What does this video actually claim?
The TikTok from @ukbodybuilding asks "Why HCG so important?" while showing someone handling what appears to be a vial. The hashtags tell the real story: #trt #pct #anabolics #steroids. The creator is talking about human chorionic gonadotropin (HCG) in the context of testosterone replacement therapy and post-cycle therapy for anabolic steroid users.
The video itself is short and doesn't make explicit claims, but the implication is clear from the hashtags. HCG is being positioned as an important adjunct to testosterone therapy or steroid cycles. The creator appears to be suggesting HCG has benefits for bodybuilders and TRT users, particularly around maintaining natural hormone production.
Does the science support using HCG with TRT?
The research on HCG for TRT users is actually pretty solid, though not as straightforward as the bodybuilding community often presents it. Coviello et al. (Journal of Clinical Endocrinology & Metabolism, 2005) showed that HCG at 500 IU every other day maintained intratesticular testosterone levels in men receiving exogenous testosterone.
More recently, Hsieh et al. (European Urology, 2013) found that HCG preserved testicular size and sperm production in men on testosterone therapy. The study used 1500 IU twice weekly and showed maintained fertility markers compared to testosterone alone.
However, the "importance" depends entirely on your goals. If you're trying to maintain fertility or testicular size during TRT, HCG has solid evidence. If you just want symptom relief from low testosterone, the data shows testosterone alone works fine for most men.
What about HCG for post-cycle therapy?
This is where things get murkier because we're talking about illegal anabolic steroid use, which doesn't get studied in controlled trials for obvious reasons. The theory is that HCG can jumpstart natural testosterone production after a steroid cycle by mimicking luteinizing hormone.
Physiologically, this makes sense. HCG binds to LH receptors in the testes and stimulates testosterone production. But the protocols used in bodybuilding (often 5000-10000 IU doses) are much higher than anything studied for medical use.
The medical literature on HCG for hypogonadism typically uses 1500-3000 IU doses, 2-3 times per week. The massive doses seen in PCT protocols aren't backed by research and may actually desensitize LH receptors, which defeats the purpose.
What did the creator get wrong?
The biggest issue isn't what @ukbodybuilding said explicitly, but what the video implies through its hashtag strategy. Presenting HCG as universally "important" oversimplifies a complex decision that depends on individual circumstances and goals.
For standard TRT patients who aren't concerned about fertility, HCG adds complexity and cost without clear benefits. The TRAVERSE trial (Lincoff et al., NEJM, 2023) studied cardiovascular outcomes in 5246 men on testosterone therapy. None used HCG, and the outcomes were generally positive.
The video also sits in that gray area where it's discussing compounds used both medically and illegally. While HCG itself isn't a controlled substance, the context suggests use alongside anabolic steroids, which is a different conversation entirely.
What should you actually know about HCG?
HCG has legitimate medical uses, particularly for men who want to maintain fertility while on TRT. The typical prescription dose is 1500-2000 IU twice weekly, based on studies showing preservation of spermatogenesis and testicular function.
Side effects aren't trivial. HCG can increase estradiol levels significantly, sometimes requiring additional medications to manage. Some men report mood swings or acne flares when adding HCG to their TRT protocol.
The cost factor matters too. HCG adds roughly $100-200 monthly to TRT costs and requires more frequent injections. For men not concerned about fertility, standard testosterone therapy often provides the same symptom relief with less complexity.
