peptide

Mechanism of Action

Long-acting IGF-1 variant that remains active much longer than natural IGF-1, creating pronounced anabolic effects.

Benefits

  • Powerful anabolic signaling
  • Promotes muscle hyperplasia (new cells)
  • Enhances hypertrophy (cell growth)
  • Synergistic with HGH secretagogues
  • Accelerated recovery

Side Effects

  • Potential insulin resistance
  • Hypoglycemia risk
  • Water retention
  • Nerve pain (carpal tunnel)
  • Requires careful dosing

5-Amino-1MQ
A small molecule peptide that selectively inhibits NNMT (Nicotinamide N-methyltransferase), an enzyme linked to fat storage, obesity, and metabolic dysfunction. By blocking NNMT, it increases NAD+ levels and activates the sirtuin longevity pathway.
peptide

Mechanism of Action

Inhibits NNMT enzyme which normally depletes NAD+ and promotes fat storage. By blocking NNMT, cellular NAD+ levels increase, activating SIRT1 longevity genes, boosting cellular energy metabolism, and shrinking fat cells (adipocytes). Also increases SAM (S-adenosylmethionine) availability for DNA methylation.

Benefits

  • Potent fat loss through NNMT inhibition and adipocyte shrinkage
  • Increases cellular NAD+ levels naturally (synergistic with NAD+ supplementation)
  • Activates SIRT1 longevity pathway
  • Boosts basal metabolic rate and energy expenditure
  • May reverse diet-induced obesity
  • Improves cellular energy metabolism
  • Supports healthy DNA methylation patterns
  • Non-hormonal — suitable for both males and females

Side Effects

  • Limited human clinical data — primarily animal studies
  • Possible mild GI discomfort
  • Headache reported in some users
  • Unknown long-term safety profile
  • Expensive compared to other fat loss compounds

Epitalon (Epithalon)
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) that directly activates telomerase, the enzyme responsible for rebuilding telomeres. It is the only known compound that directly targets the TERT gene for telomere lengthening.
peptide

Mechanism of Action

Stimulates the production of telomerase in somatic cells, which rebuilds and lengthens telomeres at the ends of chromosomes. This effectively reverses one of the primary mechanisms of cellular aging, allowing cells to continue dividing beyond their normal limit.

Benefits

  • Directly activates telomerase enzyme via TERT gene stimulation
  • Lengthens telomeres — reverses cellular aging clock
  • Improves sleep quality and circadian rhythm regulation
  • Enhances melatonin production in the pineal gland
  • Antioxidant properties — reduces lipid oxidation
  • May improve immune function and T-cell activity
  • Potential anti-cancer properties through normalized cell function
  • Shown to extend lifespan in animal studies by 13-30%

Side Effects

  • Generally well-tolerated with minimal reported side effects
  • Mild injection site irritation
  • Possible drowsiness due to melatonin regulation
  • Limited long-term human safety data
  • Theoretical concern about promoting cancer cell telomere growth (unproven)

  • Improved skin quality and anti-aging
  • Enhanced recovery and healing
  • Better sleep quality
  • Increased muscle mass over time
  • Joint and connective tissue repair
