The Winter Prohormone Cycle

Halodrol And Bold Cycle

Winter continues to be the most popular periods of time to bulk up and with winter starting to kick into full gear we want to really take advantage of this time to pack on as much mass as possible before we have to switch gears for the warmer weather. We wanted to put together a good stack how-to based on two of the more popular designer steroids/prohormones available BOLD (1,4AD) and H-DROL (Halodrol) for even better bulking results users can replace h-drol with p-mag (promagon) as they’re entirely interchangeable.

This stack is not for novices, ideally this stack would be for someone who has completed 2-3 successful cycles previously, when you’re just getting started out there’s no need to stack compounds. We are running both of these compounds at their ‘sweet spots’ therefore this will be quite a potent stack for someone without proper cycle and lifting experience.

Halodrol (H-Drol)

Halodrol (now referred to as H-Drol) is a methylated prohormone created by Gaspari Nutrition, the chemical makeup is (4-Chloro-17a-Methyl-Androst-1,4-Diene-3-17b-Diol), h-drol is methylated therefore it puts stress on our livers, h-drol shouldn’t be stacked with another methylated compound and should be ran with appropriate liver support. H-drol is quite potent and works well while cutting, recomping or bulking and is mild enough to be stacked with other non-methylated compounds (such as BOLD).

BOLD (1,4AD)

BOLD (1,4AD) is a legal anabolic steroid/prohormone made popular by iForce Nutrition, the chemical makeup of BOLD is (1,4-androstadiene-3b,17b-dione or androst-1,4-diene-3b,17b-dione), BOLD is non-methylated compound therefore it’s easy on the liver which makes it great for stacking with methylated steroids and has a very low occurrence of side effects. BOLD happens to also be a great bulking supplement, while also increasing appetite, but it can be a bit on the expensive side to run.

Bodily Protection

Like many prohormone on the market bold and h-drol can have a negative impact on blood pressure, lipid values, cholesterol levels and will stress our bodies endocrine system, in the case of h-drol as noted it will also put additional strain on our livers. Anytime you’re stacking two designer anabolic steroids or prohormones the potential for side effects is elevated, however with proper supplementation and planning we can help our bodies mitigate most of the risk and or reduce the severity of side effects. Luckily for the past couple of years companies have been offering all-in-one cycle protection that are designed specifically to help prevent side effects and or in the event of side effects (such as elevated blood pressure) reduce their impact. For this stacked cycle begin pre-loading either life support or cycle support one week before starting the cycle, make sure you run one of these products through the entire duration of your cycle including PCT so make sure you buy enough. These products will assist your body with maintaining healthy blood pressure, prostate health, liver function and lipid profile by utilizing popular herbs such as Hawthorn Berry (BP), NAC (liver), Milk Thistle (liver), Saw Palmetto (prostate) among others. Please follow the manufactures recommended dosage (as per bottle) as it’s the dosage known to work best.

Dosing & Length

We won’t get into all the dosing possibilities, because they’re so many options, but for this theoretical stack below is the dosing and length we will be using.

Compound Week 1 Week 2 Week 3 Week 4 Week 5 Week 6 Week 7 Week 8
BOLD 600MG 800MG 800MG 800MG 800MG 800MG 800MG 800MG
H-Drol none none none 50mg 75mg 75mg 75mg 75mg


Post Cycle Therapy (PCT)

As noted this article assumes you have past anabolic steroid or prohormone experience therefore we won’t get into WHY you need to PCT, please read our informative bibles on h-drol and bold for that information. For this stack you will most definitely need a prescription grade PCT utilizing a SERM and Nolvadex (Tamoxifen Citrate) fits that bill and is also the most popular SERM among steroid and prohormone users below is how this stacks PCT is being laid out.

  1. Nolvadex (Tamoxifen Citrate). Comes in Liquid or Pill form.
  2. Optional (But highly-recommended): Competitive Edge Labs – P.C.T Assist

Below is the example PCT when using a research drug (such as Nolvadex aka Tamoxifen Citrate, as we are in this case).

Week1-2 Nolvadex 20mg & P.C.T Assist (5 caps) | Week 3-4 Nolvadex 10mg & P.C.T Assist (5 caps) | Week 5 P.C.T Assist (4 caps)

Putting it together

Here is how the cycle would look on paper from start to finish, including everything.

Life/Cycle Support Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes

H-Drol no no no no 50mg 75mg 75mg 75mg 75mg no no no no
Grape Antioxidant no Yes Yes Yes Yes Yes Yes Yes Yes no no no no
Nolvadex no no no no no no no no no 20mg 20mg 10mg 10mg



It’s recommended that users supplement with a quality Multi-Vitamin and Fish Oil throughout the ENTIRE cycle, keep something on hand for your joints in the event you experience some discomfort Universal Animal Flex works wonders. You should stop taking any other supplements on Cycle as well such as Creatine, NO, Test Boosters and so on, these should be saved for PCT in order to preserve strength. It’s heavily recommended that during PCT, you add Creatine and a Cell Volumizer type of product. Supplementing with Protein is highly recommended on cycle


Users who are on anti-depressant or anti-anxiety medication may experienced increased anxiety/depression while on cycle and during PCT. It is HEAVILY advised not to drink alcoholic drinks while on Cycle & PCT, doing so will put significant strain on the liver and can result in a major health hazard. Users should avoid using stimulants on cycle as blood pressure may elevate too high and possibly cause fainting. In general, avoid starting any new medications while on cycle or just before, if you’re concerned about a possible interaction consult your doctor. Users should also eat a clean diet on cycle.
