Reference

Editorial diagram on a soft off-white surface: two stylised receptor shapes labelled 'GHRH receptor' and 'GHS-R1a / Ghrelin receptor' sit side by side on a stylised pituitary cell, with two distinct curved arrows reaching them - one labelled 'Mod GRF / Sermorelin / CJC-1295 / Tesamorelin' arriving at the GHRH receptor, the other labelled 'Ipamorelin / GHRP-2 / Hexarelin' arriving at the GHS-R1a receptor. A small annotation between them: 'Stack across receptors, not within.' Clean medical-illustration style, restrained palette of slate-blue, sage and warm rust on bone, sans-serif typography, generous negative space at the top for a headline.

GHRH vs GHRP: Decoder

Two different receptors, two different mechanisms, often paired. Quick decoder for which catalogue compounds are GHRH analogues vs GHRPs vs neither, with the synergy logic and the don't-stack rules in one screen.

Editorial flat-lay infographic on a soft off-white surface: an insulin syringe lying horizontal with unit-mark gradients clearly visible, a small ml-marked measuring cylinder, and a labelled stack of three small vials marked 'mcg', 'mg', 'IU' in clean sans-serif type. Thin underlying grid lines suggest reference-card aesthetic. No faces, no clinical setting, no skin or tissue depicted. Magazine-style infographic, restrained palette of bone, slate-blue and warm rust, generous negative space at the top for a headline.

Syringe Unit Conversions

mcg / mg / IU and how insulin-syringe units map to mL. Quick lookup for the conversions that come up at the bench, with the HGH IU-vs-mg gotcha called out separately.

Editorial overhead infographic on a soft off-white surface: a 3x3 grid of small abstract glyphs each representing a peptide class - chain, copper ring, pulse wave, thymus silhouette, GLP-1 receptor curve, IGF spiral, growth-factor branch, melanocyte dot pattern, mitochondrial coil. Each glyph in muted distinct hues against bone background, generous spacing, no labels, no faces, magazine-grade reference style, restrained palette of slate-blue, sage, warm rust and copper, generous negative space at the top for a headline.

Peptide Class Lookup

The nine canonical peptide classes used across this catalogue, with representative compounds linked to their pages and the application contexts where each class shows up.

Cheat sheet

Editorial overhead still life on a soft off-white surface: three small unbranded blood-collection tubes laid horizontally in a row, each tube cap a different muted hue (slate-blue, sage, warm rust). A folded paper request form is visible at the edge of frame as a textured background element. No faces, no clinical setting, no needles depicted. Magazine-grade reference style, restrained palette of bone, slate-blue and warm rust, sans-serif typography, generous negative space at the top for a headline.

Bloodwork Panel Cheat Sheet

Per-peptide-class bloodwork panel and timing - the standard ask for the lab, with the markers that actually move and the cadence that catches drift.

Editorial overhead still life on a soft off-white surface: a small unbranded glass vial sitting on a thin slice of cold-pack gel, with a faint frost effect, and a thin paper temperature-strip indicator just visible at the edge of frame. No faces, no clinical setting, no needles depicted. Magazine-grade reference style, restrained palette of bone, slate-blue and pale ice-blue, sans-serif typography, generous negative space at the top for a headline.

Cold-Chain Quick Reference

Storage temps, room-temp tolerance, freezing rules, and travel cadences for the catalogue’s peptide classes - lyophilised vs reconstituted, by class.

Editorial overhead anatomical diagram on a soft off-white background, magazine style. Abstract front-facing torso silhouette with four labelled SC zones: abdomen, outer thighs, upper outer hips, and back of upper arms - each shaded in a distinct muted hue (slate-blue, sage, warm rust, dusty olive). Each zone subdivided into a small dotted-grid showing seven numbered cells. A 14-day calendar strip runs across the top, with each day annotated by zone-cell pair. Restrained palette, clean medical-illustration style, no faces, no needles depicted, generous white space, sans-serif typography.

Injection Rotation Grid

Two-week SC site rotation grids for daily, BID, and weekly injection cadences. Zone map, cell numbering, and the 2 cm intra-zone spacing that keeps tissue healthy.

Editorial flat-lay illustration on a soft off-white surface: a small unbranded glass vial, an insulin syringe with the barrel laid horizontal, and a small ml-marked vial of bacteriostatic water, all spaced cleanly with a thin underlying grid pattern suggesting math reference. No faces, no clinical setting, no needles depicted in tissue. Magazine-style infographic, restrained palette of bone, slate-blue and warm rust, generous negative space at the top for a headline.

Reconstitution Cheat Sheet

One-screen reconstitution math: vial size, BAC water volume, resulting concentration, and the insulin-syringe unit mark for the dose you actually want.

Protocol

Editorial overhead still life on a soft off-white surface: a small unbranded glass vial sitting next to a folded swatch of warm sand-coloured fabric and a thin cotton sun-visor, with a soft circular sun-shape illustration above as a textured background element. No faces, no clinical setting, no needles depicted. Magazine-grade reference style, restrained palette of bone, warm rust and sand-tan, sans-serif typography, generous negative space at the top for a headline.

Melanotan II Loading Protocol

The loading + maintenance MT-II protocol that mitigates nausea on the way up and uses weekly maintenance once pigment is set. Dose ramp, UV pairing, antihistamine timing, and the dermatology baseline.

Editorial overhead still life on a soft off-white surface: a small unbranded glass vial sitting on a folded cotton napkin next to a small analog alarm clock showing 11pm. A faint moon-shape illustration above as a soft background element. No faces, no clinical setting, no needles depicted. Magazine-grade reference style, restrained palette of bone, slate-blue and warm rust, sans-serif typography, generous negative space at the top for a headline.

Pre-Bed GH-Secretagogue Protocol

The most common GH-axis entry point: Mod GRF 1-29 + Ipamorelin pre-bed, on an empty stomach, with the dose, timing, fasting window, and what to expect from bloodwork.

Editorial illustration on a soft off-white surface: a clean horizontal rising staircase representing dose escalation with five labeled steps (0.25 / 0.5 / 1.0 / 1.7 / 2.4 mg), then a long flat plateau line, then a small downward step labeled 'maintenance taper'. Each step subtly annotated with the typical 4-week interval. Magazine-grade infographic style, restrained palette of slate-blue, sage and warm rust on bone, sans-serif typography, generous white space, no chart axes.

GLP-1 Titration Schedule

Step-up cadence for semaglutide, tirzepatide and retatrutide, including the standard 4-week climb, the slower 6–8-week variant, split-dosing, hold rules, and the maintenance taper.

Quick lookup

Editorial overhead illustration on a soft off-white surface: two small unbranded glass vials laid side by side with a thin red caution stripe drawn between them in dotted ink, plus a third vial set apart at the edge of frame as a textured background element. No faces, no clinical setting, no needles depicted. Magazine-grade reference style, restrained palette of bone, slate-blue and warm rust, sans-serif typography, generous negative space at the top for a headline.

Stacking Safety Quick Reference

Known peptide-and-peptide and peptide-and-drug conflicts that change the protocol - IGF-1 + insulin, MT-II + PDE5, GLP-1 + oral absorption, corticosteroids + Tα1, and the AAS overlap rules.

Editorial overhead illustration on a soft off-white surface: a clean grid of small abstract pill / vial / capsule glyphs arranged in three rows, each row tinted in a distinct muted hue (slate-blue, warm rust, sage). A small key in the corner pairs each colour with a category label suggested by tone alone. No faces, no clinical setting, no needles depicted. Magazine-grade reference style, restrained palette, sans-serif typography, generous negative space at the top for a headline.
