Over hCG
Human chorionic gonadotropin (hCG) is a glycoprotein hormone naturally produced during pregnancy that acts on LH receptors to stimulate gonadal function. It is one of the most extensively studied hormones in reproductive endocrinology, with decades of published clinical data. Researchers use hCG to investigate LH-receptor-mediated processes including testosterone production, ovulation, and gonadal function maintenance.

Researchers use hCG to investigate LH-receptor-mediated processes including testosterone production, ovulation, and gonadal function maintenance.
Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced by trophoblast cells of the placenta. Its alpha subunit is identical to LH, FSH, and TSH; the beta subunit confers specificity. hCG binds to LH/CG receptors on Leydig cells in the testes, activating adenylyl cyclase/cAMP signaling, which stimulates cholesterol conversion to pregnenolone and downstream steroidogenesis (testosterone synthesis). Also supports Sertoli cell function and spermatogenesis. In women, stimulates ovulation via LH-like activity.

FDA-approved (Pregnyl, Novarel); decades of clinical use across multiple indications
Opslag en hantering
Gevriesdroogd poeder: Refrigerated recommended
Na reconstitutie: Refrigerate immediately; use within 30-60 days
Veiligheid en beperkingen
Onderzocht voor: Testicular function maintenance during TRT, Post-cycle therapy, Male fertility preservation, Testosterone production stimulation, Ovulation induction
Gemelde aanvang: Testosterone response within 24-72 hours; testicular volume maintenance ongoing
Gemelde duur: On-cycle: 250-500iu SC every other day (continuous with TRT). PCT: 1000-2500iu EOD for 2-4 weeks. Dosing in IU, not mcg.
Meldingen uit de community: Essential during TRT for fertility preservation. Current Reddit meta: 'Use hCG on-cycle, not as PCT standalone.' Key debate: optimal dose (250iu vs 500iu EOD). Some users report mood improvement and 'fuller' feeling on hCG. Main concerns: estrogen management and proper cold storage after reconstitution.

Human chorionic gonadotropin for management of infertility in hypogonadal men
hCG maintains spermatogenesis in men on TRT and prevents azoospermia. Essential for fertility preservation during testosterone replacement.

hCG concurrent with testosterone replacement therapy
Prevents testicular atrophy during TRT by maintaining intratesticular testosterone at levels sufficient for ongoing spermatogenesis and Leydig cell function.

hCG in post-cycle therapy and Leydig cell restoration
Restores Leydig cell function post-AAS use with dose-dependent testosterone response. Current community meta favors on-cycle use over standalone PCT.

However at that rate I'm using my HCG (from TRT Nation) twice as fast as the rx so need to find a good HCG source. … Yeah I think I’m going to drop it to 250IU’s M-W-F, how long was it until you started feeling any improvements, I just did

Vragen over hCG
Vragen en antwoorden die bij dit product zijn vastgelegd.
hCG is a glycoprotein hormone (not a simple peptide), and its biological activity is measured in International Units (IU) rather than by mass. This is because the biological potency can vary between preparations, so IU standardizes the actual biological effect. A standard vial contains 10,000iu. Typical TRT support dosing is 250-500iu every other day or 3x per week.
Current consensus strongly favors using hCG concurrently with TRT (on-cycle) rather than only for PCT. On-cycle use maintains testicular size, intratesticular testosterone, and spermatogenesis throughout. Using hCG only post-cycle means the testes have already atrophied and recovery takes longer. The typical on-cycle dose is 250-500iu every other day or 3x/week.
Yes. Lyophilized (powder) hCG should be stored refrigerated for best stability. After reconstitution with bacteriostatic water, it MUST be refrigerated and used within 30-60 days. hCG is a large glycoprotein hormone that is more sensitive to temperature than smaller peptides. Never freeze reconstituted hCG.
