Peptides are short chains of amino acids that signal specific processes in the body — tissue repair, growth hormone release, or inflammation control. They are prescription compounds and require a doctor's supervision.

Which peptides are used for muscle gain?

Growth hormone secretagogues like CJC-1295 and Ipamorelin are the most common for lean mass support. BPC-157 and TB-500 are used for soft-tissue recovery so you can train harder more often.

Many peptides are legal with a prescription from a licensed physician. They are banned by WADA for tested athletes. STAKD does not sell or prescribe peptides — the protocol tracker is for users following a doctor-assigned plan.

What is BPC-157 used for?

BPC-157 (Body Protection Compound) is most often used for tendon, ligament, and gut healing. Athletes use it during nagging soft-tissue injuries on a doctor's plan.

Do peptides replace training and nutrition?

No. Peptides amplify what training and nutrition already build. Without progressive overload, adequate protein, and sleep, no protocol does much.

Peptide Protocols for Muscle Gain

Educational overview of the peptide compounds most commonly prescribed for muscle gain and recovery. This is not medical advice — peptides are prescription compounds and require a licensed physician's supervision.

STAKD does not prescribe or sell peptides. The Protocol tracker exists so users with a doctor-assigned stack can log doses, cycles, and outcomes alongside training and nutrition.

Common compounds

A high-level comparison. Dosage, timing, and cycling are individual and must come from your physician.

Compound	Primary goal	How it works
CJC-1295 + Ipamorelin	Lean muscle / recovery	Growth hormone secretagogue stack — pulses natural GH release without shutting down your own system.
BPC-157	Soft-tissue healing	Body Protection Compound. Used for tendon, ligament, and gut repair on a doctor's plan.
TB-500	Recovery / mobility	Thymosin Beta-4 fragment. Often paired with BPC-157 for chronic soft-tissue issues.
Tesamorelin	Body composition	GHRH analog. Studied for visceral fat reduction and lean mass support.
MK-677 (oral)	Appetite / sleep / GH	Not a peptide technically (small molecule) but commonly stacked. Raises ghrelin and GH; raises appetite and water weight.

How protocols fit into a real training plan

Peptides do not replace progressive overload, protein, or sleep. They amplify recovery so you can train hard more often and hold lean mass through cuts. Without the base, you're just paying for water weight and better sleep.

Train first. A real weekly plan from the Plan Builder beats any compound.
Protein floor. 0.8-1.0 g per lb of body weight, daily, tracked in the Food Tracker.
Sleep target. 7-9 hours. GH secretagogues amplify what sleep already does; they don't replace it.
Track outcomes. Log doses and cycle dates in the Protocol tracker so your doctor can see what worked.

FAQ

Are peptides legal?

Many are legal with a prescription from a licensed physician in your country. They are banned by WADA for tested athletes. Always check the regulations that apply to you.

Can I buy peptides online?

Research-only websites operate in a gray area and are not held to pharmaceutical purity standards. STAKD strongly recommends sourcing only through a licensed clinic.

How long until I see results?

Soft-tissue compounds (BPC-157, TB-500) often show effects in 2-4 weeks. GH stacks show body-comp changes over 8-12 weeks when training and nutrition are dialed.

Do peptides have side effects?

Yes. Water retention, numbness, elevated blood sugar, and injection-site reactions are all reported. This is why a physician's monitoring matters.
