What Each Compound Does
Dry Lean Muscle
Quality muscle gains without water retention or bloat. Nandrolone conversion keeps tissue lean and hard throughout the cycle.†
Strength Output
Androgen receptor activation drives progressive strength increases week over week without DHT side effects.†
Recomposition
Osta-Plex excels in recomp protocols — building lean tissue while supporting fat reduction simultaneously.†
Enhanced Pumps
Osthole increases nitric-oxide synthase for improved blood flow and muscle pumps during training sessions.†
No Estrogen Side Effects
Zero estrogen conversion means no gyno risk, no water retention, and no need for an on-cycle estrogen blocker.†
Stackability
Osta-Plex's non-overlapping mechanism makes it ideal for stacking with other prohormones for amplified results.†
Dosing & Cycle Parameters
Take 1 tablet in the morning and 1 tablet in the evening. Tablets may be taken with or without food. New users: run a 4-week cycle first to assess tolerance before extending to 6–8 weeks. Do not exceed 4 tablets per day. Each bottle provides a full 30-day supply at the standard 2-tablet daily dose.
PCT Is Required — Don't Skip It
A 4-week PCT is mandatory after every Osta-Plex cycle. PCT restores natural testosterone production, rebalances hormones, and locks in your gains. Arimiplex is the recommended PCT for Osta-Plex. For longer 6–8 week cycles, consider a full PCT stack.

Is Osta-Plex a SARM?
No — Osta-Plex is a legal prohormone, not a SARM. It is classified as a non-steroidal androgen receptor modulator, meaning it targets androgen receptors selectively without the legal or regulatory issues associated with SARMs. It is 100% legal in the USA and sold as a dietary supplement without a prescription.
What makes Osta-Plex different from other prohormones?
Osta-Plex is unique because it does not convert to DHT or estrogen. Most prohormones carry risk of water retention, gyno, or hair loss through one of these pathways. Osta-Plex's 19-Nor-DHEA Enanthate is 5-alpha-reduced, eliminating DHT conversion entirely, while the formula also has no estrogenic metabolites. The result is a dry, clean muscle-building experience more similar to SARM-like compounds than traditional prohormones.
How long should I run Osta-Plex?
4 to 8 weeks, followed by a mandatory 4-week PCT. New users should run a shorter 4-week cycle first to assess how their body responds. After a 4-week cycle, take at least 4–8 weeks off before running again — or extend to a full 8-week cycle on the second run.
Do I need PCT after Osta-Plex?
Yes — a 4-week PCT is required after every cycle. Arimiplex is the recommended PCT for Osta-Plex. For longer cycles, a full PCT stack is advised. PCT restores your natural testosterone production and protects the gains you made on-cycle.
Is Osta-Plex good for cutting or bulking?
Both — but it excels at recomposition and cutting. Osta-Plex produces dry, lean muscle gains without water retention, making it ideal for athletes who want to build muscle while staying lean. For a lean bulk, it pairs well with Andriol or Halodrol. For pure cutting or recomp, stack it with Anavar or Winstrol through the Pre Nutrition Cut & Definition or Recomp stacks.
Can women use Osta-Plex?
No. Osta-Plex is not recommended for women. It increases testosterone levels significantly, which can cause virilization effects in women — including increased facial hair, voice changes, and other androgenic side effects. Consult a physician before any hormonal supplement.
Can I stack Osta-Plex with other prohormones?
Yes — Osta-Plex is an excellent stacking compound because its mechanism of action is distinct from most other prohormones. It does not compete or overlap with 1-Andro, 4-Andro, or 19-Nor-DHEA-based compounds. The Pre Nutrition Recomp Stack pairs it with Dymethazine and Decabolin for maximum effect. It also stacks well with Andriol or Halodrol depending on your goal.
