Don't see a peptide you're researching? Let us know and we'll add it to the database.
The app includes an interactive calculator that handles the math automatically. Here is the underlying methodology.
Vial Strength (mg) ÷ Desired Dose (mg) = Number of DosesExample: 10 mg vial ÷ 1 mg dose = 10 doses
Total BAC Water Added (ml) ÷ Number of Doses = Volume per Dose (ml)Example: 2 ml water ÷ 10 doses = 0.2 ml per dose
Volume per Dose (ml) × 100 = Units on a 1 ml Insulin SyringeExample: 0.2 ml × 100 = 20 units
Gold standard for most peptides. Inject into fatty tissue of the abdomen, thigh, or deltoid. Rotate sites to prevent lipodystrophy.
Used for compounds like Testosterone Cypionate. Slightly faster absorption than subcutaneous.
Preferred route for brain-targeting peptides (Semax, Selank). Bypasses the blood-brain barrier via the olfactory nerve pathway — CNS bioavailability is high despite low systemic absorption. Requires a nasal atomizer. See the Nasal Spray Guide below.
Standard oral is poor due to gastric breakdown. Sublingual can reach up to 36% for select formulations.
Used for GHK-Cu and collagen peptides in skincare. Penetration depends on molecular weight and formulation.
Semax and Selank are the two peptides on this platform that work best as nasal sprays. They travel directly to the brain through the olfactory nerve — no injection needed.
Add bacteriostatic water to the lyophilized powder. For Selank (5 mg vial): add 2.5 ml BAC water → 2,000 mcg/ml. For Semax (30 mg vial): add 3 ml BAC water → 10,000 mcg/ml.
Use a sterile nasal atomizer with a Luer-lock tip. Draw the reconstituted solution into a 1 ml syringe and attach the atomizer. Each pump delivers ~100 mcg (Selank) or ~200–300 mcg (Semax) depending on the atomizer.
Tilt head slightly forward. Insert the atomizer tip just inside one nostril, aim toward the outer wall (not straight up). Press the plunger firmly and quickly. Sniff gently. Alternate nostrils each dose to reduce irritation.
Store reconstituted solution in the refrigerator (2–8°C). Use within 30 days. Keep the atomizer capped between uses. Do not freeze.
Note: Oral administration is not effective for Semax or Selank — digestive enzymes break down the peptide chains before they can be absorbed. Nasal or subcutaneous injection are the only effective routes.
A full-stack, PWA-enabled platform designed to guide researchers from goal identification to optimized peptide protocols.
A multi-step onboarding quiz identifies user goals, experience level, and budget — then maps responses to the optimal peptide protocol using a weighted scoring engine.
55+ detailed peptide profiles covering mechanism of action, clinical research summaries, side effect profiles, dosing protocols, and administration routes.
An interactive tool that calculates BAC water volume, dose per injection, and syringe unit conversions for any vial strength and desired dose combination.
A calendar-based protocol manager that tracks injection days, cycle lengths, and mandatory rest periods — with push notifications for dosing reminders.
Evidence-based supplement stacks, dietary protocols, and exercise recommendations tailored to each peptide to maximize therapeutic outcomes.
PWA push notifications deliver context-aware dosing reminders — fasted morning injection, pre-bedtime dose, cycle break alerts — to keep users on protocol.
Developed in Soviet-era neuroscience programs and refined over decades of clinical use, this three-peptide cognitive stack remains one of the most studied and respected nootropic protocols in peptide research.
Cognitive enhancement · Neuroprotection · Anxiety reduction · BDNF upregulation
ACTH(4-7)PGP Analogue
Upregulates BDNF and NGF, enhancing memory consolidation, focus, and executive function. The stimulating leg of the trio — best taken in the morning.
Tuftsin Analogue
Modulates GABA-A and serotonin receptors to reduce anxiety without sedation. Balances Semax's stimulating effects and promotes calm, focused cognition.
Porcine Brain Peptide Complex
A complex of neuropeptides and amino acids that mimics endogenous neurotrophic factors. Promotes neuroplasticity, synaptic repair, and long-term cognitive resilience.
Typical Cycle
4–8 weeks on, 2–4 weeks off
Administration Timing
Semax + Selank: morning. Cerebrolysin: 10-day course cycles.
Best For

For research purposes only. Open each peptide profile for full dosing protocols, safety information, and reconstitution instructions.
A three-peptide protocol targeting fat metabolism through complementary mechanisms — GLP-1 appetite suppression, direct lipolysis, and visceral fat reduction — for a comprehensive body composition approach.
Appetite suppression · Lipolysis · Visceral fat reduction · GH secretion
GLP-1 Receptor Agonist
Mimics GLP-1 to reduce appetite, slow gastric emptying, and improve insulin sensitivity. The anchor of the stack — controls caloric intake while the other peptides drive fat mobilization.
hGH Fragment 177-191
The fat-burning fragment of human growth hormone. Directly stimulates lipolysis and inhibits lipogenesis without the blood sugar or IGF-1 effects of full HGH. Targets stubborn adipose tissue.
GHRH(1-44) Analogue
FDA-approved for HIV-associated lipodystrophy. Stimulates natural GH release to specifically reduce visceral adipose tissue — the metabolically active fat around organs that is hardest to lose.
Typical Cycle
12–16 weeks with gradual dose escalation
Administration Timing
Semaglutide: once weekly. AOD-9604 + Tesamorelin: daily, fasted morning.
Best For
Stubborn fat loss, visceral adiposity, metabolic syndrome, body recomposition
For research purposes only. Semaglutide requires a prescription — consult a licensed provider via Glow Natural Wellness. Open each peptide profile for full dosing protocols and safety information.
The most researched tissue repair and regeneration combination — used by athletes, post-surgical patients, and anyone recovering from injury or overtraining.
Body Protection Compound — accelerates healing of tendons, ligaments, muscle, and gut lining by upregulating growth factor receptors and promoting angiogenesis.
Thymosin Beta-4 analogue — promotes systemic tissue repair, reduces inflammation, improves flexibility, and accelerates recovery from muscle tears and chronic injuries.
Copper peptide — resets gene expression toward a youthful state, stimulates collagen synthesis, reduces oxidative stress, and enhances wound healing and skin regeneration.
Cycle Length
8–12 weeks, repeat as needed
BPC-157 Timing
Daily SubQ near injury site, or oral for gut
TB-500 Timing
2x/week loading for 4 weeks, then 1x/week
GHK-Cu Timing
Daily SubQ or topical, morning or evening
For research purposes only. Open each peptide profile for full dosing protocols, reconstitution instructions, and safety information.
A three-peptide protocol targeting libido, arousal, and hormonal optimization — combining a central melanocortin activator with natural gonadotropin support for comprehensive sexual health and hormone balance.
Libido activation · Arousal · Hormonal optimization · LH/FSH support
Bremelanotide, MC3R/MC4R Agonist
Activates melanocortin receptors in the hypothalamus to directly stimulate sexual arousal and desire — independent of hormonal levels. Works in both men and women.
KP-10, KISS1 Receptor Agonist
Stimulates GnRH release from the hypothalamus, triggering a downstream cascade of LH and FSH secretion. Naturally elevates testosterone and estrogen for sustained hormonal support.
GnRH Analogue, Gonadotropin-Releasing Hormone
A synthetic GnRH analogue that maintains hypothalamic-pituitary-gonadal axis signaling. Commonly used alongside TRT to preserve natural testosterone production and testicular function.
Typical Use
PT-141: as-needed (1–2x/week max). Kisspeptin-10 + Gonadorelin: 2–3x/week ongoing.
Administration Timing
PT-141: 45–60 min before activity. Kisspeptin-10 + Gonadorelin: morning or evening, consistent timing.
