Simple Process

How Shark Tides Works

From goal to protocol in three steps. Whether you’re a first-time user or a seasoned biohacker.

01

Choose Your Goal

Browse protocols by goal: healing & injury recovery, growth hormone optimization, fat loss, anti-aging & longevity, cognitive enhancement, or sexual performance. Every goal has a curated, evidence-based protocol.

02

Read the Deep-Dive Guide

Each peptide page includes mechanism of action, clinical study summaries, exact dosing protocols, injection timing, cycle lengths, synergistic combinations, and week-by-week result timelines.

03

Source & Execute

We only reference compounds with third-party HPLC purity testing and certificates of analysis for every batch. Your protocol deserves research-grade quality.

Our Sourcing Standard

Why We Only Recommend
One Trusted Supplier

Peptide quality varies enormously between suppliers. Underdosed, contaminated, or improperly stored peptides produce zero results — or worse. We only recommend suppliers that meet our non-negotiable quality criteria because of their uncompromising commitment to purity.

  • HPLC (High-Performance Liquid Chromatography) purity testing on every batch
  • Mass spectrometry verification of molecular weight and identity
  • Certificate of Analysis (COA) publicly available for every product
  • US-based supplier with responsible sourcing and quality control
  • Lyophilized peptides with proper cold-chain shipping

Common Questions

Peptide FAQ

Everything you need to know before starting your first peptide protocol.

QWhat are peptides and are they safe?

Peptides are short-chain amino acid sequences that signal specific biological responses — healing, hormonal, metabolic, and anti-aging. Most are derived from naturally occurring proteins in the human body, which is why their side effect profiles are dramatically more favorable than pharmacological alternatives. Compounds like BPC-157, TB-500, and Ipamorelin have extensive safety data from decades of widespread use.

QHow do I choose between BPC-157 and TB-500 for healing?

BPC-157 excels at localized tissue repair — tendons, ligaments, gut lining, and neurological injuries. TB-500 works systemically, reducing whole-body inflammation and restoring flexibility in damaged connective tissue. Most experienced users combine both as the "Ultimate Healing Stack" for synergistic effects: BPC-157 at 250–500mcg 2× daily + TB-500 at 5mg 2× weekly. See our full protocol guide.

QWhat is the best peptide for fat loss and body composition?

The most effective fat loss peptide stack combines Semaglutide (14.9% average weight loss in STEP-1), Tirzepatide (up to 22.5% weight loss — the highest ever recorded), and Ipamorelin/CJC-1295 for GH-mediated lean mass preservation. Together these peptides address appetite, metabolic rate, and body composition through multiple independent mechanisms.

QWhich peptide is best for anti-aging?

For comprehensive anti-aging, the Longevity Elite Stack combines Epithalon (telomerase activation, 27–36% mortality reduction in 15-year human follow-up studies), GHK-Cu (gene expression reset, collagen synthesis, hair growth), and NAD+ (mitochondrial restoration and sirtuin activation). Epithalon is run as a 10–20 day burst protocol 1–2× per year; GHK-Cu and NAD+ are used year-round.

QHow are peptides administered?

Most peptides are injected subcutaneously using 29–31 gauge insulin syringes — a painless process that takes under 30 seconds. Reconstitution with bacteriostatic water is required for lyophilized (freeze-dried) powders. Our protocol guides include step-by-step injection instructions, reconstitution ratios, storage requirements, and dosing schedules for every peptide.

QWhere should I buy peptides?

We exclusively recommend a US-based supplier with HPLC testing, mass spectrometry analysis, and certificates of analysis for every batch — consistently ranking as the top supplier for purity, consistency, and responsible sourcing.
