Aesthetics Peptides
Skin, collagen, hair, and pigmentation compounds, and what the dermatology literature shows.
Aesthetic peptides have an advantage over the rest of the library: skin is easy to biopsy and easy to photograph, so the endpoints are measurable and the studies are shorter. GHK-Cu has decades of dermatology literature on collagen synthesis and wound repair. The melanocortin compounds are a different story, one is an approved drug for a rare photosensitivity disorder, the other is an unapproved analog with real safety signals. The distinction matters and the grades reflect it.
GLOW Blend
B-gradeA copper-peptide-forward single-vial blend pairing GHK-Cu's skin remodeling with BPC-157 and TB-500's tissue-repair support.
Melanotan I (Afamelanotide)
B-gradeThe only melanotan with FDA approval, cleared as Scenesse in 2019 for a rare disorder where sunlight causes severe skin pain, not for general tanning.
Melanotan II
B-gradeA synthetic melanocortin agonist used to darken skin (tanning), with libido effects and notable safety cautions.
GHK-Cu
C-gradeA copper-binding tripeptide used for skin remodeling, collagen synthesis, hair growth, and wound healing.
AHK-Cu (Copper Tripeptide-3)
D-gradeA copper-binding tripeptide related to GHK-Cu, with research skewed toward hair-follicle and scalp effects rather than general skin remodeling.
SNAP-8
D-gradeThe 'topical Botox' marketing peptide, a lab-dish mechanism with no controlled human trial proving the cream actually smooths wrinkles.

Aesthetics peptide questions
How many aesthetics peptides are there?
This library covers 6 aesthetics compounds, each graded from S (regulatory approval) to F (no usable evidence).
Which aesthetics peptide has the strongest evidence?
GLOW Blend carries the highest research grade in this category at B. A copper-peptide-forward single-vial blend pairing GHK-Cu's skin remodeling with BPC-157 and TB-500's tissue-repair support.
What does the research grade mean?
The grade describes how well a compound has been measured in humans, not how well it works. S means regulatory approval; D means animal data only. Popularity and anecdote do not affect it.
