At MedClub we get this question often, mostly because either guys have been on (HCG) for a while and are tired of SubQ injections, or the price; Pregnyl is not cheap. Below is a little Pro/Con to go over the differences and our professional opinion to summarize.

Why you shouldn’t take Testosterone by itself: The answer is safety, longevity, and preserving your bodies ability to continue its natural systems in the face of atrophy. TRT creates a negative feedback loop illustrated below which, if left unchecked, can cause permanent atrophy.

 

 

Pregnyl/Novarel (HCG) Microdoses

• Pros:
• • Direct Stimulation: Acts as a luteinizing hormone (LH) mimic, directly telling the testes to produce testosterone and sperm even while TRT is “shutting them down”.
  • Maintains Testicular Size: Most effective for preventing or reversing testicular atrophy (shrinkage) or PCT in non-medical situations.
  • Well-Studied for TRT: Widely considered the “gold standard” for guys wanting to stay fertile while on therapy, and protect from negative feedback loop.
• Cons:
• • Injections: Requires frequent subcutaneous injections, which may be a hassle.
  • Estrogen Spikes: Can significantly increase aromatization (estrogen levels), sometimes leading to nipple sensitivity or water retention.
  • Cost & Storage: Much more expensive than clomiphene/enclomiphene and requires refrigeration after mixing.

 

Clomiphene or compounded EnClomiphene

• Pros:
• • Oral Convenience: A simple pill taken daily or a few times a week, no shots
  • Inexpensive: Significantly cheaper than HCG and more widely available as a generic or custom compounded tab/capsule
  • Natural Signal: Encourages your brain to send its own signals to the testes via FSH pathway – does not signal LH.
• Cons:
• • Potentially Blocked by TRT: If your TRT dose is high, it may completely overpower clomiphene’s signal to the brain, making it ineffective while on therapy.
  • Emotional Side Effects: Some men report “brain fog,” mood swings, or a “flattening” of emotions.
  • Vision Risks: In rare cases, it can cause “floaters” or blurred vision, which usually requires stopping the drug altogether.
  • Paradoxical Libido: Some guys will see their T-levels rise on paper, but experience a decrease in libido or sexual function

 

Opinion: The personal dosage of each person is most important, when dealing with hormones and the endocrine system in general we find that taking the time to find the correct dosage for each patient will greatly improve the long term effects while reducing side effects. Most men will feel better when micro-dosing HCG in conjunction with their TRT, for men on higher doses the HCG is almost mandatory since direct biological LH stimulation is the only thing that can keep the natural system running. For many patients on lower long term doses of testosterone they can tolerate enclomiphene with no side effects, and enjoy a cheaper cost. It really comes down to the dosage, and the patients receptor sensitivity to androgens and AAS.

We treat testicular hypo-function & long term testosterone supplementation so our methods are designed specifically for men’s longevity, not bodybuilding. A bodybuilding dosage protocol is too high for ANY Hypothalamic-Pituitary-Gonadal (HPG) relation receptor agonist to protect from androgenic negative feedback loops so this article does not apply to that and is not written as a “solve” for that.

 

 

Sub-Topic: What about Gonadorelin?

GnRH on paper and in theory is great, but in our experience we have had nothing but negative feedback from our clients, shrunken testes, low sperm count, low volume, low libido, and varied side effects. It was popularized when the FDA banned biological compounding of HCG a few years ago so clinics scrambled to find an alternative instead of switching to Pregnyl/Novarel which are pricey brand names for HCG. HCG is derived from pregnant women’s urine so you can imagine why the FDA would want a strict chain of custody on the ingredients. In any case, based on the difference in effectiveness our clients decided paying up for the Pregnyl was simply worth the extra cost. Some guys probably do fine on gonadorelin but those patients would probably be fine using Enclomiphene as well. which is even less expensive and more widely available. The importance of “personal dosage” cannot be understated.
