Peptide & Hormone Therapies for Health, Performance & Longevity
Summary
Dr. Craig Koniver, a board-certified physician specializing in “performance medicine,” walks through the clinical applications of peptides and hormones for improving mental health, physical health, and performance. The conversation covers a spectrum from widely known compounds like GLP-1 agonists to lesser-known growth hormone secretagogues and tissue-repair peptides. A central theme is using these tools to augment—rather than replace—the body’s natural hormone systems, while emphasizing physician oversight and clean sourcing.
Key Takeaways
- Peptides sit between lifestyle interventions and direct hormone therapies: They can stimulate endogenous hormone pathways without triggering the negative feedback loops that shut down natural production.
- Microdosing GLP-1 agonists (semaglutide/tirzepatide) at compounded, low doses—targeting no more than 2 lbs of weight loss per week—can largely prevent the muscle loss and “OIC face” associated with standard clinical dosing.
- BPC-157 has been widely used for systemic anti-inflammation and tissue repair; subcutaneous injection outperforms oral dosing even for gut-related issues. It has now been removed from compounding pharmacy lists by the FDA, but Pentadeca Arginate (PDA) is emerging as a closely related substitute.
- Growth hormone secretagogues like ipamorelin (100 mcg max) work best injected at bedtime, without food for ~45 minutes prior, to align with the body’s natural overnight GH pulse.
- Stacking peptides (e.g., ipamorelin + tesamorelin + BPC-157) at lower individual doses can produce synergistic effects on fat loss, lean muscle, sleep quality, and recovery.
- CoQ10 (200 mg/day) and methylated B vitamins are among the few supplements Dr. Koniver consistently recommends, based on their role in mitochondrial electron transport.
- Source quality is critical: Compounding pharmacies are FDA and Board of Pharmacy regulated, require outside purity testing, and produce sterile compounds—unlike gray/black market “research” peptides that often contain inflammatory endotoxins (LPS).
- Testosterone replacement in young men carries real fertility risks; working with a physician to use the lowest effective dose, in physiologically variable delivery forms (injectable vs. pellets), is strongly preferred.
Detailed Notes
What Are Peptides?
- Peptides are chains of 40 amino acids or fewer; proteins are 41+ amino acids.
- The human body produces an estimated 300,000 peptides; only ~150 have been used therapeutically to date.
- Because they mimic or stimulate naturally occurring signaling molecules, they generally do not trigger the negative feedback loops that suppress endogenous hormone production—a key advantage over direct hormone administration.
GLP-1 Agonists (Semaglutide / Tirzepatide)
- Originally FDA-approved for type 2 diabetes glucose management; weight loss was observed as a secondary effect.
- Now prescribed widely off-label for weight loss—a common practice: the majority of drugs prescribed in the U.S. are used off-label.
- Dr. Koniver’s clinical shift: early use often resulted in too-rapid weight loss (15 lbs in 3 weeks), leading to muscle loss and facial fat loss (“OIC face”).
- Preferred approach: Compounded microdose tirzepatide/semaglutide, titrated slowly.
- Target: ≤2 lbs weight loss per week to preserve lean muscle mass.
- Pair with: adequate protein intake + resistance training.
- Beyond weight loss, patients report: cognitive improvements, reduced inflammation, and lower autoimmune markers (e.g., thyroid peroxidase antibodies in Hashimoto’s patients).
- Dependency concern is acknowledged but weighed against real quality-of-life improvements; the “win the race first, then train for the next race” philosophy.
BPC-157 (Body Protection Compound 157)
- A gut-derived peptide that survives oral ingestion but shows stronger systemic effects when injected subcutaneously.
- Primary uses observed clinically: systemic anti-inflammation, tendon/ligament repair, post-viral recovery, GI conditions (Crohn’s, IBD, leaky gut).
- Key mechanism notes:
- Stimulates fibroblast migration for connective tissue repair.
- Upregulates growth hormone receptors, making GH secretagogues more effective when stacked together.
- Works systemically—injecting near the abdomen benefits distant injury sites (e.g., elbow, Achilles).
- Protocol used clinically: 500–5,000 mcg/day, 5 days on / 2 days off.
- Also used IV as a “spark” to initiate anti-inflammatory cascades, followed by subcutaneous dosing for sustained effect.
- FDA Status: Placed on the Category 2 “no compounding” list in October 2023; recently removed from legitimate compounding channels.
Substitute: Pentadeca Arginate (PDA)
- Same core molecular structure as BPC-157; one amino acid substitution (acetate → arginate).
- Early clinical observations suggest comparable anti-inflammatory effects.
- Starting protocol: 500 mcg subcutaneous injection, 5 days on / 2 days off.
- No notable side effects observed so far.
Growth Hormone Secretagogues (GHS)
These peptides stimulate the pituitary gland to release endogenous growth hormone (GH), which then travels to the liver to produce IGF-1, promoting growth, healing, and recovery.
| Peptide | Mechanism / Flavor | Notes |
|---|---|---|
| Ipamorelin | Most receptor-specific; cleanest profile | 100 mcg max; lean-out, better sleep, no appetite spike |
| GHRP-6 | Binds GH receptor + prolactin + ACTH | Increases appetite/cortisol; best for mass gain |
| Tesamorelin | GHRH analog | Targets visceral fat; FDA-approved for HIV lipodystrophy; may work better in females |
| Sermorelin | GHRH analog | Similar to tesamorelin; may affect PSA and REM sleep in some individuals |
| CJC-1295 | Extends GH/GHRH action in bloodstream | Recently re-approved by FDA after brief ban |
| Epitalon | — | Recently re-approved by FDA |
| Thymosin Beta Alpha | Anti-inflammatory / tissue repair | Recently re-approved by FDA |
General GHS Protocol:
- Inject subcutaneously at bedtime
- No carbohydrates within ~45 minutes of injection (insulin blunts GH release)
- 5 days on / 2 days off (mirrors traditional GH dosing cycles)
- Rationale for weekend break: prevents receptor desensitization and maintains potency
Sleep timing note: The largest natural GH pulse occurs roughly 10 PM–2 AM; nighttime dosing of GHS aligns with and amplifies this pulse.
Peptide Stacking Example
Fat loss / body recomposition stack (pre-ban):
- BPC-157 → upregulates GH receptors
- Ipamorelin → subcutaneous fat reduction
- Tesamorelin → visceral fat reduction
Combined effects reported: lean muscle gain, improved sleep, better skin, faster recovery, cognitive improvements—all in one subcutaneous injection per night via compounded formulation.
Post-ban substitution: Replace BPC-157 with Pentadeca Arginate in the stack.
Testosterone & Related Hormones
- Testosterone is appropriate for testosterone replacement therapy in men with documented hypogonadism and in women; use should be supervised by a physician.
- Fertility risk: Exogenous testosterone suppresses spermatogenesis; young men using it unsupervised face risk of zero sperm count. Recovery requires agents like clomiphene, HCG, or specific peptides.
