Peptides Masterclass Part 2: Evidence Tiers + Purity Red Flags (No Hype)
People love peptide “stacks.” Reality loves baselines, evidence tiers, and stop rules.
Part 1(click here)
In Part 2 of the Peptides Masterclass, UltimateBiohacker10X breaks down the Evidence Ladder (Tier 1 human RCTs → Tier 2 small human/mechanistic → Tier 3 preclinical/early) and the Quality Red Flags that turn “biohacking” into expensive confusion.
We run the 5 peptide buckets people actually search:
Fat loss: GLP-1 context + AOD-9604 reality checkInjury/Recovery: BPC-157 + TB-500 (what we know vs what’s assumed)Sleep/Brain: Selank, Semax, DSIP (mechanism ≠ outcome)Longevity/Immune: TA1, MOTS-c, KPV (define longevity with metrics)Skin/Hair: GHK-Cu + topical penetration reality (physics > marketing)Rule #1 stays undefeated: foundations first. If you aren’t tracking baselines, you aren’t doing an experiment—you’re doing a vibe.
Educational only. Not medical advice. No dosing. No sourcing. Consult a qualified clinician for personalized decisions.
