- Growth Hormone Secretagogues
- GHRP-2, GHRP-6, hexarelin, ipamorelin, CJC-1295
- S2 (Peptide Hormones)
- 24–48 hours (short-acting); 28–35 days (depot forms)
- Rarely granted; requires documented treatment failure with somatropin
- Most commonly detected peptide class in competitive sport; athletes frequently miscalculate depot form persistence
- Myostatin Inhibitors
- Follistatin-344, ACE-031, SRK-015
- S2 (Growth Factors)
- No direct threshold; biomarker panel detection (elevated serum follistatin + suppressed myostatin)
- Not available. No approved therapeutic use
- Indirect detection methodology as of 2026; compliance gap for athletes unaware of biomarker testing
- GLP-1 Receptor Agonists
- Semaglutide, tirzepatide, liraglutide
- S4 (Hormone/Metabolic Modulators)
- 35–42 days (semaglutide); 28–32 days (tirzepatide)
- Available for documented obesity/diabetes with failed first-line therapies
- Newly prohibited in 2026; endurance athletes most affected; retroactive TUEs no longer granted
- Peptide Fragments with Biological Activity
- BPC-157, TB-500 (Thymosin Beta-4 fragment)
- S0 (Non-Approved Substances)
- 7–10 days (BPC-157); 14–21 days (TB-500)
- Not available. No regulatory approval
- S0 classification triggers automatic four-year sanctions; no medical defence pathway
- IGF-1 and Analogues
- IGF-1 LR3, DES(1-3) IGF-1
- 48–72 hours (IGF-1); 5–7 days (long-acting analogues)
- Rarely granted; limited to severe growth hormone insensitivity syndromes
- Detection improved significantly in 2025 with new immunoassay kits; athletes who previously evaded testing now face higher AAF risk
