Reads that cut across compounds: what has been studied for each goal, head-to-head comparisons, and the practical side of research peptides in the Philippines.

Peptides by goal

16

Best Peptides for Anti-Aging

SS-31, NAD+, MOTS-c, epitalon and SLU-PP-332 ranked by evidence quality for longevity research, from FDA-approved to mice-only, not by popularity.

Best Peptides for Brain Function

Cerebrolysin, Semax, Selank, Pinealon and Dihexa ranked by trial evidence, from a Philippine-registered drug to a peptide with zero human data.

Best Peptides for Energy

SS-31, NAD+, MOTS-c, 5-Amino-1MQ and SLU-PP-332 are sold for energy and endurance. What was actually measured in people, separated from mouse running data.

Best Peptides for Gut Health

BPC-157, KPV and TB-500 ranked by the strength of their rat and mouse gut-healing evidence. No human trial exists for any of them yet.

Best Peptides for Hair Growth

GHK-Cu is the only peptide in this library with any published link to hair growth, and even that is a review mention of animal and cell work, not a human trial.

Best Peptides for Inflammation

KPV, thymosin alpha-1, ARA-290, BPC-157 and LL-37 get sold for inflammation. What is approved, what is a small human trial, and what is mouse or cell work only.

Best Peptides for Injury Healing

BPC-157, TB-500 and injectable GHK-Cu are sold for tendon injuries. What the rat and cell studies behind them found, ranked honestly by evidence strength.

Best Peptides for Joint Pain

Retatrutide's knee osteoarthritis trial, BPC-157, TB-500, AOD-9604's rabbit OA data and GHK-Cu ranked by evidence strength for joint pain, not popularity.

Best Peptides for Libido

PT-141 is FDA-approved for low desire in premenopausal women. Kisspeptin and melanotan-2 have thinner or riskier human data. Ranked by evidence, not hype.

Best Peptides for Men

GLP-1 medicines, tesamorelin, hCG and kisspeptin are what men actually search for. What the trials measured for body composition, testosterone and libido.

Best Peptides for Menopause

No peptide is approved for menopause symptoms. What has been studied around midlife weight gain and skin, ranked by evidence, and where hormone therapy fits.

Best Peptides for Muscle Growth and Fat Loss

Approved GLP-1 medicines, GH-axis peptides and myostatin blockers ranked by trial evidence for fat loss and muscle, with the lean-mass caveat explained.

Best Peptides for Skin

Argireline, GHK-Cu and SNAP-8 are sold for skin quality and expression lines. What their human trials, or lack of them, actually found, ranked by evidence.

Best Peptides for Sleep

DSIP, MK-677 and epitalon are all sold for sleep. What the small 1980s to 1990s trials, and thinner data behind the others, actually found, ranked by evidence.

Best Peptides for Testosterone

Only the HPG axis raises testosterone: hCG, kisspeptin and gonadorelin. What their trials measured, why GH peptides don't touch it, and PH prescribing rules.

Best Peptides for Women

Semaglutide, tirzepatide, PT-141 and GHK-Cu are the compounds most searched for women's goals. What their human trials found, ranked by evidence.

Comparisons

BPC-157 vs TB-500: What the Research Actually Separates

BPC-157 and TB-500 are sold as a pair but are unrelated molecules with different evidence. The rat data, the one direct comparison, and what is untested.

CagriSema vs Tirzepatide: The REDEFINE 4 Head-to-Head

CagriSema pairs an amylin analogue with semaglutide; tirzepatide hits GIP and GLP-1 in one peptide. Their pivotal trials and the REDEFINE 4 head-to-head.

CJC-1295 With DAC vs Without DAC: One Backbone, Two Drugs

The DAC linker turns a short GHRH pulse into a signal lasting days. Which version the 2006 human trials tested, and what the no-DAC peptide is missing.

GHRP-2 vs GHRP-6: The Original Hexapeptides Compared

GHRP-6 was the first GH-releasing hexapeptide; GHRP-2 is its more potent successor and a diagnostic drug in Japan. Human data, hunger, cortisol and WADA status.

HGH vs GH Peptides: Hormone Replacement vs Pituitary Signalling

Somatropin (HGH) is a prescription hormone given directly. GH secretagogue peptides ask the pituitary to release its own. How the two categories differ.

Ipamorelin vs MK-677: Injected Peptide vs Oral Ghrelin Mimetic

Ipamorelin and MK-677 share the ghrelin receptor, but only one is a peptide and only one has a two-year trial. What ipamorelin's record covers.

Ipamorelin vs Sermorelin: Two Routes to the Same Hormone

Ipamorelin acts on the ghrelin receptor, sermorelin on the GHRH receptor. What each one's human studies measured, why they are paired, and their status.

Orforglipron vs Oral Semaglutide: Two GLP-1 Pills, One Direct Trial

Orforglipron is a small molecule; Rybelsus is a peptide with an absorption enhancer. The ACHIEVE-3 head-to-head, the fasting rules, and PH status.

Semaglutide vs Liraglutide: The Head-to-Head Trial and What Changed

The two GLP-1 peptides sold in Philippine pharmacies. What the STEP 8 head-to-head found, how their outcome trials differ, and prescription status.

Semax vs Selank: Comparing the Two Russian Nasal Peptides

Semax and Selank are Russian nasal peptides from the same research network, one for stroke and cognition, the other for anxiety. What the evidence shows.

Tesamorelin vs Sermorelin: Two GHRH Analogues Compared

Tesamorelin and sermorelin both come from growth hormone-releasing hormone, but only one is still an approved medicine. How their trials and status differ.
