Practical, math-backed articles on reconstitution, dosing protocols, and peptide research. No hype, just the numbers.
LL-37 ships as a lyophilized powder in 5 mg vials and is more fragile than the small repair peptides it gets grouped with. This guide covers the mixing steps, four concentration options, how to hit the 0.5 mg/mL concentration used in the clinical wound trials, and the handling cautions specific to a membrane-active peptide.
Melanotan 2 ships as a lyophilized powder in 10 mg vials, and the BAC water volume you choose decides whether your 250 mcg dose lands on a clean syringe mark or an awkward fraction. This guide covers the mixing steps, four concentration options, and the mole-monitoring precaution that separates this peptide from most others.
GHK-Cu is dosed two completely different ways, and the two are not interchangeable. This guide covers the topical concentration range that has human data behind it, the 1 to 2 mg subcutaneous range that does not, and the copper load that caps how long you can run either.
Epithalon is dosed in short pulsed courses, not run continuously, which makes it unlike almost every other peptide in common use. This guide covers the 5 to 10 mg range, the standard 10-day course, exact syringe units at each concentration, evening timing, and how many courses per year the research actually used.
Hexarelin is the most potent of the common GHRPs per microgram, which makes accurate reconstitution math more consequential than it is with gentler secretagogues. This guide covers vial sizing, BAC water volumes, unit conversion, and storage.
Not every peptide needs a cycle, but the ones that act on a receptor system with feedback control usually do. This guide covers which compounds require off periods, how long standard cycles run, and how to structure a restart.
Once bacteriostatic water hits the powder, the vial is on a clock. This is the operational protocol for the 28 days that follow: where the vial goes, how to log it, how many punctures it can take, and how to judge a vial that spent a night on the counter.
GHRP-6 ships as a lyophilized powder in 5 mg and 10 mg vials and is dosed at 100 to 300 mcg, so the BAC water volume you pick decides whether your dose lands on a readable syringe mark. This guide covers the concentration math, the mixing sequence, storage limits, and how the strong hunger response changes injection timing.
NAD+ and NMN target the same pathway from opposite ends: one is the finished coenzyme delivered by injection, the other is an oral precursor your cells convert in a single enzymatic step. This guide compares bioavailability, dosing, side effects, and cost.
Half-life is the single number that explains why some peptides are injected once a week and others three times a day. This guide covers the math, a reference table for common compounds, and how to translate half-life into a real dosing schedule.
Tirzepatide and retatrutide share two of the same three receptor targets, so this is the cleanest comparison in the metabolic peptide class: the only mechanistic variable is the glucagon arm. Here is how that single difference changes dosing, titration, side effects, and what the trial data supports.
GHRP-2 ships as a lyophilized powder in 5 mg and 10 mg vials, and doses land in the 100 to 300 mcg range, so small syringe volumes are unavoidable. This guide covers the BAC water volumes that keep the math clean, the mixing sequence, and how long the vial stays good.
Retatrutide is a triple GLP-1 / GIP / glucagon agonist dosed in whole milligrams; semaglutide is a GLP-1 mono-agonist dosed in fractions of a milligram. That 5-fold dose gap changes your reconstitution math, your syringe choice, and what the trial data can tell you.
Almost every research peptide is given subcutaneously into one of four fat-rich sites. This guide covers the anatomy of each site, needle length and angle, and a rotation system that keeps absorption consistent over months of use.
BPC-157 and TB-500 are the two most commonly used repair peptides, but they work through different pathways and run on completely different dosing schedules. This guide compares mechanism, dose, frequency, and how people stack them.
PT-141 is dosed as needed rather than daily, which makes starting dose and timing the two variables that matter most. This guide covers the 1 to 2 mg range, exact syringe units at common concentrations, the 45 to 60 minute onset window, and the frequency ceiling.
Sermorelin works through your own pituitary, which means dose size matters less than timing and fasting state. This guide covers the 200-500 mcg range, exact syringe units at standard concentrations, cycling, and how to verify results with IGF-1 labs.
Storage is the single biggest variable in whether a peptide vial still works on day 25. This guide covers exact temperature ranges, realistic shelf life for lyophilized and reconstituted vials, and the handling mistakes that quietly destroy potency.
The ipamorelin and CJC-1295 combination is the most widely used growth hormone secretagogue stack. This guide covers why the two peptides synergize, exact reconstitution volumes, unit math, and the timing rules that determine whether the protocol works at all.
NAD+ must be reconstituted carefully to preserve potency and avoid degradation. This guide covers the right BAC water volume, injection routes, flushing technique, and how to use PeptiTools to calculate every draw.
TB-500 is a synthetic fragment of Thymosin Beta-4, studied for its roles in tissue repair, angiogenesis, and inflammation modulation. This guide covers how to reconstitute it, choose the right concentration, and calculate your draw amount using the PeptiTools calculator.
Insulin syringes use unit markings, not milliliters. Understanding the difference between units and mL is essential for accurate peptide dosing. This guide explains syringe scales, how to find your draw line, and how PeptiTools converts your dose to a unit number automatically.
Retatrutide is a triple receptor agonist targeting GLP-1, GIP, and glucagon receptors simultaneously. Phase 2 trial data showed up to 24.2% weight loss at 48 weeks. This guide covers reconstitution, concentration selection, and the titration schedule used in clinical research.
Semaglutide and tirzepatide are both injectable GLP-1 receptor agonists, but they differ in mechanism, dose range, and reconstitution strategy. This side-by-side comparison covers the math, the titration schedules, and what the clinical trial data shows.
BPC-157 is a research peptide derived from a sequence in human gastric juice, studied for its effects on tissue repair. This guide covers how to reconstitute it, choose a concentration, and calculate your draw amount with the PeptiTools calculator.
Tirzepatide is a dual GLP-1 and GIP receptor agonist requiring careful reconstitution with bacteriostatic water. This guide covers the exact steps, concentration math, and how to use the PeptiTools calculator to find your draw amount.
Reconstituting semaglutide correctly is critical for safe, effective dosing. This guide walks through every step, from choosing the right BAC water volume to calculating your draw amount.
