About this peptide

HCG mimics luteinising hormone (LH), the body's own signal that tells the testes to make testosterone. In this space it's best known as what keeps the testes working while someone is on exogenous testosterone, which otherwise shuts that signal down. The same molecule is an approved medicine; supplied here for research use only. Provided as a freeze-dried powder with diluent.

What it does

The main reason people use HCG is to keep the testes active while running testosterone. Exogenous testosterone switches off the body's own LH signal, so the testes shrink and fertility drops; HCG stands in for that signal, helping maintain testicular size, function and fertility through a cycle or on TRT. It's also widely used in post-cycle protocols to help restart natural production.

What to expect

  1. Week 1

    Serum T rises within 2-4 hours of single 1500-5000 IU dose; peaks 24-72 hours; E2 peaks ~24 hours; testicular fullness within 5-10 days at 500 IU EOD

  2. Weeks 2-4

    Visible testicular volume recovery; libido improvement; E2 elevation may emerge

  3. Weeks 4-12

    Sperm return to ejaculate with concurrent SERM by 2-6 months post-AAS (Wenker mean 4.6 months)

  4. Long term

    Continuous moderate-dose hCG preserves ITT/sperm production indefinitely in most users (Hsieh 11-mo follow-up); chronic supraphysiological dosing risks Leydig desensitisation and E2 elevation

A rough guide drawn from research and community reports. Individual results vary and nothing here is a promise.

Key points

Primarily men running a steroid cycle or on TRT who want to avoid testicular shrinkage and protect fertility, plus those planning a post-cycle restart of natural production. The fertility-focused crowd also runs it on its own. A hormonal-axis tool, not a fat-loss, recovery or longevity compound.

HCG mimics luteinizing hormone and activates its receptor on the Leydig cells of the testes, stimulating testosterone production. This is the basis for its use in fertility and hormonal research and for the hCG stimulation test of testicular function.

Reported effects include a rise in estradiol that can bring acne or water retention, and temporary hair shedding at higher amounts; used on its own it suppresses the body's own hormone axis by standing in for the LH signal. As an approved hormone it is supplied for research use only, and potency depends on the diluent and falls over weeks once reconstituted. A Certificate of Analysis is shared where our supplier provides one.

Supplied freeze-dried, usually with a diluent. Reconstitute with the supplied diluent or bacteriostatic water, which gives the longest reconstituted shelf life, then refrigerate and keep out of light. Potency falls over several weeks, so prepare amounts suited to your research timeframe.

Questions about HCG

It acts like luteinizing hormone, signalling the testes to produce testosterone. It is researched in hormonal and fertility contexts and used clinically to assess testicular function.

HCG potency depends on the diluent and handling. Bacteriostatic water gives the longest reconstituted shelf life; potency still falls over several weeks.

Those are prescription medicines, manufactured and regulated as drugs. We supply research peptides for research use, not medicines. We make no therapeutic claims, and nothing here is a substitute for medical care.

Lyophilised (freeze-dried) peptides hold up for a while at room temperature, but heat is the enemy over time. Once reconstituted, keep them refrigerated at 2 to 8°C. We deliver everything cold and include a short storage and reconstitution guide so it's clear.

Yes. Vials arrive freeze-dried for you to mix yourself, which is straightforward and free. If you'd rather not, switch on our reconstitution service and we'll make it up to spec, ready to use, for Rp 100.000 per vial. We can fill pens and cartridges for you too.

Yes, free with every order. We include a 3ml allowance of bacteriostatic water per vial you buy, made up from a mix of our 3ml and 10ml vials so it covers your whole order. Use as much or as little per vial as your protocol needs. Extra is available if you want it.

Message us. We pack every order cold and track it on the way, and if something goes wrong in transit we'll sort it, replacement or re-ship. We don't take your order and disappear.
