HCG with HGH
Studied together once: 8 men with low sperm counts, in 1996.
The receipt
1 study gave them to people together
Human pilots · 1 study, 8 men (1996)
- Evidence on the combination
- Human pilots
What each does alone
- Libido & hormones · Daily shotHCGHormoneMen on testosterone use it to stay fertile. The standard 500 IU every-other-day dose comes from a 2005 study.Approved drugFDA approvedChecked Oct 23

Mechanism overlap · reasoning, not evidence
- HCG
- Hormone — Glycoprotein Gonadotropin (LH analog)
- HGH
- Hormone — Recombinant Human Growth Hormone (rhGH)
Reasoning, not evidence: what each is described to do says nothing about what they do together.
What the studies found
Men with low sperm counts (Anapliotou et al., 1996)
- What was given — 8 men without GH deficiency, three protocols 3 months apart: hCG alone (1,500 IU three times), hCG plus GH 4 IU daily, and hCG plus placebo.
- What it found — IGF-1 rose more than threefold on GH. Seminal IGF-1 did not change, and the steroid response to hCG was the same in all three protocols except for higher progesterone on GH. The authors: a “weak synergist effect on steroidogenesis.”
- Limits — 8 men, short-term.
No study of hCG with HGH for testosterone or physique turned up in PubMed or Europe PMC (searched September 29, 2026).
