SARMs vs Peptides: Complete Comparison

The worlds of SARMs (Selective Androgen Receptor Modulators) and peptides often overlap in discussions about muscle building, fat loss, and performance enhancement. Both are popular alternatives to traditional anabolic steroids, but they work through completely different mechanisms and offer distinct advantages and disadvantages.

HGH 191AA: The Complete Guide to Somatropin

HGH 191AA (Human Growth Hormone 191 Amino Acid) is the bioidentical form of somatropin, the growth hormone naturally produced by your pituitary gland. Unlike older 192AA formulations that contained an extra methionine amino acid, HGH 191AA is structurally identical to what your body produces, making it the gold standard in growth hormone research and therapy.
