Mass & Strength
Stack
Hi-Tech Pharmaceuticals · Prohormone Bulking Stack · 3 Tiers · Cyclasome Delivery
The Hi-Tech Pharmaceuticals Mass & Strength Stack is the prohormone bulking stack for lifters who want real size on the bar and in the mirror — not water weight. Each tier pairs a 4-Andro testosterone base with the anabolic compounds that match your experience, so a first-cycle beginner and a fourth-cycle veteran both get a protocol that may support lean muscle gains, strength output and recovery.† Bundled pricing beats buying the bottles one at a time, every tier.
Three protocols, one goal: more muscle and more weight on the bar. Start where your experience puts you — the tier table underneath tells you exactly which one that is.

| Tier | You are… | Built for | Expect† |
|---|---|---|---|
| Beginner — $115 | New to prohormones. 1+ year of consistent lifting and an established diet. | A clean first cycle that teaches you how your body responds to a test base.† | Fuller, harder muscle and steady strength progress over 6–8 weeks.† |
| Intermediate — $160 | Finished at least one cycle and PCT. Ready for a 19-Nor mass compound. | Visible size with lean-gain support from Osta-Plex.† | Noticeable size and strength jumps by week 3–4.† |
| Advanced — $185 | Multiple cycles under your belt. Know your bloodwork and your PCT. | The heaviest anabolic environment in the lineup with liver support built in.† | Rapid fullness, pump and top-end strength.† Not for first-timers. |
A stack is only as good as the support around it. Every Mass & Strength tier requires PCT, and the Beginner and Intermediate tiers do not include Liver-Rx (Advanced does). Grab what your tier needs before checkout.
Liver-Rx 90ct — $14.99
Hi-Tech Liver-Rx supports healthy liver enzyme values and normal liver function during a prohormone cycle.† One 90ct bottle covers a full 8-week run. Already included in the Advanced tier.
Add Liver-Rx →Novedex XT 60ct — $49.99
The right PCT for a two-compound first cycle. Novedex XT supports natural testosterone recovery and healthy estrogen balance after your cycle ends.† Start it the day after your last on-cycle dose.
Add Novedex XT →Arimiplex PCT 60ct — $49.99
Multi-compound cycles call for Hi-Tech's most complete PCT. Arimiplex supports natural testosterone, estrogen control and cortisol balance across the full 4-week recovery window.†
Add Arimiplex →Compound roles — Mass & Strength Stack
Lean Size That Stays†
A 4-Andro base plus 19-Nor and non-steroidal support may promote muscle gains that look and feel like muscle, not water.†
More Weight On The Bar†
Users typically report strength progress inside the first two to three weeks as nitrogen retention and fullness climb.†
Faster Recovery†
Every tier is built to support recovery between heavy sessions so you can train with the frequency a bulk demands.†
Fullness & Pump†
Cyclasome-delivered compounds may support muscle fullness and training pump from the first week of the cycle.†
Joint Comfort Under Load†
Decabolin and Osta-Plex may support joint comfort while you push heavier weights week over week.†
A Clear Progression Path
Beginner, Intermediate, Advanced — each tier is a step up, so your second and third cycles are already mapped out.
Mass & Strength Cycle — 8 Weeks On · 4 Weeks PCT
Take each compound as directed on its label — most Hi-Tech prohormones run 1 tablet 2–4 times daily with meals. Run 6–8 weeks on-cycle, never longer than 8. Begin PCT (Novedex XT or Arimiplex) the day after your last dose and run it a full 4 weeks. Take at least as much time off as you spent on-cycle before your next run. Add Liver-Rx from day one on the Beginner and Intermediate tiers.
Do Not Use If
Under 21, female, pregnant or nursing, or if you have a history of high blood pressure, heart, liver, kidney, prostate or thyroid conditions, or take any prescription medication. For experienced male athletes only. Consult a healthcare professional before starting any prohormone cycle.
Possible Side Effects
Prohormone cycles are associated with temporary changes in blood pressure, cholesterol, mood, libido and liver enzyme values. Stop use and consult a physician if you experience any adverse reaction. Never exceed the labeled dose or cycle length.
Sports Testing Notice
Compounds in this stack (including andro-based prohormones, 19-nor metabolites and PCT aromatase inhibitors) are prohibited by WADA and most sanctioned sports bodies. Do not use if you are subject to drug testing.
The Bulking Stack Richmond Lifts On
Mass & Strength is our best-selling prohormone stack because the Intermediate tier delivers the size people come in asking for — at $160 instead of $189.97 separately.
GMP-Manufactured
Every Hi-Tech Pharmaceuticals compound in this stack is produced in a cGMP-registered facility. Verified sourcing — not a gray-market mystery bottle.
Ships From Richmond, VA
Orders placed by 2PM ET ship same business day from our store at 9915 Hull Street Road. Discreet packaging to all 50 states.
Owner-Operated Guidance
Pre Nutrition is owner-run. Message us before you order or mid-cycle and you get a real answer from someone who knows these compounds.
Are these steroids?
No. Every compound in the Mass & Strength Stack is a legal dietary supplement sold without a prescription. Prohormones like Andriol and Decabolin are naturally occurring hormone precursors — they are different compounds from controlled anabolic steroids and are manufactured by Hi-Tech Pharmaceuticals in a cGMP-registered facility.
Which Mass & Strength tier should I start with?
If this is your first prohormone cycle, start with the Beginner tier — even if you have lifted for years. If you have completed at least one cycle and PCT, the Intermediate tier is the one most customers come back for. Advanced is for lifters with several cycles behind them who know their bloodwork. Unsure? Message us before you order.
Do I need PCT after the Mass & Strength Stack?
Yes — every tier. PCT supports your body's natural testosterone recovery after a cycle.† Beginner pairs with Novedex XT; Intermediate and Advanced pair with Arimiplex PCT. Neither is included in this stack, so add it at checkout.
Is Liver-Rx included?
Only in the Advanced tier. Beginner and Intermediate users should add the $14.99 90ct bottle — it is the cheapest piece of a cycle and the one you least want to skip.†
How much size can I expect?†
Results depend on your training, calories and sleep. Customers running the Intermediate tier with a real surplus most often report noticeable fullness in weeks 2–3 and strength increases through week 8.† Individual results vary with any supplement.
How long is a Mass & Strength cycle?
6–8 weeks on-cycle followed by 4 weeks of PCT. Never run longer than 8 weeks, and take an equal amount of time off before your next cycle.
Can I buy the compounds separately?
Yes — but the stack saves you $14.98 to $29.97 versus the individual bottles, and the Advanced tier includes Liver-Rx. Buying separately only makes sense if you already own one of the compounds.
