Old School Bulk
Test 400 + NPP + Primobolan — a golden-era protocol with modern esters.
Overview
A golden-era inspired build: high-concentration testosterone for the base, fast-acting NPP for nandrolone's fullness and joint relief without deca's months-long tail, and Primobolan for the clean tissue that defined that look. NPP's short ester means the nandrolone is controllable — dial it weekly, clear it in days. Fewer total injections than the classic equivalents thanks to Test 400's concentration.
Who it's for
- 01Advanced researchers who want nandrolone benefits with a fast exit ramp
- 02Fans of the golden-era aesthetic — full but never bloated
- 03Researchers consolidating weekly injection volume (Test 400 = fewer mL)

~350 mg/week. Short ester clears within days of the last pin.
Weekly Protocol
Weeks 1–10: all three compounds. Weeks 11–12: test + primo as NPP exits (it clears fast). Weeks 13–14: clearance. PCT weeks 15–16 (+2): Nolvadex 20 mg + Clomid 25 mg daily × 4 weeks. Bloodwork weeks 4 and 10: E2, prolactin (19-nor on board), CBC, lipids. NPP's EOD schedule is non-negotiable — its short ester needs the frequency for stable levels.
| Compound | Dose | Frequency | Weeks |
|---|---|---|---|
| Test 400 | 400 mg | Weekly | 1-12 |
| NPP | 100 mg | Every other day | 1-10 |
| Primobolan Enanthate | 200 mg | 2× weekly | 1-12 |
Expected Outcomes
- 15–25 lb over 12 weeks — fuller than a lean bulk, drier than an off-season bulk
- Joint comfort under progressive heavy loads (NPP)
- Quality tissue retention post-cycle from the primo component
- Strong suppression — full PCT mandatory
Support Requirements
Items referenced in the protocol. Some are included in the stack; support-only items may need to be ordered separately.
Estradiol control — Test 400 aromatizes substantially
PCT — primary SERM
PCT — stacked SERM
Advised — nandrolone suppression runs deep
Safety & Warnings
- Test 400 is high-concentration — post-injection soreness is common; rotate sites strictly.
- Nandrolone prolactin warnings apply — monitor, have Cabergoline access.
- EOD pinning for 10 weeks demands site discipline: quads, glutes, delts, ventroglutes in rotation.
- Not a first or second cycle.
Frequently Asked
NPP vs Deca — why the short ester here?
Control. NPP gives you everything nandrolone offers — fullness, joint relief, mass — but exits the body in days instead of months. If prolactin or mood sides appear, you're clean within a week. Deca commits you for the duration.
Why only one Test 400 injection per week?
Test 400 blends long esters at 400 mg/ml, so weekly pinning keeps levels acceptably stable while halving injection volume. If you prefer flatter curves, split it into two 0.5 ml injections — same weekly total.
