Peptides and HGH get discussed as though they were interchangeable approaches to the same goal, and the mechanistic difference between them is the entire reason both categories exist separately in research discussion.
This guide covers what separates growth hormone secretagogue peptides from HGH itself, why that distinction matters, and where Healio’s offering sits. Growth hormone peptide research goes through the class in depth. Nothing here is guidance for personal use.
Peptides vs HGH: supplying versus stimulating
HGH, human growth hormone, administered directly supplies the hormone from outside the body, bypassing the body’s own production and regulatory feedback entirely. Growth hormone secretagogue peptides, such as tesamorelin, work differently, stimulating the pituitary to produce and release its own growth hormone through the normal regulatory pathway.
| HGH | Secretagogue peptides | |
|---|---|---|
| Source of hormone | Supplied externally | Produced by the pituitary |
| Regulatory feedback | Bypassed | Largely preserved |
| Release pattern | Determined by administration | Closer to natural pulsatility |
Why this distinction matters
Growth hormone is released in natural pulses rather than continuously, a pattern that appears to matter functionally. Direct HGH administration produces levels determined by dosing schedule rather than the body’s own pulsatile pattern, while secretagogue peptides are argued to preserve more of that natural pattern by working through the existing regulatory system. That argument and its unsettled status are worth reading in more depth.
Why neither approach is settled science
The core question underlying interest in either approach, whether age-related growth hormone decline represents a deficiency to correct or a regulated physiological shift, remains genuinely unresolved in the research literature. This open question applies to both HGH and secretagogue peptides equally regardless of mechanism.
What Healio stocks and does not stock
Healio does not supply HGH. Healio’s growth hormone secretagogue offering is tesamorelin, which holds approval for one narrow clinical indication, covered fully in the tesamorelin monograph.
Peptides vs HGH: frequently asked questions
What is the difference between peptides and HGH?
HGH supplies growth hormone directly, bypassing the body’s own production. Secretagogue peptides stimulate the pituitary to produce its own growth hormone through the normal regulatory pathway, which is a mechanistically distinct approach.
Does Healio sell HGH?
No. Healio stocks tesamorelin, a growth hormone secretagogue peptide, which works through a different mechanism than direct HGH administration.
Is the secretagogue approach proven better than direct HGH?
The reasoning that preserving natural pulsatility is more physiological is plausible and not conclusively demonstrated as producing better outcomes. The underlying question about growth hormone decline remains genuinely open for both approaches.

A mechanism difference, not a settled verdict
Supplying growth hormone and stimulating its production are genuinely different approaches, and neither comes with resolved evidence about which better serves the underlying goal both are aimed at. The anti-aging collection stocks tesamorelin as a research compound, every batch independently tested before it ships.
