Peptide Calculators

BPC-157

200-500 mcg · 2x daily (morning and evening)

15-amino acid peptide derived from human gastric juice. Studied for tendon, ligament, muscle, and gut repair.

TB-500

2000-5000 mcg · 2x weekly

Synthetic fragment of thymosin beta-4. Studied for tissue repair, wound healing, and inflammation reduction.

Semaglutide

250-2500 mcg · 1x weekly

GLP-1 receptor agonist. Reduces appetite and slows gastric emptying. Dosed weekly with gradual titration up from 0.25mg.

Tirzepatide

2500-15000 mcg · 1x weekly

Dual GIP/GLP-1 receptor agonist. Dosed weekly with titration starting at 2.5mg. Stronger appetite suppression than semaglutide in trials.

AOD-9604

250-500 mcg · 1x daily, morning on empty stomach

Modified HGH fragment (amino acids 177-191). Targets fat metabolism without the growth-promoting effects of full HGH.

MOTS-c

5000-10000 mcg · 3-5x weekly

Mitochondria-derived peptide encoded in mtDNA. Studied for metabolic regulation, exercise mimicry, and insulin sensitivity.

CJC-1295 / Ipamorelin

200-300 mcg · 1x daily before bed

GHRH + secretagogue combo. Stimulates pulsatile growth hormone release. Studied for GH output, sleep quality, and recovery.

Sermorelin

200-500 mcg · 1x daily before bed

GHRH analog containing the first 29 amino acids of native GHRH. Stimulates natural GH production. Very short half-life (~12 min).

GHK-Cu

200-600 mcg · 1x daily

Naturally occurring copper tripeptide. Studied for skin remodeling, wound healing, and hair growth.

PT-141

500-2000 mcg · As needed, 30-45 min before

Melanocortin receptor agonist studied for sexual dysfunction. Acts on the CNS, not the vascular system. Used as needed.

DSIP

100-300 mcg · 1x daily, 30 min before bed

Neuropeptide studied for promoting delta-wave sleep. May normalize sleep architecture and speed up sleep onset.

Selank

250-750 mcg · 1-2x daily, intranasal or subcutaneous

Synthetic tuftsin analog. Studied for anxiolytic and nootropic effects. Developed at the Institute of Molecular Genetics (Russian Academy of Sciences).

Semax

200-600 mcg · 1-2x daily, intranasal or subcutaneous

Synthetic ACTH(4-10) analog. Studied for cognitive enhancement, neuroprotection, and BDNF upregulation. Developed in Russia.
