no validated shelf life after mixing and no dose any regulator has reviewed. In practice hCG mimics luteinising hormone rather than switching the axis back on, and continuous high doses can desensitise Leydig cells, so it is not a replacement for recovery therapy.

HCG Label Doses and Reconstitution

Units, not milligrams

HCG is dosed in international units, since it is a glycoprotein standardised by biological assay. The approved label for male hypogonadotropic hypogonadism describes 500 to 1000 USP units three times a week for three weeks, then the same dose twice weekly for three weeks, with an alternative long protocol of 4000 USP units three times weekly for six to nine months followed by 2000 USP units three times weekly. Another section of the label lists 5000 USP units every second day for four injections. These are label figures for a diagnosed deficiency, not fitness guidance.

Mixing the 5000 IU and 10000 IU vials

Five millilitres of bacteriostatic water in the 5000 IU vial gives 1000 IU per ml, so 0.1 ml carries 100 IU, which is the 10-unit line on a U-100 insulin syringe. Using 2 ml raises the concentration to 2500 IU per ml, putting 250 IU in those same 10 units, and 1 ml gives 5000 IU per ml with 500 IU per 10 units. For the 10000 IU vial the label pattern is 10 ml for 1000 IU per ml. Run the water down the inside wall and swirl; shaking is avoided because foam damages a glycoprotein.

Storage of the mixed solution

The approved labels say a reconstituted vial must be refrigerated and used within 30 days for one brand and up to 60 days for another. A generic research vial has no such validated shelf life, so the shorter figure is the sensible ceiling. Never freeze the solution.

Stacking HCG in Research Practice

HCG is used at the end of a suppressive cycle because it restores testicular volume and output, and that is the context in which people read about it. The honest limits are worth stating: HCG imitates LH, so it does not switch the axis back on by itself, and continuous high doses can desensitise Leydig cells. Because it raises intratesticular testosterone, aromatisation to estrogen rises as well. Related gonadotropin research uses HMG 75 IU, which supplies FSH activity alongside LH activity, and Kisspeptin-10, which works higher up, at the hypothalamic level. Ipamorelin 5 mg and Sermorelin 5 mg normally cover growth hormone support, while Somatropin 100 IU supplies the hormone directly.

HCG Recovery and Post-Cycle Use

HCG does not replace post-cycle therapy. Its role is to keep the testes working while the axis recovers, and the usual approach is to follow it with a SERM based protocol rather than to use it in place of one. When to stop is a question for blood work, not guesswork: testosterone, LH, FSH and estradiol read together show whether the axis has restarted. This brand sells peptides only, so no SERM products appear here, and anyone running a hormonal cycle should work with a clinician.

HCG Side Effects, Warnings and Legal Status

Reported effects

In women the label lists thromboembolism, cyst rupture, multiple births and ovarian hyperstimulation among the risks, which is why fertility treatment with the drug stays under specialist supervision. For men, the usual effects are reactions at the injection site, water retention, acne and mood swings, and gynecomastia can appear when estrogen rises unchecked.

Anti-doping status

The WADA Prohibited List names chorionic gonadotropin under class S2.2.1, testosterone stimulating peptides in males, alongside LH and menotropin. That ban covers men only and operates at all times, even outside competition. Because it is not something that can be dismissed as an accidental finding, athletes should treat the clause as absolute.

General precautions

Never use the product without a diagnosed medical reason. On the label, contraindications include androgen dependent tumours including prostate cancer, precocious puberty and a prior allergic reaction to HCG. Everything here is research context, not medical advice.

HCG Storage Conditions

The powder is kept at 2 to 8 C away from light, though the label also allows it to be held at room temperature. Once mixed, the vial is refrigerated at 2 to 8 C and used within 30 days. Freezing is not an option, and a solution that has turned cloudy or shows clumps should be discarded.
