02 / Mechanism

How it is thought to work

Short-acting IGF-1 variant used near the target muscle

Mechanisms seen in cells or animals do not always happen the same way in people.

03 / Potential benefits

What people use it for

Local muscle growth

Animal or no human data

No meaningful human data. Effects and safety in people are unknown, which is not the same as safe.

Listed uses are what people use it for, not proven outcomes.

04 / Known risks

Side effects and risks

Low blood sugar, theoretical cancer-growth risk

Risk level 8 of 10

High risk score: serious harms are documented or plausible, and there is little data to rule them out.

Unknown long-term effects count as a risk, not as a clean record.

05 / Regulatory

07 / Notes and sources

Notes and sources

  • Growth-factor peptides carry a theoretical risk of feeding existing cancers.
  • Animal only means effects and safety in humans are unknown, not that they are proven safe.
  • Products sold online as research peptides are unregulated. Tests of such products often find wrong amounts, impurities or a different compound.
  • Anyone using compounds like this regularly should have medical supervision and bloodwork (for example IGF-1, glucose and HbA1c, hormones, lipids).
  • Source: Peptide Reference Table, an editorial review of published research up to mid-2026. Scores are 1 to 10 editorial estimates, not measured values. Regulatory and WADA status change over time.
